Single Row Angular Contact Ball Bearing
Single row angular contact ball bearings can only withstand axial loads in one direction. When such bearings are subjected to pure radial load, they must be installed in pairs because the line of action of the rolling body load and the line of action of the radial load are not in the same radial plane, resulting in an internal axial component force.

(1) Separated angular contact ball bearings
The bearing, code-named S70000, has no lock on the edge of the outer ring raceway and can be separated from the inner ring and cage rail ball assembly, so it can be installed separately. These are mostly micro bearings with an inner diameter of less than 10mm, which are used in devices with high requirements for dynamic balance, noise, vibration and stability such as gyro rotors and micro motors.
(2) non-separated angular contact ball bearings
The ring channel of this kind of bearing has a lock, so the two rings can not be separated. Divided into three types according to the contact Angle:
① Contact Angle α=40°, suitable for bearing large axial loads
② Contact Angle α=25°, mostly used for precision spindle bearings;
③ Contact Angle α=15°, mostly used for large size precision bearings.
(3) Angular contact ball bearings configured in pairs
Paired angular contact ball bearings are used to withstand both radial and axial loads, and can also withstand pure radial loads and axial loads in either direction. This kind of bearing is selected and combined by the manufacturer according to certain pre-load requirements and provided to the user. When the bearing is installed on the machine, the clearance in the bearing is completely eliminated, and the ring and the ball are in a pre-tight state, thus improving the rigidity of the combined bearing.
1. High-speed operation, very accurate (can control the rotor position).
2. Can withstand huge pure axial load or radial axial combined load The most important feature is that the bearing will bear huge axial load and high-speed operation of the dual capacity in one. In the case of small clearance or light preload, the single row angular contact bearing enables the precise positioning of the rotating shaft.
3. The raceway of this type of bearing is designed to form a certain Angle (contact Angle) with the axis of the bearing, so that it can bear a much greater axial load than the deep groove ball bearing.
SKF,FAG,NSK,KBC,NTN and other brands of bearings and special bearings customized according to customers’ needs have been produced, boxed in our warehouse and waiting to be packed and delivered to you. Please send us the types of cylindrical roller bearing you need, we will give you the best cylindrical roller bearing price
Compared with single row angular contact ball bearings, double row angular contact ball bearings have better rigidity and can withstand overturning moment. Bearings are non-separated. Especially suitable for applications with high rigidity requirements. It is widely used in the front wheel hub of the car (some models also use double row tapered roller bearings of the same size).
