Bearings are widely used in a variety of machinery, it can be said that as long as it is a running machine, it can not be separated from bearings, bearings are the key components of motorcycles.
Because most of the mechanical parts of the motorcycle are exposed, it is subjected to the severe test of high-speed rotation in the harsh driving environment, which requires that the motorcycle bearing needs to meet the good durability and high sealing to extend the service life of the motorcycle.
Motorcycles vary according to the model and construction, but each motorcycle is generally equipped with 20 to 30 bearings. These bearings are used for the important rotating parts of the engine, variable speed device, wheel and so on, which are responsible for reducing friction and promoting the power of the engine to be effectively transmitted to the wheel.
The performance required for motorcycle bearings
(1) Smooth rotation through low friction and low vibration;
(2) with foreign body resistance and high rigidity;
(3) Durability must be ensured;
Bearings for motorcycle engines and variable speed devices are required to be used under the conditions of high temperature, high speed rotation and great impact load in a foreign body environment, so they are required to have foreign body resistance and high rigidity. In addition, wheel bearings must be suitable for use in various terrains and purposes, so they must also be durable to water and mud.
On motorcycles, ball bearings are generally used in the engine internal drive train and wheels, flat ball bearings are used on the front fork, and needle roller bearings are used on the crankshaft connecting rod and part of the transmission gear shaft.
Generally speaking, the front wheel of the car below 100cc is 6200, 6201, 6300, 6301 rear wheel is 6301;
125cc and 150cc cars have front wheels 6301 and rear wheels 6202, 6302, 6200, 6201, 6202, 6203, 6204, 6205, 6206, 6300, 6301, 6302, 6000, 6001, 6002, 6003, 6004, 62/22, 62/28 62/32, 63/22, 63/28, and 63/32 are also commonly used.
