In general, if rolling bearings are used correctly they will survive to their predicted fatigue life. It also reduces energy consumption as sliding motion is replaced with low-friction rolling. By accepting, you agree to the updated privacy policy. In contrast to fatigue life, this premature failure is caused by improper mounting, handling, or lubrication, entry of foreign matter, or abnormal heat generation. Gears with similar tooth profiles mesh. function of a bearing. Bearing life can be affected based on the type of bearing, the load they are asked to carry and the maintenance schedule. While the initial costs are higher, the longer lifespan in tough conditions makes up for it in the longer run. Looks like youve clipped this slide to already.
