Custom timing belt pulley manufacturing
Commercial Gear & Sprocket manufactures custom timing belt pulleys and gear belt pulleys for OEMs, machine builders, replacement applications and industrial equipment — in multiple tooth profiles, custom belt widths and customer-specific configurations.
Timing pulleys made to your specifications
Timing and gear belt pulleys use a defined tooth profile that engages a matching toothed belt. Profile, pitch, width, bore and every other dimension must suit the belt and the machine.
We manufacture custom timing pulleys to your drawings, dimensions, tooth profile, pitch, belt width, bore configuration, material and quantity — trapezoidal, metric curvilinear, Gates PowerGrip®, Goodyear Super Torque Pd®, metric T and AT, 40 DP and zero-backlash pulleys, all in custom belt widths.

Manufacturing
To your requirements
Bore size, hubs, keyways, mounting holes, material, tolerances, finishing and inspection should be shown on your drawing or reviewed during quotation.
How we manufacture custom timing pulleys
Custom pulley manufacturing with CNC machining, secondary operations and customer-specific finishing — the approach depends on tooth form, pitch, diameter, face width, bore, material and quantity.
Trapezoidal, HTD®, PowerGrip®, Super Torque Pd®, metric T and AT, 40 DP and zero-backlash — specify the pulley around your belt system.
Every listed profile can be made in any custom belt width — ideal for replacements and non-standard drives.
CNC lathes with live tooling and sub-spindles plus a 4-axis CNC vertical mill for bores, hubs, keyways and holes.
Deburring, finishing, heat treatment and metal finishing through outside sources, and inspection.
Custom belt widths
Because our pulley profiles can be made in any custom belt width, we can match an existing belt-drive system, OEM machine or specialized equipment rather than forcing a standard width. Supply the exact width and mating belt with your drawing.
Any width for listed profiles
Available on request
Bores, hubs, keyways, holes
Timing pulley tooth profiles
A timing pulley has to match its belt exactly. We support a wide range of tooth forms so you can specify the pulley around your belt system instead of redesigning the drive.
Available tooth forms:
MXL (.080″), XL (.200″), L (.375″), H (.500″).
HTD® 3M, 5M, 8M · Gates PowerGrip® GT 2, 3, 5, 8MM.
Goodyear STPD 3M, 5M, 8M · metric T2, T2.5, T5, T10, T20.
AT5, AT10, AT20 · 40 DP (.0816″) · zero backlash.
