Resistance of the Roller Cage in Cylindrical Roller Bearings for Rail Car Axle Boxes.

The behavior of cylindrical roller bearings for railway axle-boxes has already been a subject of a considerable amount of literature. However, following a series of operating inconveniences and consequent studies and research, it has been show that the roller cage is an element of primary importance for the life of the bearing and safety of operation. Details of extensive research and theoretical studies are presented and tests confirming these findings are described. They provide a clearer understanding of the behavior of the cage in the course of operation. The main cause of cage failure is the loosening of the riveted joints leading to the rupture of rivets and the breakdown of axle boxes.
