Characteristic Description Of Angular Contact Ball Bearings

1. Introduction and application of angular contact ball bearings

Angular contact ball bearings are radial thrust ball bearings. Because more steel balls can be loaded, their radial bearing capacity is greater than that of ordinary ball bearings, and they can also bear a large axial load or pure axial load at the same time. The working speed is similar to the deep groove ball bearing and the supporting rigidity is stronger, but it requires accurate installation and is very sensitive to the axis misalignment error. It is generally not used to bear radial load alone, but must bring additional shafts while bearing radial load. to the load. From VXO angular contact ball bearing supplier, There are many variants of angular contact ball bearings, and they are widely used. They are often made into three series with contact angles of 15°, 25° and 40°. The larger the contact angle, the higher the axial load capacity. contact angle is appropriate.

2. Characteristics of Angular Contact Ball Bearings

Double row angular contact ball bearing and precision angular contact bearings are mostly used in pairs for small-span rigid double-support shafts or precision spindles. When using, carefully adjust the clearance and change the axial distance between the inner and outer rings of the bearing to adjust the internal clearance of the bearing. Installing several sets of bearings in parallel and giving a certain amount of pre-interference can improve the rigidity of the linear motion bearing system.

Angular contact ball bearings can only bear the axial load in one direction, and other bearings need to be configured to offset their additional axial force. Axial load, and has strong axial limit ability in two directions, two sets of bearings are generally installed in pairs with their outer ring wide end faces opposite (back-to-back) or narrow end faces (face-to-face). The rigidity of the back-to-back mounted bearing system is good. In order to facilitate installation in pairs or groups, some bearing factories supply equal bearings in pairs, groups of three and groups of four(four point contact ball bearings), so that the same batch of bearings supplied in this way have good processing consistency, and the load is more uniform during use. The axial forces cancel each other out completely.

There are two types of angular contact ball bearings: separable and non-detachable. Separable bearings are used for limited installation conditions, requiring the outer ring or inner ring to be removed from the complete set of bearings for separate installation. Due to the separation type angular contact Ball bearings are widely used in magneto, so they are also called magneto bearings. High speed linear bearings have a variety of locks on the inner ring, which can be adapted to higher speeds.
