Cam followers are specially designed needle bearings that are threaded for quick and easy attachment in cam and track roller applications.

Emerson Bearing offers two types of hex slot cam followers: the CR-B and CR-XB. Featuring anti-friction designs and organized in compact configurations, these cam followers provide excellent dynamic and static load carrying capabilities.

Cam followers are typically available in stud or yoke styles; stud styles have a pin for mounting while yoke styles feature a hole in the middle of the bearing. Our CR-B and CR-XB hex slot cam followers are constructed in stainless steel and designed in the stud style, ideal for moderate loads and shock levels.

CR-B cam followers are unsealed, with hex sizes ranging from 1/8” to ¾” and maximum static capacities running from 720 lbs. to 45,100 lbs. CR-XB products are sealed; they range from 1/8” to 1/8” in hex size and support 720 lbs. to 3100 lbs. in static capacity.
