The cam followers incorporate a polymer layer that is molded directly onto the IKO exclusive thin-walled steel outer ring. This construction solves the dilemma of being able to install a cam follower with special polymers, offering self-lubricating and shock-absorbing properties into existing applications. 
In heavy-duty cam-driven machines, improper mounting often causes misalignment that produces thrust forces and metal contact between the bearing’s outer ring and side plate. Heavy loading also creates deflections and uneven loading at the stud. Heat resulting from metal-to-metal contact can further reduce the cam follower’s life.
