Timing Belt Pulleys for Small Power Transmission Applications
We supply hobbyists, students, distributors and a wide variety of OEMs with high-quality machined timing belt pulleys and molded pulleys at affordable prices.
SDP/SI offers a broad range of off-the-shelf inch and metric timing belt pulleys. Aluminum, steel or plastic pulleys are available with or without metal inserts, metal hubs, set screws or Fairloc® hubs.
As a complete source for small power transmission components, our pulleys are offered in the same profiles as our timing belt selection: 40 D.P., miniature FHT® 1, 2, & 3 mm, Gates PowerGrip GT®2, Gates PowerGrip GT®3, Gates HTD, L, MXL, T, and XL.
For over 50 years we have helped design engineers build synchronous drive systems. Our engineers can assist in the selection of a standard catalog item to meet your need. Sometimes, there are applications where the standard catalog item doesn't meet all requirements. Modifications, custom components or custom drive systems can be designed, engineered, manufactured and assembled in-house.
Design Your Belt and Pulley Drive SystemDesign your belt drive system using our Center Distance Designer. This calculator computes belt lengths for various center distances and checks the number of teeth in mesh for both pulleys. It calculates pulley drive ratios and the minimal center distance for a designated pulley pair.
The Center Distance Designer shows all available pulleys and belts that fit within your criteria. Click on the part number for instant access to product specifications, 3D CAD Models, pricing and availability. Belts and pulleys ship within 24 hours from stock. If a standard catalog item doesn't meet your needs we can provide custom alternatives, call 516-328-3300 for engineering assistance.
