Deep groove ball bearings and structural features of the classification

Compared with plain bearings, deep groove ball bearings of the excellent	Compared with plain bearings, deep groove ball bearings of the inferior
1, the general conditions, the efficiency and fluid dynamic bearing lubrication bearing considerable, but higher than the number of hybrid bearings;	1, less able to withstand impact loading;
2, radial clearance is small, angular contact bearings can be used to preload cardiac preload can be used to eliminate clearance, operation and high precision;	2, high-speed heavy load bearing lower life;
3, for the same size shaft, ball bearing sliding bearing smaller than the width, the axial machine can compact;	3, vibration and noise is relatively large;
4, most of the rolling bearing can also be radial and axial load bearing structure so simple;	4, the radial dimension than the sliding bearing large;
5, less lubricant consumption, easy to seal, easy to maintain;
6, no useful in non-ferrous metals;
7, high standardization, mass production, low cost;
