deck crane bearing Cage effect

the role of deck crane bearing

1, to support the shaft and parts on the shaft, to keep the rotating precision of shaft;

2, to reduce friction during rotation and wear;

Four, slim ball bearing‍ bearing selection principle

1, ball bearings than the limit speed of roller bearing high, priority should be given to the selection of ball bearing;

2, at high speed to the selection of bearing, ultra light, super light and light series (inner diameter and outer diameter, the smaller, the rolling body is light and small, centrifugal inertial force is small);

3, cage materials has a great influence on bearing speed, solid cage than stamping cage to allow higher speed;

The speed limit is 4, thrust bearing is very low, when working at high speed, if the axial load is not very big, can use the angular contact ball bearings to Taper roller bearings‍ bear pure axial force;

5, if the speed exceeds the bearing sample, can be used to improve the tolerance level, increasing the clearance, the circulating cooling method.
