Bearing is an important component in mechanical equipment, whose main function is to support the rotating body of the machine, reduce the friction coefficient during its motion, and ensure its rotational accuracy.
Bearings can be divided into two categories: rolling bearings and sliding bearings.
The daily maintenance and upkeep of bearings include lubrication, cleaning, installation and disassembly, operation monitoring, storage, and protection. The causes of bearing wear include peeling, burns, crack defects, and damage to the retaining frame. The treatment methods include checking the machining accuracy of the shaft and bearing housing, checking the type of lubricant to ensure injection volume, setting appropriate interference fit, and inspecting the material.

bearing material
Characteristics of bearing steel:
1, Contact fatigue strength
Under the action of cyclic loads, bearings are prone to fatigue damage on the contact surface, such as cracking and peeling, which is an important form of bearing failure. Therefore, in order to improve the service life of bearings, bearing steel must have high contact fatigue strength.
2, Wear resistance performance
During the bearing task, not only rolling friction but also sliding friction occurs between the ring, rolling elements, and support frame, resulting in continuous wear of the bearing components. In order to increase the wear of bearing components, maintain the stability of bearing accuracy, and extend the service life, bearing steel should have good wear resistance.
3, Hardness
Hardness is one of the important qualities of bearing quality, which indirectly affects contact fatigue strength, wear resistance, and elastic limit. The hardness of bearing steel under certain operating conditions should reach HRC61~65, which enables the bearing to achieve high contact fatigue strength and wear resistance.
