One-way needle bearing surface the effect after the grease

One-way needle roller bearing during operation, must be regularly to the surface of the grease, do have a lot of the benefits of, on the one hand can reduce the bearing internal friction and wear, prevent burning stick, in this case, the site of the grease is mainly constitute a bearing ring, rolling body and touch each other part of the retainer. For one-way needle roller bearing, its fatigue life is associated with lubricity, if in the process of bearing rotating good lubrication performance of the rolling contact surface, prolong the fatigue life. On the contrary, the oil viscosity is low, the thickness of lube film is not good, will shorten the fatigue life of needle bearing. Timing for one-way needle roller bearing, on the other hand, the grease can discharge by friction heat, or by an external sound of hot, have the effect of cooling, prevent overheating bearing and lubricating oil's own aging, etc. , to extend the service life of parts has played a positive role. In addition, one-way needle bearing surface grease inside also has to prevent foreign matter into the bearing, or to prevent rust and corrosion effect. In addition to regular the grease, but also to master the correct lubrication method, in order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If just think in terms of lubrication, oil lubricity dominant; Grease lubrication, however, can simplify the structure of bearing the surrounding of the special features, so you need to compare the pros and cons of grease lubrication and oil lubrication, and connecting with the actual operation condition of one-way needle roller bearing.
