Single row-Products-LEXON Bearings

Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. And it can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of non-separable design, and the shoulders on both sides of the inner and outer rings are different in height. In order to improve the load capacity of the bearing, the shoulder on one side will be processed lower so that the bearing can be loaded with more steel balls.

Double row angular contact ball bearings can withstand larger radial loads, mainly combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. The tiltability between the inner and outer rings of the double row angular contact ball bearing is mainly used to limit the bidirectional axial displacement of the shaft and the housing. The allowable tilt angle depends on the internal clearance of the bearing, bearing size, internal design and acting on it. The force and moment on the bearing, and the maximum allowable inclination angle should ensure that no excessive additional stress is generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time cause the bearing's running accuracy to decrease and the running noise to increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages. Pay attention to the installation of double row angular contact ball bearings. Although the bearing can withstand two-way axial loads, if there is a gap for the ball on one side, care should be taken not to allow the main axial load to pass through the gap on the side of the groove. When the bearing is used, care should be taken to make the side raceway without the ball notch bear the main load.
