Select bearing axial fastening on several factors:
(1) acting on the bearing load magnitude and direction
(2) the level of the bearing rpm
(3) type of bearing
(4) the position of the bearings in the shaft or casing.
The greater the axial load, the higher the speed of the bearing, the axial fastening increasingly reliable.
For different types of bearings, it is necessary to use different types of the axial fastening means. On single row angular contact ball bearings or tapered roller bearings, they belong to the type of adjustable axial clearance. Will be ready to adjust the clearance is completed, the axial fastening. Therefore, the use of the shaft or casing hole shoulder block unidirectional support, without having to use a special axial fastening means, as the radial direction of the fixed support bearing, the inner and outer ring must be fixed axially as the compensation axis thermal elongation swimming support, just fixed them ferrule ferrule swimming is not fixed, to be installed in swimming support is separable short cylindrical roller bearings, needle roller bearings, two sets of The circle must be fastened.
