Home » Industrial Belt » Top 10 China Power Transmission Belt Manufacturers in 2026

Quick Link

China has a broad power transmission belt industry serving industrial machinery, agriculture, automotive systems, packaging equipment, robotics, household appliances, and replacement distribution. Manufacturers range from listed V-belt groups to specialists producing polyurethane timing belts in small custom batches. Their product ranges and engineering strengths are not interchangeable.

This guide compares ten identifiable Chinese manufacturers with public evidence of belt production. It is a curated procurement shortlist, not a laboratory-tested ranking. TranBelt publishes the article and appears in the list as a manufacturer, OEM service provider, and international-brand distributor. That relationship is disclosed so buyers can evaluate every company using the same technical and commercial checks.

Key Takeaways

Chinese manufacturers produce rubber and polyurethane timing belts, wrapped and cogged V-belts, Poly-V belts, flat belts, agricultural belts, and custom profiles.
The right manufacturer depends on drive geometry, transmitted power, speed, duty cycle, pulley size, environment, required life, and order volume.
A matching printed code does not prove interchangeability; tooth geometry, datum width, cord, compound, tolerances, and testing must also match.
Buyers should approve technical drawings, samples, batch tests, packaging, traceability, and warranty terms before placing a production order.

TranBelt combines manufacturing and OEM work with access to imported brands, making it useful when a buyer needs custom and branded options in one inquiry.

Top 10 Power Transmission Belt Manufacturers in China

1. TranBelt Transmission Solutions

Company Background

TranBelt Transmission Solutions is a Shenzhen-based industrial belt manufacturer and distributor serving global distributors, equipment builders, system integrators, and end users. Its business model combines in-house production, OEM and ODM projects, partner manufacturing, stock supply, and distribution of established international belt brands.

TranBelt’s main advantage is its ability to combine in-house manufacturing with OEM customization and international-brand distribution. Buyers can source high-quality TranBelt products, develop non-standard belts to match specific machinery, or purchase brands such as Gates, Continental, Bando, Mitsuboshi, Megadyne, and Optibelt at competitive distributor pricing through one supplier.

Product Line

TranBelt supplies rubber and polyurethane timing belts, open-ended timing belts, V-belts, Poly-V belts, round belts, specialty profiles, pulleys, tensioners, and related drive components. It can also provide products from Gates, Continental, Bando, Mitsuboshi, Megadyne, and Optibelt at distributor pricing.

Its OEM capability covers non-standard lengths, widths, compounds, cords, coatings, profiles, perforations, backing materials, and molded parts. This range allows a buyer to compare a custom TranBelt product with an imported branded belt instead of treating them as unrelated purchasing channels.

Why We Recommend It

TranBelt is particularly useful for international buyers who need flexible order quantities, engineering communication, brand alternatives, and consolidated procurement. A machine builder may source customized PU belts for a new design while purchasing branded maintenance belts for installed equipment through the same commercial partner.

The broad supply model requires clear traceability. Each quotation should identify whether the item is TranBelt-manufactured, OEM-produced by a partner factory, or an original imported brand. That distinction should also appear on packaging, certificates, inspection records, and warranty terms.

2. Sanlux Co., Ltd.

Company Background

Sanlux Co., Ltd. is a Shenzhen-listed Chinese manufacturer with a long-established position in the rubber V-belt industry. Company disclosures describe a nationwide sales network, product development capabilities, manufacturing scale, and repeated recognition by the China Rubber Industry Association.

Sanlux is a relevant benchmark for Chinese V-belt production because its manufacturing activity is supported by both an operating website and public-company reports. Buyers should still distinguish group-level information from the exact factory and product series quoted for an order.

Product Line

Sanlux manufactures wrapped V-belts, raw-edge cogged belts, narrow wedge belts, banded belts, agricultural belts, variable-speed belts, automotive belts, and selected synchronous products. Its catalog serves industrial machinery, agricultural equipment, ventilation, compressors, pumps, and replacement distribution.

Different series use different rubber compounds, cover fabrics, cord materials, and manufacturing tolerances. Buyers replacing an existing belt should specify the profile, effective or datum length, matching requirements, pulley dimensions, duty, and environmental conditions.

Why We Recommend It

Sanlux is a strong candidate for high-volume industrial V-belt programs and distributors that need a broad range of conventional profiles. Its established market presence and public reporting make initial company verification easier than with many small private factories.

For precision synchronous or highly customized polyurethane applications, a specialist may offer a better fit. Sanlux is most compelling when V-belt depth, manufacturing volume, availability, and channel support are the primary purchasing factors.

3. Sanwei Holding Group Co., Ltd.

Company Background

Sanwei Holding Group Co., Ltd. is a listed manufacturing business headquartered in Zhejiang. Its annual reports identify rubber transmission belts as an established product category and discuss manufacturing processes, raw materials, sales channels, technology development, and industrial standards.

Sanwei also operates in other business areas, so the buyer should confirm the legal subsidiary and production plant named in the quotation. Group scale does not automatically prove that every site produces every belt construction.

Product Line

Sanwei’s transmission products include wrapped V-belts, raw-edge belts, banded belts, agricultural belts, variable-speed products, and timing belts. These serve general industry, agricultural machinery, power equipment, and replacement markets.

Its older technical catalogs show several classical and specialty transmission belt constructions. Current availability, compound formulations, cord systems, dimensions, and certifications should be confirmed directly because group portfolios and production programs change over time.

Why We Recommend It

Sanwei is a credible candidate for buyers seeking an established Chinese industrial rubber group with documented belt manufacturing. Its range can support distributors and OEMs purchasing both standard V-belts and application-specific agricultural or synchronous products.

Ask for current factory-specific technical sheets and test methods. This ensures that published corporate capabilities translate into measurable properties for the exact belt series being evaluated.

4. Ningbo Yujiang Special Rubber Belts Co., Ltd.

Company Background

Ningbo Yujiang Special Rubber Belts Co., Ltd. was established in 1993 and is associated with Ningbo Fubang Holding Group. It focuses on automotive and industrial transmission system products and has public evidence of long-running belt manufacturing activity.

Yujiang’s product positioning spans original-equipment and replacement applications. Automotive references require careful interpretation because historical customer relationships do not automatically confirm a current supply contract or approval for every model.

Product Line

The company manufactures rubber timing belts, ribbed V-belts, conventional V-belts, tensioners, and related transmission components. Its products serve engines, industrial machinery, appliances, and other synchronized or friction-drive systems.

Automotive and industrial timing belts can share profile names while using different compounds, cords, tooth fabrics, and life requirements. Buyers should identify whether a quoted belt is designed for engine timing, auxiliary drives, or general industrial machinery.

Why We Recommend It

Yujiang is worth considering when a project needs rubber timing belts, multi-rib belts, and related tensioning components from one source. Its experience in automotive and industrial products suggests a stronger understanding of fatigue, heat, tooth wear, and dimensional control than a general rubber trader.

For safety-critical engine applications, require model validation, current quality-system documents, lot traceability, fatigue data, and a clear warranty. A visually similar timing belt is not an acceptable substitute without technical confirmation.

5. Ningbo GUL-TZ Rubber Belt Co., Ltd.

Company Background

Ningbo GUL-TZ Rubber Belt Co., Ltd. was established in 1992 in Yuyao, Zhejiang. The company describes a dedicated rubber transmission belt factory, participation in national and industry standards, an engineering technology center, and ISO management-system certifications.

Its public history includes equipment expansion and development work for synchronous and multi-ribbed belts. Those details provide a useful starting point for supplier qualification, although published capacity numbers remain company claims until audited.

Product Line

GUL-TZ specializes in rubber timing belts, V-ribbed belts, open-ended belts, double-sided timing belts, coated belts, and timing pulleys. The range targets machinery, household appliances, office equipment, automation, and other compact power transmission systems.

The inclusion of pulleys can help designers verify the belt-and-pulley interface. Even so, the buyer must confirm profile standard, pitch, tooth form, pulley groove geometry, minimum tooth engagement, installation tension, and alignment.

Why We Recommend It

GUL-TZ is a strong specialist for rubber synchronous and ribbed-belt applications. Its participation in standards work and long manufacturing history make it relevant to OEMs that need more technical support than a catalog reseller can provide.

Request samples from the intended production process, not only demonstration pieces. Evaluate dimensional consistency, tooth fabric, cord position, adhesion, running noise, heat buildup, and fatigue under representative load.

6. Zhejiang Sanmen Kaitai Belt Co., Ltd.

Company Background

Zhejiang Sanmen Kaitai Belt Co., Ltd. traces its operations to 1987 and focuses on synchronous belt development and manufacturing. The company is based in Sanmen County, a major Chinese belt-production cluster, and reports a dedicated production facility for polyurethane transmission products.

Kaitai’s specialization separates it from companies centered on wrapped rubber V-belts. It is more relevant to automation, positioning, linear motion, packaging, and precision machinery.

Product Line

The company produces cast polyurethane timing belts, thermoplastic polyurethane open-ended belts, joined belts, truly endless belts, multi-ribbed belts, flat belts, micro-belts, timing pulleys, and specially fabricated products. Available customization can include backing, profiles, machining, perforations, and special widths.

PU belt selection requires more than pitch and length. Buyers should define tensile cord, polyurethane hardness, operating temperature, chemical exposure, pulley diameter, speed, load direction, joint type, and positioning accuracy.

Why We Recommend It

Kaitai is a strong candidate for custom polyurethane timing belt projects and automation equipment. Its CPU and TPU product range gives designers options between molded endless, extruded open-ended, joined, and specially fabricated constructions.

The manufacturer should review the complete drive, especially where small pulleys, high acceleration, vacuum holes, welded profiles, thick backing, or reverse bending could reduce belt life.

7. Ningbo Fulong Synchronous Belt Co., Ltd.

Company Background

Ningbo Fulong Synchronous Belt Co., Ltd. is an established Chinese transmission belt producer associated with a broad timing belt catalog. Industry directories and product documentation identify the company as a manufacturer serving domestic and export markets.

Because some public materials are catalogs rather than detailed corporate disclosures, buyers should confirm the current legal entity, factory location, management certifications, and production scope during qualification.

Product Line

Fulong offers industrial rubber timing belts, automotive timing belts, double-sided belts, open-ended belts, V-belts, ribbed belts, and related synchronous transmission products. Common profiles include trapezoidal and curvilinear tooth systems for industrial machinery.

Exact profile compatibility matters. HTD, STD, RPP, T, AT, and imperial tooth forms are not automatically interchangeable even when nominal pitch appears similar. Pulley geometry and belt tooth design must be verified together.

Why We Recommend It

Fulong is useful for buyers seeking a broad timing belt selection from a dedicated Chinese producer. Its catalog coverage can support replacement distribution and machinery applications with several metric or imperial profiles.

Qualification should focus on current technical data and lot consistency. Ask for dimensional tolerances, cord material, compound, tooth fabric, minimum pulley recommendations, tensile data, fatigue methods, and matching procedures.

8. Ningbo Frank Power Transmission Co., Ltd.

Company Background

Ningbo Frank Power Transmission Co., Ltd. was founded in 2008 and focuses on synchronous drive products for industrial machinery. The company exports under the FRK POWER name and presents a product range covering both polyurethane and rubber constructions.

Frank Power is smaller and younger than listed manufacturers such as Sanlux. Its value lies in product breadth and customization rather than public-company scale.

Product Line

The company offers rubber timing belts, PU open-ended belts, cast endless PU belts, joined belts, coated timing belts, Poly-V belts, Polyflex-style belts, classical and wedge V-belts, flat belts, and pulleys. Applications include textiles, packaging, printing, food machinery, appliances, machine tools, and sports equipment.

Custom coating and fabrication can change flexibility, heat, tracking, and minimum pulley requirements. Drawings should identify every added layer, profile, hole, joint, and tolerance.

Why We Recommend It

Frank Power is a practical candidate for machinery OEMs that want several synchronous belt constructions and pulleys from one supplier. Its range supports prototyping, replacement, and special fabrication across PU and rubber belt families.

Buyers should audit testing capacity and approve production samples. A broad online catalog is useful, but it does not prove equal production maturity across every listed series.

9. Zhejiang Huanling Rubber Belt Co., Ltd.

Company Background

Zhejiang Huanling Rubber Belt Co., Ltd. operates from Deqing, Zhejiang, and focuses on industrial power transmission belts. Its public catalog presents both V-belt and synchronous belt families for machinery and replacement markets.

Huanling’s clear product specialization makes it more appropriate for this list than a general rubber-products supplier. Buyers should still verify company registration, factory conditions, current certifications, and export references before a large order.

Product Line

The range includes classical wrapped V-belts, wedge belts, cogged V-belts, ribbed belts, banded belts, HTD timing belts, STD timing belts, and specialty industrial products. This coverage suits pumps, compressors, fans, agricultural machinery, and general plant equipment.

For sets of V-belts, matching tolerances matter as much as the printed size. Request matched-set controls where several belts share a drive, and specify whether length is inside, outside, datum, or effective.

Why We Recommend It

Huanling is worth considering for standard and specialty industrial V-belt sourcing. The combination of wrapped, cogged, wedge, ribbed, and synchronous belts can reduce the number of suppliers needed by a maintenance distributor.

Its suitability should be confirmed through samples and application testing, especially for high shock, high temperature, small pulley, clutching, backside-idler, or agricultural duties.

10. TRANSCO Belt

Company Background

TRANSCO Belt presents itself as a Ningbo-based rubber power transmission belt manufacturer serving automotive, industrial, material-handling, OEM, and aftermarket customers. Its product pages show a focused range rather than a generic trading catalog.

The TRANSCO trade name should be matched to the exact legal manufacturing and contracting entity on quotations, certificates, invoices, and export documents. This avoids ambiguity where a brand and factory company use different names.

Product Line

TRANSCO produces automotive and industrial timing belts, wrapped V-belts, raw-edge cogged belts, Poly-V belts, and related rubber drive products. The range covers common replacement profiles and customized OEM requirements.

For branded replacement programs, buyers should approve labeling, packaging, traceability, shelf-life marking, and anti-counterfeit controls in addition to belt performance. Aftermarket presentation cannot compensate for weak manufacturing data.

Why We Recommend It

TRANSCO is a suitable candidate for distributors and OEM buyers seeking several rubber belt categories from one export-oriented supplier. Its combined automotive and industrial focus can support mixed product programs.

Before approval, compare fatigue life, dimensional stability, adhesion, heat aging, oil exposure, noise, and pulley compatibility against the target application or reference belt.

How Were These Power Transmission Belt Manufacturers Evaluated?

The shortlist applies five practical filters. Each company must have an identifiable Chinese operation and public evidence of manufacturing power transmission belts. Its catalog must include products that transfer mechanical power, such as timing belts, V-belts, Poly-V belts, flat belts, or polyurethane synchronous belts. Conveyor-only manufacturers were excluded.

The evaluation also considers product specialization, technical information, customization, and buyer access. Public-company reports, official corporate websites, product catalogs, standards participation, quality-system statements, and identifiable factory information provide stronger evidence than marketplace listings alone.

This method does not prove that all ten manufacturers deliver equal quality. No common independent fatigue test was conducted, and company-published capacity or award claims remain self-reported unless supported by a separate source. Quality also varies by product family, compound, cord, mold, production line, and batch.

The list should therefore help buyers build a request-for-quotation group. Final approval requires technical review, samples, factory qualification, batch controls, and application testing.

Which Types of Power Transmission Belts Do Chinese Manufacturers Produce?

Chinese manufacturers produce nearly every common flexible drive belt family. The correct category depends on whether the drive requires friction, positive engagement, variable speed, precise positioning, compact routing, quiet operation, or easy customization.

V-belts transmit power through wedging action in pulley grooves. Classical Z, A, B, C, and D profiles remain common, while narrow wedge SPZ, SPA, SPB, and SPC profiles carry more power in compact drives. Wrapped belts resist external wear, while raw-edge cogged belts flex more easily and often run efficiently on smaller pulleys.

Timing belts engage toothed pulleys without intentional slip. Rubber belts commonly use fiberglass or aramid cords with protective tooth fabric. Polyurethane belts often use steel or aramid cords and support open-ended linear drives, joined belts, molded endless belts, coatings, and welded profiles. Tooth systems include trapezoidal, HTD, STD, RPP, T, AT, and imperial forms.

Poly-V belts, also called ribbed belts, combine multiple longitudinal ribs with a thin flexible body. They suit compact, high-speed drives and backside idlers. Industrial PH, PJ, PK, PL, and PM sections must match the corresponding pulley geometry.

Flat belts can operate at high speed with low vibration and are used in textile machinery, paper processing, spindles, rollers, and tangential drives. Belt construction, friction layer, tracking, joint, and pulley crown require careful engineering.

Agricultural and variable-speed belts handle shock, dust, clutching, reverse bending, and changing pulley diameters. These duties often require special cords, sidewall compounds, fabric covers, and matching controls rather than a general industrial belt of the same nominal size.

How Do You Choose a Power Transmission Belt Manufacturer in China?

Define the drive duty. Provide transmitted power, driver and driven speed, duty cycle, starts per hour, shock loading, service factor, and required operating life.
Document the pulley system. State pulley diameters, groove or tooth profile, number of grooves or teeth, center distance, wrap angle, alignment, flanges, idlers, and available installation movement.
Identify the belt standard. Give the exact section, pitch, tooth form, width, length convention, and applicable ISO, DIN, RMA, ARPM, GB, or manufacturer standard.
Describe the environment. Include minimum and maximum temperature, oil, ozone, dust, water, chemicals, UV, static requirements, food contact, cleanroom conditions, and outdoor exposure.
Choose construction deliberately. Compare rubber with polyurethane, wrapped with raw edge, fiberglass with steel or aramid cord, and molded endless with joined or open-ended construction.
Confirm manufacturing responsibility. Identify whether the product is made in-house, outsourced to a partner factory, or supplied as an original international brand. Require matching documentation.
Request technical evidence. Ask for dimensional tolerances, tensile properties, adhesion, hardness, heat aging, fatigue method, electrical properties, and minimum pulley recommendations.
Approve representative samples. Test samples on the actual machine or a representative endurance rig. Include startup, peak load, temperature, noise, tracking, wear, and shutdown conditions.
Control production batches. Define raw-material traceability, inspection frequency, matched sets, lot coding, packaging, shelf life, retained samples, and acceptance criteria.
Compare total value. Consider tooling, minimum order, lead time, rejected-parts policy, freight, inventory, technical support, expected life, machine downtime, and warranty.

Are Chinese Power Transmission Belts Reliable?

Chinese power transmission belts can be reliable when the manufacturer and belt construction are matched to the drive. China has listed V-belt companies, long-established rubber timing belt producers, specialized polyurethane manufacturers, and export-focused OEM factories. It also has traders selling visually similar belts without sufficient engineering control.

Reliability depends on measurable factors. The tensile cord must remain accurately positioned and consistently tensioned. Rubber or polyurethane must be compounded and cured correctly. Timing-belt teeth must match the pulley profile, while V-belt sidewalls must maintain the intended angle and datum dimensions. Adhesion, fatigue resistance, heat aging, oil resistance, and dimensional consistency affect actual service life.

A low price does not automatically indicate poor quality, and a polished brand does not guarantee the right application. Buyers should compare samples under representative loads, audit the production source, and make test requirements part of the purchase order. For critical drives, retain batch samples and monitor early installations before approving wider use.

Frequently Asked Questions

Who Is the Largest V-Belt Manufacturer in China?

Sanlux reports that it has ranked first in China’s rubber V-belt industry for many consecutive years. That statement is supported by its corporate materials and public-company reporting, but “largest” can mean revenue, output, installed capacity, domestic share, or product volume. Buyers should use the specific metric rather than treating the word as universal.

Which Chinese Manufacturers Produce Timing Belts?

TranBelt, Sanlux, Sanwei, Yujiang, GUL-TZ, Kaitai, Fulong, Frank Power, Huanling, and TRANSCO all offer timing or synchronous belt products. Their strengths differ. Some concentrate on rubber automotive or industrial belts, while Kaitai and Frank Power provide broader polyurethane open-ended, joined, coated, or molded-endless options.

What Is the Difference Between Rubber and PU Timing Belts?

Rubber timing belts typically provide good noise control, flexibility, and fatigue behavior for industrial and automotive drives. Polyurethane belts offer abrasion resistance, dimensional stability, clean operation, and extensive fabrication options. The correct choice depends on pulley size, speed, load, temperature, chemicals, joint type, positioning accuracy, and required backing or profiles.

Can Chinese Manufacturers Replace Gates or Continental Belt Models?

They can often produce dimensionally compatible alternatives, but replacement must be verified. Matching a catalog number is not enough. Confirm profile geometry, length convention, width, cord, compound, tooth fabric, static conductivity, temperature range, minimum pulley, tension method, power rating, and expected life. Critical drives require application testing before conversion.

What Information Should Be Included in a Belt RFQ?

Include the machine, application, belt code, drawings, profile, length, width, pulleys, center distance, speed, power, torque, duty cycle, environment, quantity, annual demand, standard, required life, testing, branding, packaging, destination, and delivery date. Also describe current failure symptoms so the supplier does not duplicate an unsuitable construction.

Conclusion

China’s power transmission belt industry includes large V-belt groups, rubber timing belt specialists, polyurethane synchronous belt manufacturers, and flexible OEM suppliers. Sanlux and Sanwei offer established industrial scale, while GUL-TZ, Yujiang, Kaitai, Fulong, Frank Power, Huanling, and TRANSCO serve distinct rubber or PU drive requirements.

TranBelt combines manufacturing and OEM capability with distribution of international brands. Because TranBelt publishes this guide, its inclusion is disclosed rather than presented as an independent award. Whichever company enters your shortlist, approve the exact construction, manufacturing source, technical data, samples, batch controls, and warranty before relying on price comparisons.
