Compared with sliding bearing, deep groove ball bearing and miniature ball bearing, general conditions of deep groove ball bearing, the rolling Needle Roller Bearing efficiency and hydrodynamic bearing lubricated bearings, but a mixed lubrication bearing to the high number of;
1, ability to withstand the impact load is poor;
2, the radial clearance is relatively small, angular contact radial bearings can be preloaded available pretightening force to eliminate the clearance, high running precision; high speed heavy load bearing life is low;
3, for the same size of Thin section bearings the shaft diameter, bearing width smaller than the sliding bearing, the axial structure of machine is compact; vibration and noise;
4, most of the rolling bearing can be both radial and axial load, so the bearing assembly has the advantages of simple structure; the radial size than the sliding bearing;
5, the consumption of lubricant, which is convenient for sealing, easy maintenance;
6, do not need useful nonferrous linear ball bearing metal;
7, a high degree of standardization, mass production, low cost;
