How is the black Angle of the bearing made
The bright side is a polished black side that is treated with a blackening (chemical treatment).
2. Definitions of bearing terms:
Bearing is an important part of modern machinery equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotary precision. Bearing can be divided into rolling bearing and sliding bearing according to the different frictional nature of moving element. Among them, rolling bearing has been standardized and serialized, but compared with sliding bearing, its radial dimension, vibration and noise are larger, and its price is higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and holding frame. According to the shape of rolling body, rolling bearing can be divided into ball bearing and roller bearing.
