- Volume Discount
IKO Cam Followers are bearings with a stud incorporating needle rollers in a thick walled outer ring.These bearings are designed for outer ring rotation,and have superior rotational performance with asmall coefficient of friction.Also, they are designed to have minimal radial internal clearance to increase the loading zone, and thusreduce the effect of shock loads and ensure stablelong life.
·As studs already have threads or steps, they are easy to mount.
·With Cage
·Sealed Type
·With Screwdriver Slot
