These crowned roller pulleys are designed to fit over 1.25" OD tubing. They are made from 70A durometer TPE and are great for keeping flat urethane belting centered on your tubes or for simply intaking game pieces using the rollers themselves.
Holes are included for 5/32 rivets that can be used for retention on tubes. Rivets nest nicely within the TPE material, leaving the rivet head slightly below the rest of the roller material.
