Axially retain items on shafts with thinner than normal shaft collars. These custom clamping shaft collars are designed specifically for FIRST ® Robotics Competition 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 FIRST ® Robotics Competition shaft size, including the 8mm CIM output shaft.
