Home » Timing Belt » Top 10 China Rubber Timing Belt Manufacturers (2026 Reviews)

Quick Link

Rubber timing belts remain a practical choice for industrial power transmission because they combine synchronous tooth engagement with flexibility, damping and quiet operation. However, belts with the same printed dimensions can differ in compound, tensile cord, tooth fabric and molding accuracy. These differences affect load capacity, tracking, noise and service life.

This 2026 review compares ten Chinese companies with identifiable rubber synchronous belt products and manufacturing evidence. It focuses on industrial capability rather than treating every automotive belt supplier as an industrial specialist. TranBelt publishes this article and appears in the ranking, so its position is a disclosed commercial assessment rather than an independent laboratory award.

Key Takeaways

Match the complete tooth profile to the pulley instead of relying only on nominal pitch.
Compare rubber compound, tensile cord, tooth fabric and dimensional tolerance before comparing price.
Custom coatings, holes and machined surfaces require approval of the finished belt, not only the base belt.
Verify the production entity and approve representative samples before placing a volume order.

Top 10 China Rubber Timing Belt Manufacturers

Every listed company publishes rubber timing belt products or identifiable synchronous-belt manufacturing information. Ranking position reflects industrial relevance, product breadth, custom capability, technical transparency and accessibility to international buyers. Final belt performance still depends on the approved specification, production batch, pulley condition, alignment, tension and operating environment.

1. TranBelt Transmission Solutions – Best Overall for International Industrial Buyers

Company Background

TranBelt Transmission Solutions is a Shenzhen manufacturer of standard and customized industrial rubber timing belts. It serves distributors, machine builders, repair companies and OEM customers that require catalog replacements or drawing-based production. Its rubber timing belt range covers widely used metric and imperial synchronous-drive systems.

Product Line

Available profiles include HTD, STD, RPP, MXL, XL, L, H and XH families. TranBelt produces single-sided and double-sided belts for power transmission and synchronized multi-shaft arrangements. Rubber compounds, tensile cords and tooth-facing materials are selected according to the profile, load, speed, pulley size and operating environment rather than offered as one universal construction.

TranBelt also manufactures coated and specially processed timing belts. Rubber, sponge, fabric and other backing materials can provide grip, cushioning or product protection. Processing options include grinding, holes, grooves, tooth removal and other drawing-defined features. These capabilities are relevant to packaging, wire and cable, printing, woodworking and product-handling machinery.

Customization should begin with the base belt and pulley geometry. A thick backing or machined surface can change flexibility, heat generation and minimum pulley diameter. TranBelt therefore asks buyers to provide the complete designation, pulley information, operating conditions and processed-belt drawing. Physical samples can be used when an old belt has incomplete or unreadable markings.

In addition to its own OEM rubber timing belts, TranBelt distributes recognized imported brands, including Gates, Continental, Bando, Megadyne, Mitsuboshi and Optibelt. Buyers can compare a branded replacement with a TranBelt-manufactured OEM alternative through one inquiry. Imported belts are offered through distributor-oriented pricing rather than presented as TranBelt production.

Why We Recommend It

TranBelt’s first position reflects its combination of manufacturing, customization, brand supply and international support. Because the company publishes this comparison, buyers should apply the same controls used for every manufacturer: approve the drawing, identify the construction, test a representative sample and define inspection and warranty terms before volume production.

2. Ningbo Fulong Synchronous Belt Co., Ltd. – Best for Established Manufacturing Systems

Company Background

Ningbo Fulong Synchronous Belt Co., Ltd. operates in Cixi, Ningbo and sells products under the CNFULO name. Founded in 1984, the company specializes in industrial and automotive rubber synchronous belts, poly-V belts, variable-speed belts, cut V-belts, polyurethane belts and matching timing pulleys.

Fulong’s long history and focus on synchronous products make it one of the more established factories in this comparison. The company publishes information about product development, testing resources, patents and participation in belt standards. These institutional signals can be useful to OEMs that require a formal supplier-approval process and repeatable long-term production.

Product Line

Its product breadth supports both standard replacement work and integrated belt-and-pulley programs. Sourcing the pulley and belt from one company can simplify responsibility when engagement, runout or flange geometry causes premature wear. Buyers should still request separate drawings and inspection criteria for each component rather than accept a general drive-system description.

Why We Recommend It

Fulong is particularly suitable for distributors and OEMs that value documented systems and production continuity. Confirm whether the quoted item is an industrial or automotive construction, because belts with similar dimensions may use different compounds, cords and tooth fabrics. The order should state the profile standard, width, pitch length, tolerance, compound and required inspection records.

3. Jiangxi Kangqi Industrial Co., Ltd. – Best for Industrial Profile Coverage

Company Background

Jiangxi Kangqi Industrial Co., Ltd. operates from Guixi Industrial Park and markets transmission products under the SABLES and KML brands. The company focuses on rubber timing belts and industrial transmission products, including double-sided belts, coated belts, flat belts, ribbed belts, conveyor belts and timing pulleys.

Product Line

Kangqi serves packaging, printing, textile, paper, food, cable, home-appliance and logistics machinery. This industrial orientation makes it relevant to buyers looking beyond automotive timing belts. Its broad range also allows distributors to combine several rubber power-transmission categories in one supplier program.

The company presents manufacturing and product-development capabilities for rubber synchronous belts, including a large range of molds and special processed products. Buyers should verify the tooling for the exact profile and length rather than assuming that every listed family is produced continuously. Mold availability, minimum quantity and lead time can vary substantially for uncommon dimensions.

Why We Recommend It

Kangqi is a strong candidate for standard industrial profiles and processed belt requirements. An RFQ should specify the rubber compound, tensile member, tooth fabric and dimensional tolerance. For double-sided or coated products, the sample must reproduce the complete production route because secondary processing can affect tracking, flexibility and bond strength.

4. Guangzhou Yonghang Transmission Belt Co., Ltd. – Best for Coatings and Custom Processing

Company Background

Guangzhou Yonghang Transmission Belt Co., Ltd. is a rubber belt manufacturer with a strong emphasis on coated and machined timing belts. Its Guangzhou operation supplies standard timing belts, pull-down belts, haul-off belts, flat belts and application-specific products for packaging, pipe, cable, printing and product-handling equipment.

Product Line

Yonghang’s processing range includes one-piece molded backings, coating, grinding, drilling, milling, water-jet cutting and perforation. It can add rubber, sponge and high-friction surfaces or create slots, holes, grooves, cleats and tooth modifications. This makes the company particularly relevant when the belt contacts the product rather than only transmitting torque.

A processed belt should be treated as a finished engineered part. Backing hardness and thickness influence bending stress and grip, while holes or grooves can approach the tensile cords. Buyers should define datums, tolerances and no-cut zones on the drawing. The approved sample should include the real backing and all machining operations.

Why We Recommend It

Yonghang is a suitable choice for custom surface and handling requirements, but buyers should separate promotional production figures from order-specific evidence. Confirm the base-belt manufacturer, molding method, processing equipment and inspection plan for the quoted item. This is especially important when a custom belt will run at high speed or over small pulleys.

5. Ningbo FRK Power Transmission Co., Ltd. – Best for Broad Tooth-Profile Coverage

Company Background

Ningbo FRK Power Transmission Co., Ltd. operates in Yuyao, Ningbo under the FRK POWER brand. Its catalog covers industrial and automotive timing belts, V-belts, poly-V belts, polyurethane timing belts, coated belts and pulleys. The company presents itself as a producer of synchronous-drive products rather than a single-category reseller.

Product Line

FRK publishes a wide tooth-profile range that includes MXL, XL, L, H, XH, T, AT, HTD, STD and RPP families. This coverage is useful for distributors supporting machinery imported from different regions. It can also reduce the number of vendors needed for metric and imperial replacement inventories.

A broad catalog does not guarantee identical availability or manufacturing routes across every size. Buyers should confirm the mold, compound, cord, tooth fabric and production location for the requested belt. Uncommon lengths may require tooling or minimum quantities, while frequently used profiles may be stocked or produced on regular schedules.

Why We Recommend It

FRK is best evaluated as a multi-profile supply candidate. Provide the complete profile standard rather than a short designation such as “8M,” since several 8 mm tooth families use different geometry. Where the pulley cannot be identified, send a drawing or accurate tooth measurements before approving a replacement.

6. Ningbo Slongwang Synchronous Belt Co., Ltd. – Best for Complete Synchronous Drives

Company Background

Ningbo Slongwang Synchronous Belt Co., Ltd. is based in Cixi, Ningbo and produces synchronous transmission products under the Slongwang name. Its range includes rubber endless belts, rubber open belts, double-sided belts, arc-tooth and trapezoidal profiles, polyurethane belts and matching timing pulleys.

Product Line

The ability to discuss belts, pulleys, clamping components and related hardware with one supplier can help when a machine uses a custom synchronous arrangement. Premature belt wear may originate from pulley runout, tooth mismatch or alignment, so evaluating the complete drive can be more effective than repeatedly replacing the belt.

Slongwang’s public product information confirms broad categories but provides limited English detail for some technical parameters. Buyers should request tooth drawings, pitch-length definitions, width tolerances, cord construction and pulley specifications. For open rubber belts, also confirm the reinforcement arrangement and intended clamping method.

Why We Recommend It

The company is suitable for buyers that want a complete belt-and-pulley package and can manage a drawing-based approval. Confirm which operations are completed internally, especially for pulleys and custom belts. A matched supply package should still include individual inspection requirements for the belt bore, pulley teeth, runout and belt dimensions.

7. Zhejiang Haitukai Rubber Belt Co., Ltd. – Best for Special Belt Configurations

Company Background

Zhejiang Haitukai Rubber Belt Co., Ltd. operates in Sanmen County, Taizhou, an area with a long rubber belt manufacturing base. Its catalog includes industrial rubber synchronous belts, automotive belts, pulleys, PU belts, multi-rib belts, V-belts and flat belts.

Product Line

Haitukai publishes several unusual timing belt categories, including single-sided, double-sided, open-tooth, thickened-tooth and special-tooth products. This range can be useful for legacy equipment or machinery that uses a modified belt geometry not covered by common distributor inventories.

Special product names do not fully define the construction. Buyers should provide a physical sample or controlled drawing showing pitch, tooth shape, backing thickness, total height, width and tensile-member position. A thickened or modified tooth can require a matching pulley and may not be interchangeable with a standard belt sharing the same pitch.

Why We Recommend It

Haitukai is a reasonable candidate for uncommon replacement and custom configurations, but its English technical documentation is limited. Begin with a small qualification order and request dimensional reports. If the application is critical, verify the factory, tooling and inspection process before committing to a large production batch.

8. Shaoxing CSHBELT Co., Ltd. – Best for General Industrial Timing Belt Supply

Company Background

Shaoxing CSHBELT Co., Ltd. is located in Shengzhou, Zhejiang and manufactures rubber and polyurethane belts. Its range includes rubber timing belts, special timing belts, pull-down products and timing pulleys. The company states that it uses dedicated production management and testing equipment for its belt programs.

Product Line

CSHBELT can be considered for general industrial synchronous drives and custom projects that do not require the scale of a large diversified group. Its mixed rubber, polyurethane and pulley offering may help distributors source several related transmission components from one company.

Public information confirms relevant product categories but provides fewer detailed belt tables than some higher-ranked manufacturers. Buyers should ask for the exact compound, cord, fabric, profile standard and dimensional tolerance. A company-level quality claim is less useful than a specification and inspection report tied to the quoted belt.

Why We Recommend It

CSHBELT is best suited to buyers willing to qualify products through samples and documentation. When requesting a special belt, define whether the modification is molded, bonded or machined after vulcanization. These production routes can produce different limits for adhesion, flexibility and repeatability.

9. Xingtai Huanning Rubber Products Co., Ltd. – Best for Standard Rubber Belt Replacement

Company Background

Xingtai Huanning Rubber Products Co., Ltd. manufactures a broad selection of rubber transmission belts in Xingtai, Hebei. Its products include synchronous belts, multi-rib belts, cut and wrapped V-belts, variable-speed belts and special double-sided products. The company also describes a multi-location warehouse network for standard inventory.

Product Line

The broad rubber range makes Huanning a possible source for common replacement belts and distributor stock. Warehouse availability can shorten lead times, but buyers must distinguish stocked products from belts made specifically by the quoted factory. Production entity, batch traceability and construction should remain clear on purchase documents.

Huanning publishes less detailed technical information than the higher-ranked companies. It is therefore better suited to standard dimensions than precision custom applications unless additional evidence is supplied. Request profile drawings, compound information, width and length tolerances, and the inspection method used for finished belts.

Why We Recommend It

For an inventory order, approve samples from the same brand and construction that will be shipped in volume. A visually similar substitute can use a different cord or rubber formulation. Labeling and lot identification should be agreed in advance so repeat shipments remain comparable.

10. Xiamen Hee Industrial Belt Co., Ltd. – Best for Combined Timing and Conveyor Belt Sourcing

Company Background

Xiamen Hee Industrial Belt Co., Ltd. markets industrial belts under the XINBEX name. Its broad offering includes rubber and polyurethane timing belts, PVC and PU conveyor belts, special conveyor belts, transmission belts and belt-processing equipment. This range may appeal to buyers consolidating several light industrial belt categories.

Product Line

The company describes timing belt manufacturing and OEM support for industrial and power-transmission applications. It also publishes information about custom projects and combined belting solutions. However, its public material contains more extensive detail for conveyor and polyurethane products than for specific rubber timing belt constructions.

This difference does not disqualify Xiamen Hee, but it warrants a lower ranking and stronger product verification. Buyers should request rubber-specific production evidence, compound and cord details, tooth-profile drawings, factory information and representative samples. General conveyor belt certifications should not be assumed to cover a rubber synchronous belt.

Why We Recommend It

Xiamen Hee is most suitable when an equipment builder needs timing and conveyor products through one commercial contact. The benefit of consolidated sourcing should not replace technical approval. Each belt category needs its own drawing, material requirements, inspection criteria and traceability.

How Were These Rubber Timing Belt Manufacturers Evaluated?

Candidates needed an identifiable Chinese company and operating location plus public evidence of rubber timing belt production or a stated synchronous-belt manufacturing role. Companies focused only on heavy conveyor belts, V-belts or automotive replacement trading were not treated as industrial rubber timing belt manufacturers without additional evidence.

The evaluation considered industrial profile coverage, single- and double-sided construction, compound and reinforcement information, special processing, pulley support and technical transparency. International communication and OEM capability also influenced practical purchasing value. Companies with limited public product detail were retained only when they showed relevant manufacturing activity and were ranked lower.

No customer ratings, test scores or performance awards were invented. Factory statistics and product claims remain manufacturer-provided unless supported by independent evidence. TranBelt’s position includes the publisher’s commercial perspective and is disclosed accordingly. Buyers should apply identical drawing, sampling, inspection and warranty requirements to TranBelt and every competing manufacturer.

What Should You Compare When Choosing a Rubber Timing Belt Manufacturer?

A useful quotation must define more than profile and length. Rubber timing belts combine a molded elastomer, tensile reinforcement and tooth-facing fabric into one working structure. Changes in any layer can alter stiffness, heat resistance, elongation, tooth wear and fatigue life, even when the external dimensions appear identical.

Rubber Compound

Chloroprene, often called neoprene, is widely used in industrial timing belts because it balances flexibility, wear and environmental resistance. EPDM and application-specific compounds may be selected for different temperature, ozone or aging requirements. The material should be chosen against actual operating conditions rather than a general statement that one rubber is superior.

Ask the manufacturer to identify the compound family and its intended operating limits. Oil, chemicals, ambient heat and repeated flexing can affect rubber differently. If exposure is uncertain, provide the fluid name, concentration and temperature. A compound used successfully in a dry packaging machine may not suit an oily machine-tool environment.

Tensile Cord and Tooth Fabric

The tensile cord controls belt length and carries working tension. Fiberglass is common in molded rubber timing belts, while aramid or other reinforcements may be used for specialized requirements. Cord material, twist, position and bonding influence elongation, flexibility and resistance to repeated bending.

Tooth-facing fabric protects the rubber during pulley engagement and can reduce friction and noise. Buyers should specify fabric requirements when replacing a proven belt or qualifying a critical drive. Poor adhesion between rubber, cord and fabric can cause tooth separation even when the visible rubber surface initially appears acceptable.

Tooth Profile and Belt Dimensions

Nominal pitch does not establish interchangeability. HTD, STD and RPP belts can share a pitch number while using different tooth geometry. T and AT profiles also differ in tooth form and load behavior. Match the full designation to the pulley and confirm the standard applied by the manufacturer.

Specify pitch length, width, tooth count, total thickness and tolerance. TranBelt’s timing belt pitch guide can help identify an old belt when markings are missing. For a new design, use pulley and load data rather than selecting a belt from width alone.

Endless Construction and Double-Sided Belts

Industrial rubber timing belts are commonly molded and vulcanized into an endless loop. This construction differs from joined thermoplastic belts and should not contain a welded splice. Verify whether very long or unusual belts use the same endless manufacturing method as standard sizes.

Double-sided belts may use symmetrical teeth or different tooth relationships depending on the profile. They can drive shafts from both surfaces, but reverse bending increases fatigue demands. Specify the pulley arrangement, wrap direction and minimum diameters so the manufacturer can confirm that the construction suits the drive.

Coatings and Custom Processing

Rubber and sponge backings can increase grip, cushion products or compensate for shape. Grinding controls thickness, while holes, grooves and tooth removal can support vacuum transport and fixtures. These modifications are common in packaging and conveying but can weaken a belt if machining approaches the tensile cords.

Define coating material, hardness, thickness and bond method. Drawings should show critical dimensions and protected cord zones. Approve a fully processed sample rather than an uncoated base belt. The manufacturer should also confirm the minimum pulley diameter because a thick backing increases bending strain.

Quality and Supplier Verification

Confirm the legal company, production location and scope of work completed internally. A supplier may manufacture the base belt but subcontract coating or machining. That arrangement can be acceptable when drawings, materials, inspection and corrective action remain controlled across the complete process.

Request a signed drawing, material specification, dimensional report and production-representative samples. Critical orders may require tensile, adhesion, fatigue or compound test data. Define branding, batch labels, packaging, traceability and warranty terms before production so future shipments can be compared with the approved construction.

Frequently Asked Questions

What Is a Rubber Timing Belt?

A rubber timing belt is an endless toothed belt that engages a matching pulley without intentional slip. Its molded rubber body contains tensile cords that control length and carry load, while fabric commonly protects the teeth. Rubber timing belts synchronize shafts in industrial machinery, engines, packaging equipment and other power-transmission systems.

What Rubber Is Used in Industrial Timing Belts?

Chloroprene is common because it offers a useful balance of flexibility, wear and environmental resistance. EPDM and specialized compounds may be used when temperature, ozone, oil or chemical exposure changes the requirement. The correct material depends on the complete construction and operating environment, not only the rubber name.

Are Rubber Timing Belts Better Than PU Timing Belts?

Rubber belts often provide good flexibility, damping and high-speed behavior, while polyurethane belts offer clean operation, wear resistance and extensive processing options. Neither material is universally better. Compare load, pulley diameter, temperature, chemicals, positioning accuracy and whether the application needs a molded endless, open-ended or welded construction.

Can a Rubber Timing Belt Be Custom Coated?

Yes. Manufacturers can add rubber, sponge, fabric and other backings or create molded profiles for product handling. Coated belts may also be ground, drilled or grooved. The backing changes flexibility and minimum pulley requirements, so buyers should approve a finished sample produced with the actual coating and machining process.

What Information Should a Rubber Timing Belt RFQ Include?

Provide the complete profile, pitch length, width, tooth count, compound, cord and tooth-fabric requirements. Add pulley diameters, load, speed, temperature and chemical exposure. For custom belts, include coating hardness and thickness plus drawings for holes, grooves, cleats or removed teeth. Photos and an old sample help when markings are unreadable.

Conclusion

The best China rubber timing belt manufacturer depends on the required profile, compound, reinforcement and processing. Standard power-transmission belts, double-sided drives and coated handling belts demand different production strengths. Buyers should also distinguish industrial constructions from automotive-only products that happen to share a similar designation.

TranBelt manufactures standard and OEM rubber timing belts in Shenzhen while also supplying leading imported brands at distributor-oriented prices. The other companies in this review offer different strengths in established production, profile coverage and custom processing. Whichever manufacturer you choose, approve a controlled drawing and production-representative sample before committing to volume orders.
