High Precision Crossed Roller Bearing Clearance Is Usually Measured?
Oct 25, 2016

One, crossed roller bearing clearance is divided into radial clearance and axial clearance

Radial clearance means: non-preload, radial load bearing radial clearance: radial direction at any angle, when the load is not outer ring relative to the inner ring radial eccentricity from one extreme position, moving in the opposite limit position of the arithmetic average value of radial distance.

Axial clearance means: non-preload, bearing in the axial loads in either direction, the axial internal clearance as follows: when there is no load, one ring with respect to another set of rings, from one shaft to limit the axial position to the opposite limit position from average.

Second, cross-roller bearing clearance measurement

Radial clearance method

1, law

A, turn the bearing, the bearings should be stable and flexible without jamming.

B, hand shaking bearings, radial clearance is only 0.01mm, the top amount of axial movement of the bearing, there are 0.10~0.15 mm. This method is dedicated to cross-roller bearing.

Axial clearance means: non-preload, bearing in the axial loads in either direction, the axial internal clearance as follows: when there is no load, one ring with respect to another set of rings, from one shaft to limit the axial position to the opposite limit position from average.
