Life of rolling bearings of the number of revolutions (or in hours of work at a certain speed) Definition: In this life within the bearing roller bearings, initial fatigue damage should occur (peeled or chipped) on any of the bearing ring or rolling elements. However, both in laboratory tests or in actual use, self-aligning roller bearings price, can clearly see the self-aligning roller bearings sales agents, look at the same operating conditions of the same bearing, the actual life different. There are also several different definitions of the bearing "life", one of the so-called "working life", which represents the actual life of a bearing can be achieved before the damage is usually not damaged by the wear caused by fatigue, but It is caused by wear and tear, corrosion, seal damage and other reasons. FR .., FR..R and LR .. Spherical roller bearings picture, LR..R series installation guide roller adjustment and preload is .FR..Z and LR..Z carried out by its eccentric inner ring Series wheel is concentric design structure, eccentric wheel design in the inner side of the gap which is used to adjust the two blind holes, engages the rollers to the zero position, the rack and pinion with a gap of 0.05mm. is too large The preload may shorten the life of the entire system, while insufficient tightening, when the system is working, the wheel will not work, or because of poor meshing cause unexpected system wear.
