Various types of bearings have different characteristics due to different designs.There is no fixed mode for bearing type selection due to the specific mounting position of bearing and the variability and complexity of application occasions.In order to adapt to the specific installation position and application conditions of a certain host, the following factors should be considered comprehensively:
1. Dimension space
Mechanical design, generally determine the size of the shaft first, and then choose the bearing according to the size of the shaft.Generally, ball bearings are used for small shafts.Cylindrical roller bearings, spherical roller bearings, tapered roller bearings (ball bearings are sometimes used) are used for the big shaft.
If the radial space of bearing mounting position is restricted, bearings with smaller radial section height should be used.If the axial space of the bearing mounting position is restricted, the bearing with a smaller width can be used.
