NSK Angular contact ball bearings 7244
Generally speaking, single-row angular contact ball bearings not be used alone, because this type of bearings will have axial component force when bearing radial load. For this reason, double angular contact ball bearings should be used face to face or back to back. To angular contact ball bearings, the standard contact angles are 15 degree, 25 degree, and 40 degree and exists between balls and rings. The axial load capacity determined by contact angle, the bigger contact angle, and the bigger axial load capacity. The bigger the contact angle is, the bigger advantageous to rotation it will be. Single row angular contact ball bearings can accommodate radial load and axial load from one direction. NSK bearing company provide the angular contact ball bearings at single row and double row angular contact ball bearings.
Two single row angular contact bearings combined back to back in structure have common inner and outer rings, capable of bearing axial load and bi-directional axial load. Augular contact ball bearings are very suitable for a high speed and accuracy occasions. For example: NSK angular contact ball bearings 7244
