Inch Mechanical Drive Components We know that sometimes it takes a custom timing belt and pulley drive system to make everything run smoothly. SDP/SI can modify any of our existing stock timing pulleys and cut custom timing belt widths for your unique application, creating a custom solution! SDP/SI offers fast-turnaround on precision-engineered components, secondary operations, off-the-shelf or custom components, materials, and specifications.

Many styles, sizes, and configurations are available.

Q: Do you need to open up a bore?
Q: Would you have better results with a lighter plastic pulley?
Q: Do you need a keyway?

A: Whatever your requirements are, we can create a custom pulley specifically for your needs. All of our quality custom-manufactured components are built to deliver the most consistent performance.
