High Freight & Minimums
European mxl timing belt pulley MOQ of 500โฏpcs ties up capital. We offer MOQ 10โฏpcs and consolidated airโsea freight saving โค32%.
Complex sourcing & long lead times
Coordinating GT2, GT3 and MXL from different vendors doubles inspection cost. Oneโstop supply + 12โday lead time cuts procurement cycle by 41%.
๐ 73% of buyers report that pulley quality directly impacts their machine warranty cost. (Internal survey 2025, n=420)
โ๏ธ PrecisionโEngineered GT2, GT3 & MXL Timing Belt Pulleys
Our gt2 timing belt pulley range (2โฏmm pitch) delivers ยฑ0.02โฏmm positional repeatability for highโspeed pickโandโplace. The gt3 timing belt pulley (3โฏmm pitch) is optimised for torque transmission up to 18โฏNยทm. The classic mxl timing belt pulley (0.080โณ pitch) remains the standard for legacy medical and printing equipment.

โญ Real Praise from Global Engineers & Buyers

Procurement Manager, DE
โWe replaced our previous GT2 pulleys with Oriental Industryโs. Runout dropped from 0.10โฏmm to 0.02โฏmm โ our printer calibration time halved.โ

R&D Engineer, UK
โThe GT3 pulley with 40Cr + quenching is a beast. We run 16โฏh/day, 6โฏdays/week โ after 14โฏmonths no measurable wear. Highly recommend.โ

Operations Director, US
โMXL pulleys for our legacy film processors โ exact fit, no modification needed. 40% cheaper than original OEM and lead time was 11 days.โ

Supply Chain Manager, SE
โConsolidating GT2, GT3 and MXL from one supplier saved us 27% on logistics. The quality documents are always complete โ ISO, RoHS, batch trace.โ
โ Frequently Asked Questions
๐น What is the difference between GT2 and GT3 timing belt pulleys?
GT2 (2โฏmm pitch) is optimised for lightโduty, highโspeed positioning like 3D printers and laser engravers. GT3 (3โฏmm pitch) offers higher torque capacity (โค18โฏNยทm) and hardened steel for industrial CNC and medical robots. GT3 pulleys typically have wider face width and heavier crossโsection.
๐น Can I use an MXL pulley with a GT2 belt?
No. MXL uses a trapezoidal tooth profile (0.080โณ pitch) while GT2 uses a curvilinear profile (2โฏmm pitch). They are not interchangeable. Using mismatched pulley/belt will cause skipping and rapid wear.
๐น What materials do you offer for GT2/GT3/MXL pulleys?
Standard options: 6061โT6 aluminium (light duty), 45โฏ# steel (general purpose), 40Cr alloy steel + quenching (heavy duty, HRC 48โ52), and SUS304 stainless (food/medical). Brass also available for MXL.
๐น What is the minimum order quantity (MOQ) for custom bores?
For standard bores MOQ = 10 pcs. For custom bore + keyway, MOQ is 50โฏpcs. We also offer sample service (1โ5 pcs) with full inspection report.
๐น How do you ship and what are typical lead times?
๐ฆ Express (DHL/FedEx): 5โ7 days ยท Air freight: 8โ12 days ยท Sea freight: 25โ35 days. Lead time for stock pulleys: 3โ5 days; for custom: 12โ18 days. We consolidate orders to reduce your freight cost.
๐น Do you provide technical drawing support for OEM designs?
Yes. Our inโhouse engineering team (12โฏsenior engineers) can design custom gt2 timing belt pulley, gt3 timing belt pulley, and mxl timing belt pulley based on your shaft dimensions, torque requirements, and space constraints. Free DFM feedback within 48โฏh.
๐น What certifications do your pulleys carry?
All standard pulleys comply with ISOโฏ9001:2015, CE, RoHS, and REACH. Upon request we provide material certificates (ENโฏ10204 3.1), CMM inspection report, and batch traceability.
