Introduction to bearings for motorcycles and automobiles

Bearings are widely used in motorcycles and cars. The main function of automotive bearings is to ensure durability and contribute to smooth driving. These bearings support the main functions of motorcycles by reducing friction, running smoothly and ensuring that the engine's power is continuously transmitted to the wheels. The movement of rotating parts such as wheels, engines and gearboxes.

Bearings for motorcycle engines and transmissions must have extremely high stiffness and excellent dust-proof performance. They must cope with the intrusion of external pollutants (such as water, oil, particulate matter, etc.) at high speeds, and withstand impact loads at high temperatures. Due to the wheel Bearings are often subject to various road conditions, so the durability of bearings in mud and water is also important.


On average, there are about 100 to 150 bearings in a vehicle with a conventional engine. Depending on the model and its structural elements, there are 20 to 30 bearings built into a single motorcycle, mainly concentrated in a few car parts. One is the wheel. , wheels are usually equipped with ball bearings to support fast movement requirements, and the bearings are installed in cages to help the wheels work properly.


The second is the engine. During the operation of the automobile piston engine, the crankshaft and other rotating engine parts are supported by various bearings. In this case, different types of bearings are used, including ball bearings, tapered roller bearings and thrust ball bearings.


The third is the transmission. The transmission is the most important part of the car. It converts engine energy into kinetic energy through gears. In these cases, the shaft is supported by bearings so that the required force can be applied to control the speed. According to the axial and Radial loads, such applications may use deep groove ball bearings, cylindrical roller bearings and tapered roller bearings.
