How to choose the clearance of imported bearings

The selection of imported bearing clearance mainly depends on two aspects: on the one hand, tighter cooperation; in the inner and outer ring, the temperature difference is large, the demand decline conflict torque and the deep groove ball bearing accepts large axial load or needs to improve the centering function; Large clearance group. On the other hand, when the rotation precision demand is high or the axial displacement is strictly restricted; a small clearance group should be selected.
Pay attention to the following elements related to the import bearing clearance;
1. Cooperation between the inner ring of the imported bearing and the shaft.
2. Cooperation between the outer ring of the imported bearing and the hole of the outer casing.
3, the influence of temperature. The heat generated will lead to the internal temperature of the bearing; then the expansion of the shaft, bearing housing and bearing parts. The clearance can be increased or decreased. 馊 [鲇谥岷 岢 岢 岢 牟 牟 牟 约 约 爸岢 岢 岢 岢 岢 С 胁 涞 涞 涞 涞 涞 涞 涞 涞
