The axial clearance inside the bearing can be achieved by moving the axial position of the outer ring.

1. Adjusting gasket method:

A group of soft material (soft steel sheet or elastic paper) gaskets are filled between the bearing end cover and the end face of the bearing seat; When adjusting, don’t put the gasket on the bearing end cover, tighten the screws on the bearing end cover evenly, and rotate the shaft by hand until the bearing rolling body contacts the outer ring and there is no clearance inside the shaft; Then measure the clearance between the bearing end cover and the end face of the bearing seat, plus the axial clearance required by the normal operation of the bearing; This is the total thickness of the gasket to be filled, and then fill the prepared gasket between the bearing end cover and the end face of the bearing seat, and finally tighten the screw.

2 adjusting bolt method:

The pressure ring is pressed on the outer ring of the bearing and pressurized with adjusting bolts; Before pressure adjustment, first measure the pitch of the adjusting bolt, and then tighten the adjusting bolt slowly until there is no clearance inside the bearing, and then calculate the corresponding rotation Angle of the adjusting bolt. For example, if the pitch is 1.5mm and the clearance required by the normal operation of the bearing is required, the rotation Angle required to adjust the bolt is 3600×0.15 / L.5 =360; At this time, turn the adjusting bolt 360, and the bearing can obtain an axial clearance of 0.5mm, and then fix it with stop gaskets.
