Quick Answer Yes. We routinely manufacture custom timing belts to match Gates, Continental ContiTech, Bando Chemical, and Mitsuboshi Belting specifications — either from your controlled drawing, an OEM part number, or a physical sample we reverse-engineer in our lab. Your own drawing, inspection criteria, and approved material stay on file, every production batch ships with a full traceability dossier, and lead times for cross-reference samples run 7 to 12 working days, with production batches at 10 to 18 working days. Why This Question Comes From North American and European Buyers Most industrial OEMs in the United States and the European Union are explicitly audited on supply-chain resilience. After the post-2020 disruptions, many procurement and quality teams told us the same thing: “We love Gates on the print, but if Gates allocates to a German automotive customer first, our line stops. We need a second qualified source that builds the exact same belt.” Our cross-reference program is the answer to that brief. Build-to-print from your controlled drawing and BOM, with full revision control. Reverse-engineering from a worn belt sample — we measure pitch, width, tooth profile, hardness, and tensile strength in-house. You keep the master drawing. Tooling, drawings, and inspection criteria are contractually tied to your part number, not ours. Standards compliance to ISO 13050, DIN 7721, DIN 7753, ANSI B29.1, and RMA IP-23 for both metric and imperial pitches. Documentation for your supplier audit — ISO 9001, RoHS, REACH, FDA (where required), and per-batch tensile / elongation / dimensional reports. How We Match a Major-Brand Specification Our engineering follow-up is the same whether you give us a Gates Hi-Power or PowerGrip GT part number, a Continental ContiTech Synchrochain or Synchrobelt reference, a Bando specification sheet, or a Mitsuboshi polychain / timing belt datasheet. Specification lock — we capture tooth profile, pitch, number of teeth, belt width, tensile cord material (fiberglass, aramid, steel), compound (CR, HNBR, EPDM, PU, silicone), and any surface treatment. Reverse-engineering (if no drawing exists) — 3D-scanned tooth geometry, Shore-A hardness, tensile testing, and a side-by-side comparison with the original Gates / Continental / Bando / Mitsuboshi sample if you can supply one. First-article inspection (FAI) — signed FAI report attached to your drawing so your quality team can release the part on their PPAP or IMDS workflow. Production retention — cure date, cord lot, compound lot, and dimensional inspection data archived for at least seven years for future re-orders and emergency restocks. Standards and Cross-Reference Coverage We build to the standards that your European and US engineers actually quote on drawings. Metric profiles HTD 3M / 5M / 8M / 14M / 20M, STD S3M / S5M / S8M / S14M, T5 / T10 / T20, AT5 / AT10 / AT20, and RPP5 / RPP8 are produced to ISO 13050 and DIN 7721. Imperial profiles XL, L, H, XH, XXH, and 40DP follow RMA IP-23 and ANSI B29.1. Tooth-to-pulley fit, center-distance tolerance, and elongation behavior are validated against the original brand sample before sign-off. What We Need From You to Start Send any of the following and our applications team responds within 24 hours with a sample price and production estimate: Your current Gates / Continental / Bando / Mitsuboshi part number, or your own OEM drawing. A worn or unused sample of the existing belt (we return it with the prototypes). Application details — drive geometry, peak load, RPM, ambient temperature, contamination, and any chemical exposure. The compliance target your end customer expects (RoHS, REACH, FDA, UL, automotive IMDS). Single-Source Risk: Our Recommended Buyer Workflow For US and EU procurement teams running formal dual-sourcing programs, we recommend a three-step engagement: first a small validation batch against your existing brand sample, then a side-by-side run for one quarter on a non-critical line, and finally dual release with retained tooling at our facility and full drawing control on your side. This sequence lets your quality team qualify the belt without putting a critical line at risk. Forward your current OEM part number or drawing and you will receive a quote, lead time, and a side-by-side comparison plan within one business day.

Quick Answer For a custom timing belt, our prototyping MOQ is as low as 10 pieces per specification, and production orders usually start at 50 to 100 pieces depending on tooth profile, width, and material. Custom samples are typically dispatched in 5 to 7 working days when tooling already exists and 7 to 12 working days when a new mold, die, or grinding fixture is required. Mixed-specification sample orders are accepted so you can test several candidates in one shipment, and the sample cost is rebated against your first production purchase order. Why MOQ and Sampling Matter to US and European Buyers In conversations with North American OEMs and European machine builders, three frustrations come up repeatedly: being forced to buy 500 pieces of a custom belt just to validate a redesign, paying for samples that never get refunded, and waiting three to four weeks for a part that is supposed to be a quick iteration. Our sampling program was built around removing exactly these friction points. Prototyping MOQ from 10 pieces — enough material to machine-mount, run a pilot shift, or send to your lab for material certification. Sample lead time 5–7 working days from existing tooling, with 7–12 days for new custom molds and extruder calibrations. Mixed SKUs in one sample shipment — validate several widths, profiles, or compounds in a single purchase order. Sample-cost rebate against your first PO, so the prototype is not a sunk cost. Test report included with every sample shipment: tensile strength, elongation, Shore hardness, and dimensional inspection. What You Need to Send Before We Quote a Sample To convert a sample request into an accurate quote within 24 hours, share these five points with our engineering team: Belt specification — tooth profile and pitch (HTD, STD, T, AT, RPP, Imperial RMA), belt length, width, and number of teeth. Material and reinforcement — chloroprene rubber (CR), hydrogenated nitrile (HNBR), EPDM, polyurethane (PU), silicone; fiberglass, aramid / Kevlar, steel, or polyester tensile cord. Application context — operating temperature, peak torque, RPM, chemical or oil exposure, food / pharmaceutical / outdoor environment. Pulley data — number of teeth, flange style, center distance, keyway, or a sample of the existing pulley. Compliance target — RoHS, REACH, FDA, UL, or specific OEM cross-reference such as Gates, Continental ContiTech, Bando, or Mitsuboshi part numbers. What Happens After You Approve the Sample Mass-production lead time typically runs 10–18 working days after sample approval, depending on batch size and reinforcement. Ocean freight to US ports (Los Angeles, New York, Houston) usually adds 12–18 days; air freight is available for urgent lines in 5–7 days. Every production batch carries 100% dimensional inspection plus batch-level tensile and Shore-A testing, and a full traceability dossier (material lot, cord lot, cure date, QC signature) is shipped with the goods. Common Buyer Questions We Hear Can I get a free sample? We provide free samples for stock-style custom specifications; for unique compounds or new tooling, a small sample fee applies and is fully rebated on the first production PO. Do you ship samples via DHL / FedEx? Yes — we routinely ship sample parcels via DHL, FedEx, UPS, or TNT for North American and EU destinations, typically arriving in 3–5 business days. Can you sign an NDA before I share drawings? Absolutely. Our legal team routinely countersigns mutual NDAs and confidentiality agreements so that your drawings, bills of material, and proprietary dimensions stay protected. Send your drawing, sample, or specification to our engineering team and you will receive a fixed-price sample quote within 24 hours.

KEY TAKEAWAY A sponge timing belt is a synchronous belt with a foam layer bonded to its outer surface, designed to provide cushioning, grip, and noise absorption for transporting delicate or irregularly shaped products without damage. Sponge timing belts combine the precision of synchronous drive with the protective cushioning of a foam surface. The foam layer — typically PU, silicone, or rubber sponge — provides a compliant interface that conforms to product surfaces, absorbs impact, and distributes contact pressure evenly.

KEY TAKEAWAY Vulcanization creates three-dimensional crosslinks between polymer chains, dramatically increasing tensile strength, wear resistance, heat stability, and permanent deformation resistance. Discovered by Charles Goodyear in 1839, vulcanization transforms raw rubber from a plastic, easily deformable state into an elastic, durable engineering material. In rubber vulcanization, sulfur atoms form disulfide (S-S) and polysulfide bridges between adjacent polymer chains.

What are the advantages of rubber timing belts over other belt types? What is a timing belt and how does it work in power transmission systems?

KEY TAKEAWAY A silicone vulcanized timing belt is manufactured through a heat-and-pressure chemical crosslinking process that permanently bonds the silicone layer to the belt body, creating a monolithic structure with superior peel resistance, longer service life, and better dimensional stability. The vulcanization process fundamentally transforms silicone from a thermoplastic state into a thermoset structure through covalent crosslinking between polymer chains. In timing belts, this means the silicone cover layer becomes chemically integrated with the underlying belt substrate rather than merely glued on.

KEY TAKEAWAY Silicone timing belts maintain flexibility, dimensional stability, and mechanical integrity at continuous operating temperatures up to 200°C, far beyond the limits of standard rubber (120°C) or PU (80°C) belts. Silicone timing belts are engineered specifically for thermal extremes where conventional belt materials would degrade, embrittle, or melt. The key differentiator is the silicone polymer's unique siloxane (Si-O) backbone, which provides inherent thermal stability that carbon-based polymers cannot match.

KEY TAKEAWAYA timing belt is a synchronous power transmission belt with evenly spaced teeth on its inner surface that mesh precisely with matching pulley grooves, ensuring zero-slip, constant-speed power transfer between rotating shafts.How It WorksTiming belts (synchronous belts) operate on positive tooth engagement rather than friction. Unlike V-belts or flat belts, timing belts use precisely molded teeth to engage with pulley grooves, eliminating slippage entirely.The belt has three key layers:Toothed body — Rubber or PU material for flexibility and tooth form retention.Tensile cord — Fiberglass, steel, or Kevlar fibers embedded in the neutral axis to carry load without stretching.Fabric facing — Durable nylon coating on the tooth surface to reduce wear and noise.Common Tooth ProfilesProfileTypeBest ForTorque CapacityMXL, XL, L, H, XHTrapezoidalGeneral industrial drivesLow-MediumHTD, STDCurvilinearHigh-torque applicationsHigh (up to 1000 Nm)GT, GT2, GT3Modified CurvilinearPrecision positioningMedium-HighHTD profiles feature a deeper, rounded tooth form for better stress distribution.

To get a quotation, you can send us the belt size, drawing, sample photo or machine model.For standard belts, we can quote based on tooth profile, length, width and quantity. For customized belts, we also need to confirm surface coating, holes, grooves, guide strips, hardness and working environment.The price of a vulcanized timing belt depends on material, size, production process, customization level and order quantity. A simple standard belt is usually faster and more economical. A belt with special coating, precise holes or complex processing may need more production time.GOODLY is an industrial belt manufacturer with custom production capability. Whether you need one sample for testing or bulk order for production, we can provide a suitable solution based on your machine requirements.Contact GOODLY and send your belt size, drawing or sample photo. We will help you choose the right vulcanized timing belt for your machine.

Yes. Vulcanized timing belts are widely used in packaging machines, especially where stable film feeding, accurate positioning and long running time are required.In packaging equipment, a small belt problem can cause bigger production issues. For example, if the pulling belt slips or wears, the bag length may become unstable. If the belt surface grip is not enough, film feeding may be inaccurate. If the belt joint is weak, the machine may stop unexpectedly.For packaging machines, GOODLY can customize vulcanized timing belts with high-grip surface, holes, grooves, rubber backing, PU coating or special hardness. These designs help improve machine stability and reduce production downtime.Common applications include VFFS machines, horizontal packaging machines, sealing machines, labeling machines, cartoning machines and automatic feeding systems.

The most common causes are wrong tension, poor pulley alignment, overload, unsuitable material, high temperature, sharp contact points or weak joint quality.If the belt breaks at the joint, it may mean the joint strength is not enough for your application. In this case, a vulcanized timing belt may be a better solution.If the tooth surface wears quickly, you should check whether the pulley is worn or whether the belt tooth profile matches the pulley.If the belt edge is damaged, the machine may have alignment problems or side friction.If the surface coating falls off, the coating material may not match the product, temperature or cleaning method.You can send GOODLY photos of the broken belt and machine position. We can help check the possible reason and recommend a better belt structure.

In normal working conditions, a properly selected vulcanized timing belt can last longer than a weakly joined belt because the joint area is stronger and more stable. However, no belt has the same lifetime in every machine.Common reasons for short belt life include:Wrong belt sizeToo much or too little tensionPulley misalignmentSharp machine parts touching the beltOverload operationHigh temperature beyond material limitWrong surface coatingPoor installationTo extend belt life, we recommend checking pulley alignment, keeping proper tension and choosing the correct material for your working environment. GOODLY can also help analyze your old belt damage and suggest improvements.
