CR-B, CR-XB Hex Slot
Cam Followers / Yoke Rollers
Cam Followers are anti-friction needle bearings developed for use in cam or track roller applications. They consist of a heavy outer ring cross section with a full complement of needle rollers. They offer high dynamic and static load carrying capability in a compact design. Cam Followers are offered in many design alternatives.
Standard stud cam followers are recommended where loads and shock are moderate. Available in stainless steel and with seals. less
Cam followers are specially designed needle bearings that are threaded for quick and easy attachment in cam and track roller applications.
