C.R. radial ball bearings are mainly used for fork lift masts.
They are manufactured in rigid execution, with two or four contact points and with one or two crowns of balls which are separated by a polyamide cage.
This series of bearings presents a quite good radial load capacity and a very good resistance against the axial thrusts.
Ball bearings with cage for fork lift masts have the following features:
The outer ring is made of UNI 20 CrMnTi cementation steel, with surface hardness
degree 60-
The inner ring is made of total hardened UNI 100Cr6 steel, with surface hardness degree 60±2 HRC.
These bearings are designed with a limited radial clearance and with small size sections.
