Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
Sliding bearings have neither inner and outer rings nor rolling elements, and are generally made of wear-resistant materials. Commonly used in low speed, light load and mechanical rotating parts that are difficult to lubricate and maintain.
spherical plain bearing
The sliding contact surface of the spherical plain bearing is spherical, which is mainly suitable for swing motion, tilt motion and rotary motion.
Rolling bearings are divided into radial bearings and thrust bearings according to the load direction or nominal contact angle they can bear. The radial contact bearing is a radial bearing with a nominal contact angle of 0, and the radial angular contact bearing is a radial bearing with a nominal contact angle greater than 0 to 45. Axial contact bearings are thrust bearings with a nominal contact angle of 90, and thrust angular contact bearings are thrust bearings with a nominal contact angle greater than 45 but less than 90.
