Custom Timing Pulleys

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 completely custom timing pulley design that matches your unique specifications.

High Performance Timing Pulleys

Ondrives.US’ custom timing pulleys can be used to reduce speed, increase speed, or transfer rotary motion from one axis/shaft to another. When properly aligned, the only maintenance required for optimum performance is periodic belt tension adjustment. If not properly tensioned, the timing belt may jump or skip the timing pulley groove and cause the assembly to lose indexing; this can also be caused by angular misalignment or torque overload. Our timing pulleys are fixed to the shaft via one or two set screws or with clamp-style hubs.

Timing Belts & Timing Pulley Flanges

Due to differences in pitch, size, and tooth shape, different profiles are not interchangeable. Therefore, timing pulleys and timing belts must have matching profiles. If you’re using a modified standard timing pulley, we can pair it with one of our MXL, XL, L, 40DP, T, HTD, or GT2 timing belts.
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. In general, 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.

Custom Timing Pulley Options

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
