The internal clearance of the bearing is the total distance that one of the bearing rings can move in a radial (radial clearance) or axial (axial clearance) relative to the other bearing ring. The clearance of the bearing before installation is the initial clearance.

Hub bearings are important moving parts for automobiles. The hub axle bears the burden of reducing the frictional resistance during the operation of the chassis and maintaining the normal driving of the car. If the hub bearing is faulty, it may cause noise, bearing heat, etc., especially the front wheel is more obvious, which may lead to dangerous phenomena such as out of control. Therefore, the hub bearings must be maintained on schedule.

Bearing steel is steel used to make balls, rollers and bearing rings. Bearings are subjected to extreme pressure and friction during operation, so bearing steels are required to have high and uniform hardness and wear resistance, as well as high elastic limits.

With the development of today's society, the application fields of ceramic bearings are becoming more and more extensive, which has made tremendous contributions to the development of people's life and technology. So do you understand the advantages of ceramic bearings and its own characteristics? The following will take you to the inner world of the ceramic bearings!

Tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load carrying capacity. This type of bearing is a split type bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing.

Rolling bearings are made of bearing steel and heat treated, so rolling bearings not only have high mechanical properties and long service life, but also save the expensive non-ferrous metals used in the manufacture of sliding bearings. Since the rolling bearing has high transmission efficiency and low heat generation, the consumption of lubricating oil can be reduced, and lubrication maintenance is relatively trouble-free.
