Briefly explain the calculation of bearing life
The Calculation of Bearing Life
In order to accurately calculate the life span of bearing, one must first understand what a bearing is and what forces can cause it to wear out prematurely. A bearing is a device which supports and locates a rotating shaft in a predetermined position in relation t......
