The assembly of plane bearing is the basic operation of fitter assembly and repair, and the adjustment and pre tightening of clearance is an important part of IKO bearing assembly. Accurately grasping the process concept of clearance adjustment and pre tightening and correctly using this process method in the assembly work is the guarantee of the assembly quality of plane bearing.
The clearance of plane bearing refers to the large amount of activity made by the other ring along the radial or axial direction when one ring is fixed, so the clearance is divided into radial clearance and axial clearance. When assembling IKO bearing, the clearance shall not be too large or too small.
Most bearings with large load and high rotation accuracy requirements work in the state of no clearance or even a small amount of interference.In this case, it is necessary to preload the bearing during assembly. The clearance adjustment and pre tightening are usually completed by making appropriate axial relative displacement of the inner ring to the outer ring.
