What are the classification of bearings? How many have you seen?

When it comes to "bearings", you will not be unfamiliar with them. There are bearings in almost rotating places, such as fans, motors, transport vehicles, etc. What are the classification of bearings? The following small series for you to introduce some bearings, hoping to help you better understand and apply bearings!

Common bearings are divided into sliding bearing, spherical plain bearing and rolling bearing according to the friction mode.

The sliding bearing is made of wear-resistant material without inner and outer rings or rolling elements. It is commonly used in low speed, light load, lubricating oil filling and difficult maintenance of mechanical rotating parts.

The sliding contact surface of spherical plain bearing is spherical, which is mainly suitable for swing motion, tilt motion and rotation motion.

Rolling bearing is generally composed of inner ring, outer ring, rolling element and cage. The function of the inner ring is to match with the shaft and rotate with the shaft; the function of the outer ring is to match with the bearing seat and play a supporting role;
