Axially retain items on shafts with thinner than normal shaft collars. These custom clamping shaft collars are designed specifically for FRC applications where space on an axle is important.

Don't feel like dealing with spacers? Throw a shaft collar on there, and hold everything perfectly in place. We've got collars for every common FRC shaft size, including the 8mm CIM output shaft.

"Tired of hex broaching your own collars? We have collars for hex shaft, as well as standard round shaft."
