What are the differences between rolling bearings and plain bearings?
Two, compared with the sliding bearing, deep groove ball bearings shortcomings:1, vibration and noise;2. Radial dimensions larger than plain bearings;3 、 poor ability to withstand impact loading;4 、 under high speed and heavy load, the bearing life is low.
4, for the same size of the shaft diameter, the rolling bearing is wider than the sliding bearing, so that the axial structure of the machine is compact;5, a high degree of standardization, mass production, consumption of lubricants less, easy to seal, easy to maintain, do not need to use non-ferrous metals, low cost.
2, radial clearance is relatively small, radial angular contact bearings can be pre tightened, can be used to eliminate pre clearance clearance, high precision operation;3, under normal conditions, the efficiency of rolling bearings and liquid power lubrication bearings, but the mixed lubrication bearings higher;
