Top 10 China Industrial Timing Belt Suppliers (2026 Reviews)

Home » Timing Belt » Top 10 China Industrial Timing Belt Suppliers (2026 Reviews)

Quick Link

China has many industrial timing belt suppliers, but their capabilities are not interchangeable. Some mold rubber synchronous belts at scale, some specialize in polyurethane belts for automation, and others combine manufacturing with distribution. Buyers therefore need to compare product fit, technical support, customization, and supplier identity rather than treating the lowest quotation as the best offer.

This 2026 review uses public company records, official product information, and industry listings. It is not a substitute for a factory audit or sample test. TranBelt publishes this article and appears in the ranking, so that commercial relationship is disclosed. The reviews focus on verifiable sourcing characteristics, not invented customer ratings or unconfirmed performance claims.

Top 10 Industrial Timing Belt Suppliers in China

The following reviews separate documented product scope from purchasing judgment. A high position reflects breadth, industrial relevance, export accessibility, or public technical evidence. It does not guarantee that one supplier’s belt will outperform another in a specific drive. Final selection must follow the machine design, operating conditions, sample results, and commercial verification.

1. TranBelt — Best Overall for International Buyers

Based in Shenzhen, Guangdong, TranBelt uses a dual supply model. It offers high-quality imported industrial timing belts from Gates, Continental, Bando, Megadyne, Mitsuboshi, Optibelt, and other established brands at distributor-level pricing. It also supplies its own high-quality OEM timing belts for standard replacement, custom specifications, and private-label programs.

TranBelt’s rubber and polyurethane timing belts are available with profiles, coatings, V-guides, carriers, vacuum holes, and related accessories. The range includes metric and imperial profiles, open-ended PU belts, molded or endless designs, and rubber RPP belts. TranBelt also offers pulleys, clamping plates, tension rollers, and machined drive components.

The practical advantage is choice. A distributor can compare an original imported belt with a TranBelt OEM alternative while keeping pulleys and custom processing within the same inquiry. This approach suits buyers managing mixed brands, obsolete references, several price levels, or private-label requirements. It is less relevant when a procurement policy permits only direct purchases from a named brand owner.

TranBelt publishes this article, so its first-place position is not independent. Its business combines manufacturing, OEM/ODM, brand representation and engineering support, supported by partnerships with more than ten belt manufacturers. Buyers should separate imported, partner-produced, and in-house OEM items on the quotation, then verify brand authorization, certificate scope, warranty, stock status, and sample traceability.

2. Ningbo Fulong — Best for Established Rubber Belt Manufacturing

Founded in 1984, Ningbo Fulong Synchronous Belt Co., Ltd. has the strongest publicly documented manufacturing history in this group. The company reports a CNAS laboratory, standards participation, patents, and technical centers. Its product coverage extends across industrial and automotive rubber belts, PU timing belts, poly-V belts, variable-speed belts, pulleys, and other transmission products.

Fulong manufactures single-sided, double-sided, coated, open-ended, and high-torque belts. Available profiles include classical MXL through XXH, T and AT, HTD, STS, RPP, and MR. Fulong reports access to more than 8,000 molds, although buyers should treat that figure as unverified until it is supported by a mold list or factory audit.

Fulong provides unusually detailed PU timing belt specifications, distinguishing open, connected, and seamless constructions. Width, length, thickness, and load data are available for several profiles, while matching pulleys can be made from steel, aluminum, cast iron, or nylon. This level of detail helps engineers screen options before requesting a formal calculation.

Fulong is a strong candidate for OEM and distributor programs requiring broad rubber coverage, technical records, and an established legal identity. The limitation is that online tables remain supplier data, not independent performance testing. Buyers should verify current certificates, compound and cord origin, mold condition, production tolerances, test methods, batch traceability, and whether the quoted belt is molded, cut from a sleeve, welded, or subcontracted.

3. Zhejiang Jiaoma — Best for Rubber and PU Timing Belt Variety

Zhejiang Jiaoma Timing Belt Co., Ltd. has produced timing belts since 1994 and covers design, development, production, inspection, and custom engineering. Its portfolio includes trapezoidal, curvilinear, double-sided, open-ended, rubber, and polyurethane belts for textiles, food equipment, printing, woodworking, logistics, robotics, and other machinery.

Jiaoma provides more dimensional detail than many smaller suppliers. Its molded PU timing belts cover T, AT, XL, L, H, XH, HTD, STD, and RPP families, with widths from 3 to 250 mm and published lengths from 120 to 4,780 mm. Steel cords are standard, while aramid is available as an option.

Its open-ended range distinguishes chloroprene rubber from thermoplastic PU construction. Jiaoma states that spiral-cut rubber open belts are limited to widths below 25 mm, while its PU open belts can reach 150 mm and can be joined. That specificity is useful because it exposes process limits rather than presenting every construction as equivalent.

Jiaoma is suitable for buyers comparing several tooth families, materials, pulleys, and linear-motion products. Its quality, patent, response-time, and certification claims have not all been independently verified. Buyers should confirm the latest certificate scope, actual mold availability, cord supplier, joining method, dimensional inspection, and whether published size limits apply to the precise material and profile being quoted.

4. Shaoxing CSH Belt — Best for Drive, Linear Motion and Conveying

Shaoxing CSHBELT Co., Ltd. has produced industrial rubber and polyurethane timing belts since 2007, focusing on power transmission, linear motion, and synchronous conveying. The company identity and address also appear in industry exhibition records, supporting an active commercial presence beyond its own marketing materials.

CSH’s rubber timing belts include classical, T, AT, HTD, S, and RPP families. The described construction combines chloroprene, glass-fiber cords, and nylon tooth fabric. Separate rubber open-ended belts use spiral-cut production and target automatic doors, CNC equipment, printers, and other linear-motion systems.

CSH offers PU open-ended and welded belts with multiple profiles, coatings, and fabricated options. The jointed constructions are intended primarily for conveying and indexing. Buyers should not apply published speed, temperature, or resistance values to every belt without confirming the profile, cord, joint, width, and test conditions.

CSH is best suited to machine builders needing both rubber power-transmission belts and PU linear or conveying products. Its online technical range is useful, but buyers still need drawings and production-specific evidence. Confirm whether a belt is truly endless, sleeve-cut, spiral-cut, extruded, or welded, then request joint-strength data, dimensional tolerances, pulley requirements, material declarations, and representative samples.

5. Foshan Xinzhen — Best for Polyurethane Timing Belts

Foshan Xinzhen Industrial Belt Co., Ltd. is the most narrowly focused polyurethane specialist in the ranking. It produces PU timing belts, synchronous pulleys, and specially processed products for ceramics, glass, woodworking, food, packaging, printing, metalworking, textiles, automation, logistics, and transportation.

Xinzhen’s custom polyurethane timing belts include open-ended HTD belts, connected T-series belts, ATN products with mechanical attachments, welded stoppers, backing materials, tooth fabrics, grooves, and other fabricated features. This range is more relevant to automation and product handling than one limited to plain endless power-transmission belts.

Xinzhen is a reasonable shortlist candidate for PU belts requiring cleats, guides, coatings, machining, or application-specific fabrication. Independent evidence of its manufacturing capabilities is more limited than for Fulong or Yongli Kaibo. Buyers should verify the Chinese legal entity, production address, equipment, certificate scope, material source, cord type, joint efficiency, inspection methods, and a sample made through the proposed production route.

6. Ningbo FRK Power — Best for Broad Profile and Coating Options

Ningbo FRK Power markets rubber timing belts, TPU open-ended belts, molded and joined PU belts, coated belts, double-sided profiles, ribbed belts, V-belts, flat belts, and pulleys. Target applications include textiles, machine tools, printing, packaging, food equipment, appliances, petrochemicals, and other mechanical drives.

FRK separates trapezoidal and curvilinear rubber belts from TPU open-ended, CPU endless, PU joined, coating, and pulley products. This structure helps buyers compare several constructions, but the available technical detail varies by product. A long list of profiles is not the same as documented mold ownership, production capacity, or proven performance under a given load.

FRK is most useful for buyers seeking broad profile coverage and several secondary-processing options through one sales contact. It is not clear which processes occur within the contracting entity and which may involve partner production. Until that relationship is verified, FRK should be treated as a supplier rather than automatically described as a fully integrated factory.

Request the Chinese legal name, invoice entity, production address, process map, subcontracting disclosure, current certificates, available mold list, coating specification, and inspection plan. Samples should come from the proposed production route. This review does not rely on the company’s published growth rate or export reach because those claims were not independently verified.

7. Shanghai Yongli Kaibo — Best for Engineered PU Belt Solutions

Shanghai Yongli Kaibo Transmission System Co., Ltd. supplies polyurethane timing belts, rubber timing belts, pulleys, traction steel belts, flat belts, and processed accessories for automation, new energy equipment, semiconductors, food processing, elevators, textiles, logistics, and other industrial systems. The emphasis is broader system engineering rather than only selling catalog belt sizes.

Its product pages make an important limitation unusually explicit. For several joined thermoplastic PU timing belts, Yongli Kaibo states that the joint retains about 50% of the belt-body strength and that the joined construction is intended only for conveying. This disclosure helps buyers avoid specifying a welded conveying belt for a high-load power-transmission application.

The company also shows backing fabrics, added PU, profiles, guides, and other application-specific constructions. This makes it relevant when the belt must handle, position, grip, or transport a product. Buyers should separate those functions from synchronous torque transmission and request the permissible tension, pulley diameter, joint factor, cord construction, backing adhesion, and test basis for the exact build.

Corporate identity is unusually transparent for this list. Yongli Kaibo is associated with Shenzhen-listed Yongli, and public registration and financial information are available through the exchange. That strengthens corporate due diligence, but it does not replace technical approval. Buyers still need production-specific drawings, samples, tolerances, certificate scope, and application testing.

8. Zhejiang INJ Transmission Systems — Best for Mixed Belt Procurement

Zhejiang INJ Transmission Systems Co., Ltd. markets LSL rubber and PU timing belts alongside V-belts, poly-V belts, round belts, flat belts, agricultural belts, automotive belts, and pulleys. Available timing belt families include HTD, S, MXL, XL, L, H, XH, AT, and T plus open-ended, coated, and special PU constructions.

INJ positions itself toward distributors and repeat export programs. The site describes samples, mixed-size trial orders, OEM branding, private-label packaging, and FOB China supply. That commercial flexibility is useful when a buyer needs several belt families in one program. It is less important for an engineer purchasing one highly specialized belt whose technical validation matters more than range.

The product range also includes molded or welded guides, PAZ or PAR tooth fabric, rubber, APL, and PU coatings. These options can support tracking and material handling, but their published descriptions do not establish performance for every application. The buyer should request a drawing showing the guide geometry, joint, backing, cord path, width, and allowable lateral load.

INJ is an established legal business, but the extent of its in-house production across every product category has not been independently confirmed. Buyers should verify the factory address, process ownership, mold control, material traceability, inspection records, and sample origin. Mixed procurement is an advantage only when each product remains traceable to its actual production route.

9. Sanmen Binlong — Best for Heavy-Duty Rubber Timing Belts

Sanmen Binlong Transmission Belt Co., Ltd. began operations in 2008 and serves automotive, agricultural, mining, engineering, textile, construction, and other power-transmission applications. The company name and Chinese address also appear in public trademark records, supporting the existence of the operating business.

Binlong stands out for a heavy-duty carbon-cord rubber timing belt rather than only generic profile lists. The construction combines an HNBR body with a carbon tensile member and covers HTD 8M, 11M, and 14M plus STD 8M and 14M dimensions. It targets high torque, shock, temperature, and heavy-load service.

Those specifications make Binlong worth screening for compact or high-load rubber drives, but no independent comparative test was found to confirm the advertised performance. Buyers should request rated-power tables, fatigue-test methods, pulley limits, tooth-shear data, cord adhesion results, temperature range, service factor, and evidence that the production belt matches the tested construction.

Binlong may be less suitable when a project primarily requires fabricated PU conveying belts, welded cleats, or extensive clean-process documentation. Its strongest fit is rubber power transmission. As with every shortlisted company, confirm certificate validity, material batch control, production site, mold ownership, inspection capability, and production-representative samples.

10. Foshan Uliflex — Best for Custom PU Belts and Belt Systems

Foshan Uliflex Transmission Technology Co., Ltd. offers open-ended PU, rubber, endless PU, and molded PU power belts alongside profiled belts, fabricated belts, conveyor belts, and application-specific processing. Its target markets include glass, ceramics, textiles, food equipment, elevators, packaging, and industrial automation.

Customization is the company’s clearest differentiator. Uliflex supports rubber, PU, foam, sponge, patterned, and nylon backings plus finger joining, cleats, notching, grinding, and perforating. These processes suit product handling and positioning, where surface behavior and attachment geometry can matter as much as tooth profile.

Uliflex also describes truly endless PU belts with continuous steel or aramid cords. Buyers should distinguish those from finger-welded belts because the manufacturing route changes permissible load and duty. Request confirmation of cord continuity, joint type, profile standard, backing adhesion, cleat weld method, minimum pulley diameter, and whether technical values refer to the base belt or the finished fabricated product.

Uliflex reports patented equipment and technical design support, while exhibition records support an active industry presence. Its performance and delivery claims have not all been independently verified. Buyers should confirm the Chinese legal entity corresponding to the Uliflex name, invoicing company, production address, certificate scope, patent relevance, inspection plan, and production-representative sample.

How Were These Industrial Timing Belt Suppliers Evaluated?

The ranking considered six practical factors: evidence that the business exists, industrial timing belt relevance, product breadth, custom processing, technical information, and accessibility to international buyers. Official company pages established current product scope. Corporate filings, government documents, public registration information, and exhibition directories were used where available to strengthen identity checks.

Evidence quality differs by supplier. Fulong and Yongli Kaibo have stronger public institutional records, while several smaller companies are documented mainly through their websites and trade presence. That does not prove inferior products, but it increases the buyer’s verification burden. Supplier, manufacturer, and brand are therefore used deliberately rather than as interchangeable labels.

This is a sourcing review, not a controlled belt test. No products were ranked through identical laboratory conditions, and no unverified customer scores were used. TranBelt publishes the article and is included in it. Its first-place position reflects broad international procurement support and product coverage, not a claim of independently proven superiority over every listed manufacturer.

How Do You Choose the Right Chinese Timing Belt Supplier?

Start with the drive specification, not a supplier name. State the tooth family, pitch, pitch length or tooth count, width, belt material, tensile member, construction, pulley data, speed, torque, center distance, and operating environment. TranBelt’s guide to measuring timing belt pitch explains why equal pitch does not guarantee compatible tooth geometry.

Define whether the belt must be molded endless, open-ended, welded, or mechanically joined. A joined PU belt may work well for synchronized conveying but may not carry the same tension as a molded endless power-transmission belt. Specify coatings, backing thickness, cleats, perforations, grinding, antistatic behavior, food contact, temperature, chemicals, and cleanliness requirements when relevant.

Send the same request for quotation to shortlisted suppliers. Compare drawing confirmation, material declaration, tolerances, inspection plan, tooling ownership, sample cost, minimum quantity, production lead time, packaging, Incoterms, and corrective-action process. A quotation that omits construction or inspection details is difficult to compare, even when its unit price appears attractive.

Verify the legal company name against the bank account, invoice, export documents, and contract. Ask whether each operation is performed in-house or subcontracted. For important programs, use a video inspection or independent audit and test production-representative samples on the intended pulleys. Calculate operating requirements before approval; the timing belt drive calculation guide covers the main definitions needed for a technical discussion.

Frequently Asked Questions

Are industrial timing belts from China reliable?

Chinese suppliers produce belts across many quality and price levels. Reliability depends on correct profile selection, compound, tensile cords, tooth molding, dimensional control, storage, and application design. Country of origin alone cannot predict service life. Verify the specification, test representative samples, and approve the actual production construction before committing to volume.

How can you verify a Chinese timing belt supplier?

Confirm the registered company, address, bank account, invoice entity, export capability, and certificate scope. Review live production or use an independent audit when risk justifies it. Ask which processes are internal, obtain drawings and inspection records, and test samples. A professional website supports discovery, but it does not by itself prove factory ownership.

What information should a timing belt RFQ include?

Provide tooth profile, pitch, tooth count or pitch length, width, material, cord, pulley tooth counts, speed, torque, center distance, environment, quantity, and required processing. Add photographs and the existing marking when replacing a belt. State the acceptance method so the supplier knows which dimensions, materials, and performance records must accompany the sample.

Should you request samples before placing a bulk order?

Yes, especially for custom compounds, coatings, joined belts, fabricated profiles, or critical drives. A catalog sample can confirm communication and basic dimensions, but it may not validate the final construction. Request a production-representative sample or pilot batch, inspect it against the approved drawing, and test it under realistic tension, load, pulley, and environmental conditions.

Conclusion

The best China industrial timing belt supplier depends on the belt construction and purchasing model. TranBelt provides broad international sourcing, Fulong offers strongly documented rubber belt manufacturing, Xinzhen concentrates on polyurethane products, and Yongli Kaibo supports engineered systems. The other suppliers add useful profile, processing, and multi-category options.

Treat this list as a qualified shortlist rather than a purchase approval. Send a complete specification, verify the contracting and production entities, inspect representative samples, and compare technical evidence alongside landed cost. TranBelt can review belt markings, drawings, pulley data, and application conditions before preparing a quotation.
