A: deep groove ball bearing five features: 1 and in bearing radial clearance increases, angular contact ball bearings, can withstand the properties of the two directions of alternating axial load. 2 and on the structure of deep groove ball bearings with each of the contractor for the ball cross-sectional about one-third of the perimeter of the continuous groove type roll. It is mainly used in radial load, also can withstand the axial load. 3, simple structure, low cost, easy to achieve high precision manufacturing. 4 and friction small, high speed. 5, generally USES stamping wave form, inner than 200mm keep running at high speed bearings, or by car. Keep making entities, 2: deep groove ball bearing advantage: 1 radial clearance is small, the angular contact bearings available pre-tightening usable pre-tightening force to eliminate clearance, high precision, 2 most rolling bearings can simultaneously by radial and axial load, bearing structure is simple, 3 for the size of the width of the rolling bearing trunnion, than sliding bearing is small, can make the machine's axial compact structure, Four general conditions, rolling bearing and efficiency of fluid dynamic lubrication bearing is mixed lubrication, but to some high bearing, 5 don't need useful nonferrous metals, 6 a high degree of standardization and batch production, low cost, 7. Consumes less convenient seal lubricants, easy maintenance,
