CF8 / KR19 Needle Roller Bearing Bolt

A Needle Bearing, also known as a cam follower, is a compact bearing featuring a high-strength shaft and an internal needle bearing. It is ideal for use as a roller rail in cam mechanisms and linear motion systems of automated and specialized machinery.

The CF8 Bearing model is an affordable option with a hex socket or driver slot on the rod end. This model is made entirely of stainless steel (marked M).

The KR19 Bearing Housing supports the assembly as a reliable Screw-Mounted Bearing.
