The linear motion assembly is a type of rolling bearing used to support and guide a translating member along a round shaftway. The load-carrying adequacy of this bearing for a given application is evaluated in the same way as for conventional rolling bearings by determining a statistical fatigue life. This paper presents an analytical development of the equations for dynamic capacity from which fatigue life can be calculated. Contact deflection and the effects of preload are also examined.
