The common contact angles of angular contact bearings are 15°, 25° and 40°, and the corresponding suffix codes are C, AC and B. Among them, the bearing with the 15° angle mainly bears radial force and a small part of the axial force, which is suitable for high speed and high precision occasions; the bearing with the 25° angle is subjected to a slightly larger axial force than the 15° angle; the bearing with the 40° angle are subjected to greater axial forces and are suitable for large axial loads and vertical installation of equipment.

We classify and introduce some common angular contact ball bearings according to the number of ball rows, whether it is separable bearing, whether having filling slot, countinnerd outer ring or countinnerd inner ring, and contact angle α (the contact angle refers to the angle between tthe normal of the contact point between the ball and the raceway and the radial plane).

Including: 1. Type 10000, cylindrical inner self-aligning ball bearing and type 10000K, tapered inner self-aligning ball bearing, those bearings mainly bears radial load, and also can bear a small amount of axial load at the same time, which means that they can not bear axial load alone.

Self-aligning ball bearing is the rolling bearing with balls as rolling elements and having a spherical raceway in the outer ring enabling angular alignment within the raceway. Self-aligning ball bearing is particularly suitable for applications where deflection is caused by improper installation or shaft bending. This bearing generally adopts the stamped cage or the polyamide cage, in which the polyamide cage is indicated by the suffix code G in the bearing code.

Including 1, Open deep groove ball bearing type 60000, which mainly bears pure radial load, and also can bear a certain axial load. When only the radial load is subjected, the contact angle is zero; When the radial clearance is increased, it has the function as angular contact ball bearing, which can bear large axial load. This type has simple structure, easy to use and wide application.
