Custom Timing Belt Pulleys

Ondrives.US’ custom timing pulleys can reduce speed, increase speed, or transfer rotary motion from one axis/shaft to another. Our timing pulleys are fixed to the shaft via one or two set screws or with clamp-style hubs. When properly aligned, periodic belt tension adjustments are the only maintenance required to ensure maximum application performance.

Custom Timing Belts Manufactured to Your Application Requirements

A custom or modified standard timing pulley can be the perfect solution for your challenging motion transfer applications. Ondrives.US can design and manufacture a timing pulley that meets your application and performance requirements.
We can provide modified standard timing pulleys based on our MXL, XL, L, 40DP, T, HTD, or GT2 Series timing pulleys, or we can work with you to develop a custom timing pulley design that matches your unique specifications. Our custom pulley capabilities include:

Custom Timing Belt Pulley Design Options

Our modified standard and custom timing pulleys are available with no flanges, a single flange, or double flanges to hold the position of the timing belt. Generally, a pair of timing pulleys requires a minimum of two flanges (along with proper alignment) to ensure that the belt stays in position and does not run off the pulley. We can provide custom timing pulley flanges to guarantee a perfect fit and optimum performance.
Numerous features of Ondrives.US’ custom timing pulleys can be modified to provide the perfect solution for your motion transfer application. Options include:
  • Materials: plastics and most machinable metals
  • Material combinations: e.g., Acetal with a brass hub
  • Pulley size: up to 16” O.D.
  • Tooth count
  • Keyway(s) in bore
  • D-shaped or other specialty bore shapes
  • Set screws or clamp-style hubs
  • Multiple pulleys on a single part
  • Specialty plating or finish
  • and more
