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.

Heavy Stud types are preferred for high-loads and/or heavy shock applications. Available in stainless steel and with seals.
