Rail is a heavy duty roller bearings, bearing can provide materials processing and other applications with very high loading capacity.
Especially HVBEA series bearings, it for axial clearance of processing system provides a good way.
Below is adjust the eccentric bearing parts to reduce the axial clearance of step: from the faceplate to retrieve all the hexagon screws.
Balanced pressure, in the outer race of bearing down on them at the same time, the eccentric bearing, in order to separate the two bearings.
From the smooth surface of the shell to measure the top of the eccentric bearing one by one.
The eccentric bearing shaft rotate around, to change the height of the bearing shell with smooth surface.
To measure and adjust, until you reach the required distance.
The bearing assembly and tighten all the screws back in the faceplate.
