In modern industrial equipment, the bearing is an important component, its main role is to support the mechanical rotation mechanism, reduce its friction when moving, to ensure the accuracy of rotation, motorbike engine and transmission bearings, are used in high temperature, high speed, with impurities in the environment, so, must have the ability to resist impurities with rigidity, in addition, the bearing of the tyre, must be applicable to a variety of different terrain and As most of the mechanical parts are exposed to the elements, they have to withstand the rigours of high speed driving under adverse driving conditions. Therefore, in order to prolong the life of the motorbike, it is necessary to have better durability and sealing.

Motorbike rear wheel bearings, a large load, if long-term overweight, coupled with high salinity in precipitation ground driving, easy to lead to damage, affecting the service life, therefore, do not wait until the bearing is bad to go the outer edge to replace, it will be too late, to replace the rear wheel rim bearings, do not force to fight up, if it is summer, you can put the bearing in the refrigerator for a period of time, and then come to install will be better, the direction column left and right bearings, because the front Damping ineffective, wetting insufficient or left and right tightening strength discomfort, resulting in ball crushing or ball working surface of the off, produce orientation to turn for hair astringent or runaway, affect the driving safety, change the orientation bearing, must check whether the front damping is excellent, if bad, also to overhaul or replace, otherwise, the orientation bearing is also easy to bad.

Front and rear wheel rims after the chain plate on the bearing, because the owner in daily use, wading too deep or often wash the car, let the water into the bearing, so that the bearing in the grease slowly ineffective, produce bearing within the flip groove and ball wear serious, side gap significantly increased, if the factory or sales before and after the wheel installation is too tight or too loose, a long time led to driving instability, bearing stagnation or bearing offset loose, ball cage damage or fall off If the bearing on the rear chain turntable is too easy to get water or adjusted too tightly or too loosely, it will lead to destruction, so the owner should pay special attention when washing the car or when crossing a deep water hole, and check and maintain it in time.
