Idler Pulleys

Idler pulleys are designed to guide belts or cables and to provide tension in vehicles such as automobiles and lawnmowers.  Our customers have been satisfied with the quality and durability of our pulleys for decades.  At Capitol Stampings we produce both steel and composite idler pulleys.  Each of them has the same commitment to quality, but each has its own strengths and weaknesses.  If you aren’t sure which one is best for your application, one of our engineers will be able to help you decide.

Proud to be an American manufacturer!

We do not source steel or manufacture pulleys from any overseas markets or in Mexico. We build all of our pulleys, sheaves, and spindles in the U.S.A.!  We don’t compromise on quality from the sourcing of our materials to the parts we produce.  You can count on us, no matter what the size of your order!
