Polyurethane Pulley

This pulley is designed to work on a 1/2 hex shaft and run a 1/4 diameter polyurethane timing belt. I designed this pulley for FRC 2017 SteamWorks to pick up 5" wiffle balls on our robot. It is intended so that the 1/4 belt stays in contact with the ball even when the ball goes over the pulley. The hex hole is .515 inches so that a hex shaft fits snug but without needing lot of force to slide into a desired position. The text was added in team spirit but please feel free to remove it if you
