Types and Applications of Angular Contact Ball Bearings

What is Angular Contact Ball Bearing?
Angular contact ball bearings are the common type of ball bearings, they belong to ball bearings in rolling bearings, which can withstand radial and axial loads at the same time.
Angular contact ball bearings can work at relatively high speeds, and the larger the contact angle, the higher the axial load carrying capacity.
The contact angle of an angular contact ball bearing is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a 15°contact angle. Under the action of axial force, the contact angle will increase.
Types of Angular Contact Ball Bearing
There are three types of angular contact ball bearings: Single row angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.
Single row angular contact ball bearings have two structures: separable and nonseparable, because of more balls in bearings, high loading capacity and stiffness can be gained.Metal solid cages are mainly used in single-row angular contact ball bearings. Phenolic cloth laminated tube solid cages are usually used for high speed applications, and the maximum temperature of this bearing is 120℃.
Double row angular contact ball bearings correspond to a pair of single row angular contact ball bearings mounted back to back,but the width is narrower. Therefore, they are especially suitable for applications required high stiffness.Nylon or brass solid cages are generally used in double row angular contact ball bearings.
Four point contact ball bearings can carry axial loads in two directions and certain moment loads, and have the features of single row and double row angular contact ball bearings. They only can work normally in high speed when two point contact is formed. Brass or aluminium solid cages are exactly suitable for four point contact ball bearings.
Applications of Angular Contact Ball Bearing
Single row angular contact ball bearings are mainly used in machine tool spindles, high frequency motors, gas turbines, centrifugal separators, front wheel of small car, differential pinion shaft, etc.
Double row angular contact ball bearings are mainly used in oil pumps, roots blower, air compressor, fuel injection pump, printing machinery, and various of transmission, etc.
Four point contact ball bearings are mainly used in woodworking machinery, textile machinery drive shafts, vertical seat spherical bearings,etc.
