Information

Roller bearing is a kind of rolling bearing, and it is one of the parts widely used in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection.

Rolling bearings are divided into ball bearings and roller bearings according to the rolling force.

Roller bearings rely on the rolling contact between the main parts to support the rotating parts. Different roller bearings can withstand different radial and axial forces. When choosing roller bearings, the choice should be made according to specific working conditions.

Roller bearings mainly include spherical roller bearings, thrust spherical roller bearings, tapered roller and cylindrical roller bearings, etc.

Advantages and types of insulated bearings

Good insulation performance, using a special sealing method, J20AA coating can effectively insulate even in a humid environment, insulated bearings can be interchanged with standard bearings. For special occasions, such as outer ring rotation, bearings with J20C coating on the inner ring are recommended.

Analyze the different types of bearings and their uses

Rolling bearings are classified into radial bearings and thrust bearings according to the load direction they bear or the nominal contact angle. Radial contact bearings are radial bearings with a nominal contact angle of 0, and radial contact bearings are radial bearings with a nominal contact angle greater than 0 to 45. Bearings are an important part of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearing models generally consist of pre-code, basic code and post-code.

Bearing Knowledge" What is an axle box device? How to maintain it?

The axle box temperature is related to many factors, such as the load on the FAG bearing, operating speed, line status, air temperature, wind speed, continuous running time, quantity and status of lubricating grease, etc., all have a significant impact on the axle temperature. Two to three hours after the start of the vehicle, the bearing temperature tends to stabilize, and the heat generated by the friction of the bearing and the heat radiated from the outer surface of the axle box are close to balance. In the cold northern areas, the surface of the axle box dissipates heat quickly. The temperature difference between the top of the axle box and the inside of the bearing is as much as 30 to 40 degrees, while in the southern hot season, the temperature difference between the top of the axle box and the inside of the bearing is only about 100 degrees. Usually in summer, the temperature of the axle box on the side of the sun is much higher than the side of the back sun.
