About the bearing, many people may not be very clear, and they do not know what it is used for. In fact, it is an important part of mechanical equipment and is widely used in industrial machinery. So what parts are the bearing construction methods? , What are the differences in the bearing structure, the following will give you a detailed analysis.

1. Bearing bushing
1) The inner diameter of the bushing exceeds the maximum value of the rule, that is, the shaft diameter plus the maximum allowable clearance of the bearing;
2) When the outer diameter of the shaft sleeve is less than the minimum value of the specified size and the knurling method cannot meet the quality requirements;
3) When the bushing is burnt or the shaft is held.

Two, split imported bearings
1) When the alloy is seriously worn and its thickness is reduced by more than 1/2;
2) When the serious area of shelling and cracking of the alloy layer is more than 1/3;
3) The bearing alloy layer is severely burned;
4) When the shaft contact angle between the alloy and the bearing is greater than 120o, the contact angle cannot be adjusted by shovel scraping the plane of the shoe mouth or the side clearance is too large to be adjusted.

3. Bearing thin-walled tile
1) The alloy layer is sintered;
2) When the wear of the bearing alloy layer is serious and the bite cannot be tightened by the padding method;
3) When the alloy layer is shelled or cracked;
4) When the wear of the alloy layer is not too serious but cannot guarantee the maintenance distance period;
5) When the alloy layer is worn, the bearing needs to be tightened by the padding method, but the thickness of the gasket exceeds 0.5mm.
