What's behind the needle roller bearing surface grease effect

One-way needle roller bearing during operation, it is necessary to be punctual to alter the appearance of it smooth oil, do the advantages of many, on the one hand can cut bearing internal conflict and wear, avoid burning stick, so alter the part of the smooth oil mainly constitute a bearing ring, touch each other part of the roll body and adhere to the device. On one-way needle roller bearing, its fatigue life spans are associated with smoothness, if in the process of bearing rotating rolling contact surface smooth and good, has extended its fatigue life spans. On the contrary, low oil viscosity, smooth and oil film thickness owe good, shorten the exhaustion of needle bearing life. , on the other hand, punctuality is a one-way needle bearing can alter smooth oil discharge by the heat of conflict attack, or coming from external heat, cooling effect, avoid overheating bearing as well as the aging of smooth, and so on, for extending parts using full play an active effect. In addition, one-way needle bearing appearance altered smooth oil also has to avoid foreign body into bearing internal, or avoid the effect of rust and corrosion. Punctual in addition to alter smooth oil, but also to grasp the correct way to smooth, in order to make the bearing function well, first, to choose appropriate use condition, the purpose of smooth solution. If only think in terms of smooth, oil slick predominate smoothness, But can simplify the one fat smooth around the bearing structure of expertise, so you need to compare fat and oil slick smooth interest, and in combination with the practice of one-way needle bearing operating condition.
