Product Description
1.KR design cam followers are fitted with a needle roller and cage assembly. They are also available with a full complement needle roller set, which is identified by the letter V at the end of the basic designation. The outer ring is axially guided by the pressed-on flange ring and the head of the stud, which also serves as an integral flange.

3. KR design cam followers are also available with an axial sliding ring made of PA66 on both sides, identified by the designation suffix PPA , PPSKA or PPXA. In the radial direction, the sliding ring forms a narrow labyrinth seal with the outer ring to protect against coarse contaminants. In the axial direction, the sliding ring serves as a contact seal to reliably retain grease in the bearing. This improves the lubrication conditions in the bearing, keeps friction and frictional heat low, and extends grease life.
