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

1. Adjust the gasket method:

Fill a set of soft material (soft steel sheets or elastic paper) gaskets between the bearing end cover and the end face of the bearing seat; when adjusting, install the bearing end cover without placing the gaskets, and tighten the screws on the bearing end cover evenly while adjusting. screw while turning the shaft by hand until the bearing rolling element contacts the outer ring and there is no gap inside the shaft; at this time, measure the gap between the bearing end cover and the end face of the bearing seat, plus the shaft required for normal operation of the bearing. This is the total thickness of the gasket required. Then fill the prepared gasket between the bearing end cover and the end face of the bearing seat, and finally tighten the screws.

2. Adjust the bolt method:

Press the pressing ring on the outer ring of the bearing and pressurize it with the adjusting bolt; before adjusting the pressure, first measure the pitch of the adjusting bolt, then slowly tighten the adjusting bolt until there is no gap inside the bearing, and then calculate the adjustment The corresponding rotation angle of the bolt. For example, if the pitch is 1.5mm and the clearance required for normal operation of the bearing is required, then the required rotation angle of the adjusting bolt is 3600×0.15/l.5=360; then, if the adjusting bolt is reversed 360 degrees, the bearing will obtain an axial clearance of 0.5mm. , and then fix it with stop washers.
