Emerson Bearing - YR, YR-X 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.

Yoke type rollers are used for heavier loads and where clevis or shaft mounting is preferred. Available in stainless steel and with seals.
