Adjustment of axial clearance of spherical roller bearings

wallpapers Tech 2021-03-01

The inner ring of the bearings is positioned by the shaft shoulder, and the outer ring is pre-tightened by the bearing glands on both sides. The axial clearance of the bearing is adjusted by the pre-tightening force of the bearing glands on both sides, taking into account the bearing clearance caused by heat To reduce, there should be a certain amount of clearance in the axial direction of the bearing. There is no relevant national standard for the axial clearance of the bearing.

 

In practice, the axial clearance is less affected by factors such as interference assembly and load operation. Therefore, during installation, the original clearance of the bearing is generally adjusted according to the standard.

 

Adjustment of radial clearance of spherical roller bearing

 

The radial clearance of the bearing plays a vital role in the stable operation of the bearing. For the radial clearance of the bearing, GB/T4604-2006 has related standards, so in specific applications, only need to look up the table. The upper and lower limits of the radial clearance of the bearing.
