Development of Thrust Carrying Cylindrical Radial Roller Bearings

The axial load carrying capacity of cylindrical roller bearings is not primarily related to the fatigue strength of the material, but to the lubrication conditions, and consequently the contact conditions between the roller ends and the guiding surface of the flange. Therefore, friction and attendant heat generation should be as low as possible at these contact positions. Analysis and testing have enabled the optimum geometric form for the roller end/flange contact to be defined with respect to minimum friction.
