Ball Bearing

Deep Groove Ball Bearings,Easy to use and Large output make deep groove ball bearing be the most popular. It is mainly used to bear radial load as well as a certain axial load. When its radial clearance is larger, it will have the function of angular contact ball bearings and could bear large axial load. Compared with other bearings with the same size, deep groove ball bearing has smaller friction coefficient and high limiting speed. We could use this kind of bearings, when the speed is too high for the thrust bearings.

Thrust ball bearings are separated-type bearings, and its shaft ring,seat ring,cage and steel balls could be separated to each other. This type of bearings could only afford axial load. One-way thrust ball bearings can only support axial load in one direction, and two-way thrust ball bearings can withstand axial loads in both directions; thrust ball bearings could not restrict radial shaft displacement and its speed is very low

Self-aligning ball bearings have two rows of steel balls and two races in the inner ring. The outer ring is in spherical shape, which makes it have the feature of auto-aligning. It can automatically compensate for the error from the shaft deflection and the shell deformation of the coaxial. Self-aligning ball bearings are mainly used to bear radical load, also it could bear a certain axial load, normally, when they bear pure axial load, they just have one row of steel ball.

Angular contact ball bearings have high speed limits and are able to support both radial load and axial load. It can afford pure axial load, and its load capacity is decided by its contact angular, which will increase, when the contact angular is larger. Single row angular contact ball bearings could only afford the axial load in one direction, so we should use them in pairs. Two rows angular contact ball bearings could afford large two-way joint load and moment load, and it could limit the bi-directional axial displacement of the shell and shaft with a 30°contact angular. Angular contact ball bearings installed in pairs could withstand two-way co-axial load and pure radial load. . Series configuration can only afford a single direction axial load, and the other two configurations can withstand axial load in either direction. This type of bearings is generally submitted in pairs by the manufacturers to match combination of users, which will increase the entire group as single bearing support stiffness and rotation accuracy.
