Rely on the bearing inner ring shoulder and interference to achieve axial fixation. It applies to both ends of the fixed support structure. Needle roller bearing inner ring by the shaft shoulder and lock nut to achieve axial fixation. Friction surface temperatures on the rise, affecting the bearing sliding velocity V is much larger than the impact force P. Needle roller bearings, needle roller bearings NA4826, suffered load bearing size, direction and nature of the load is the most important factor in the choice of the bearing, so these two types of bearings when subjected to loads, needle roller bearings, the rolling element and raceway belong point contact needle roller bearings NKI140 / 32, less rigid. In addition, various types of bearings can also preload, to increase bearing rigidity purposes. Needle roller bearings NKI140 / 32 | governance and needle (Online) | needle roller bearings supplied by Linqing municipal and needle roller bearings plant.
