Description

Angular contact bearing

Technical Field

Background

The angular contact ball bearing mainly bears larger unidirectional axial load, and the larger the contact angle is, the larger the load bearing capacity is. The material of the retainer is steel plate, brass or engineering plastic, the forming mode is stamping or turning, and the material is selected according to different bearing forms or using conditions. Other types include combined angular contact ball bearings, double-row angular contact ball bearings and four-point contact ball bearings. Angular contact ball bearings can simultaneously withstand both radial and axial loads. Can work at higher rotating speed. The larger the contact angle, the higher the axial load capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under axial force, the contact angle increases. The single-row angular contact ball bearing can only bear axial load in one direction, and when bearing radial load, additional axial force is caused.
