Cam followers with cylindrical rolls, cage and eccentric bush - NUKRE Series
The rollers of this type of bearing have a very thick outer ring in order to guarantee the mechanical strength to reduce deformations due to loads and to bear high impacts.
The ring is cambered in order to prevent possible concentration of loads on the side bands of the bearing ring, to reduce the contact pressure, so less wear and longer life of the runway.
This type of product is a unique group and, being equipped with a pivot with threaded shank, it is very easy to install.
As far as lubrication is concerned, there are some holes on the side surface, and on both ends of the pivot.
As these rollers slide on flat bearing rings, it can occur an elastic deformation of their outer ring, so it is recommended to refer to loads as rollers (Cw and C0w).
