Item # CR-3 1/4-C, CR-C, CR-XC Crowned Screwdriver Slot On Emerson Bearing

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. The crowned style cam follower is used where the track may not be exactly aligned and square with the cam follower. Available in stainless steel and with seals.
