Axlebox with CRU DUPLEX
The bearing is made according to TU VNIPP.048-1-00. It is a double-row closed type bearing, adjusted according to clearance and bore dimensions of inner rings. The basic geometric parameters of the internal design completely conform to series-produced axle bearings with long-term experience of reliable operation on the railways of “1520 space”.
Upon that microgeometry of the bearing’s rollers and rings has special optimized profiles, with tightened requirements (letter "U") to mechanical surface treatment and special heat treatment of the material. The bearing is filled with lubricant Klüberplex BEM 41-132 HARP, specially developed in collaboration with Klüber Lubrication (Freudenberg Group) for the specific operating conditions of "1520 space".
