Description

Technical Field

[0001] The utility model relates to the technical field of angular contact ball bearings, in particular to a stamped angular contact ball bearing for a steering gear. Background Art

[0002] As the name implies, angular contact bearings are a type of bearing. Angular contact ball bearings can bear radial loads and axial loads at the same time and can work at higher speeds. The larger the contact angle, the higher the axial load capacity. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and the perpendicular line to the bearing axis.
