Description:

Cam followers have an internal design very similar to that of a needle or cylindrical roller bearing. They are characterized by a thick-walled outer ring that enables them to accommodate shock loads while reducing distortion and bending stresses. The outer ring running surface is crowned as standard. However, cam followers with cylindrical (flat) running surfaces are available for certain applications.

Instead of an inner ring, cam followers have a solid stud (pin) that is threaded so that the cam follower can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.

Axial guidance for the outer ring is provided by an integral flange at the head of the stud and a flange ring pressed onto the stud, or by the roller complement. Cam followers are pre-greased, ready-to-mount units that are suitable for all types of cam drives, tracks and conveyor systems.

cam followers are available in three basic designs:

KR design
NUKR design
PWKR design

All three cam follower designs have the same main dimensions. The differences are in their internal design, which make them suitable for various operating conditions. In contrast to ball and roller bearings, where the bearing size refers to the bore diameter d, for cam followers the size refers to their outside diameter D.

All designs are available with a concentric seat (fig 1) or an eccentric collar (fig 2) on the stud. An eccentric collar, which has a shrink-fit onto the stud, enables less stringent manufacturing position tolerances to be specified for associated components. The values for the adjustable eccentricity are listed in the product tables. An eccentric collar is identified by the letter E at the end of the basic designation.
