What is the most common type of ball bearing?

The most common types of ball bearings include deep groove ball bearings, angular contact ball bearings, and self-aligning ball bearings.

Ball bearings are divided into deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, four-point contact ball bearings, thin-walled bearings and mini bearings and other seven types.
First. Deep groove ball bearings
Deep groove ball bearings are one of the most commonly used types of ball bearings and have the advantages of simple structure, large load capacity and long service life. They are mainly used in low speed and high load fields, such as power tools.

Second, angular contact ball bearings
Angular contact ball bearings bear radial and axial loads, can keep the load stable at the same time, has a long life and smooth operation and other characteristics. Mainly used in high-speed areas, such as spindles, motors and so on.

Self-aligning ball bearings
Self-aligning ball bearings can still work under the situation of mounting deviation and rotational deviation, and have the advantages of automatic centering and large load carrying capacity. Mainly used in heavy load, vibration and high speed field, such as vibrating screen, road roller and so on.

Fourth, thrust ball bearing
Thrust ball bearings can bear large axial load in one direction, compact structure and easy to install. Mainly used in large-scale heavy equipment, such as cranes, hydraulic presses and so on.

Five, four-point contact ball bearings
Four-point contact ball bearings bear radial and axial load, can keep the load stable, and in the bearing has high flexibility and adaptability. Mainly used in joints, rotary table and other rotating equipment.

Six, thin-walled bearings
Thin-walled bearings have a compact structure, light weight, high stiffness, and are indispensable parts in various light mechanical equipment. Widely used in chucks, robots, medical equipment and so on.

Seven, mini bearing
Mini bearings are small bearings with a diameter of less than 9 millimeters, with a simple structure and a wide range of applications, they are widely used in electric toys, wireless electronic equipment, hand-held tools and other fields.

Ball bearings are divided into seven types: deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, four-point contact ball bearings, thin-walled bearings and mini bearings. Different types of bearings have different structures and areas of application to meet various usage requirements.
