Cam follower bearings, which follow tracks or cams in linear motion systems, are essential for conveyors and other applications in packaging, automotive, food processing, metal processing, and many other industries.
For applications requiring higher levels of precision, Emerson Bearing offers CR-XBEC eccentric stud hex slot cam followers in multiple configurations. The eccentric stud design of these needle bearings allows for seamless mounting and alignment.
Constructed from stainless steel, the CR-XBEC line features a heavy outer ring designed to accommodate different needle rollers and a crowned style to reduce or eliminate pre-loading, clearance, and wear compensation problems.
CR-XBEC cam followers are sealed. Their dimensions range from 0.500” roller OD by 5/8” stud length to 2.750” by 2-1/4”. Available configurations also include crown radii from 7” to 30”, hex sizes from 1/8” to ½”, and basic dynamic ratings from 970 lbs. to 15,280 lbs. Emerson’s stud cam followers work best in settings with moderate loads and shocks.

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. Eccentric studs allow for a more precise mounting and alignment. They eliminate problems of clearances, preloading and wear compensation.Available in stainless steel and with seals.
