Deep groove ball bearings are the most commonly used rolling bearings. It is simple in structure and easy to use. Mainly used to bear radial load, but when increasing the radial bearing clearance, with a certain angular contact ball bearing performance, can withstand radial and axial joint load. In high speed and should not be used when the thrust ball bearings can also be used to withstand pure axial load. Compared with other types of bearings of the same size, the friction coefficient of such bearings is small, high speed limit. Impatience impatience is not suitable for heavy loads. Deep groove ball bearings mounted on the shaft, the axial clearance in the bearing range, can limit the axial displacement of the shaft or housing in both directions, so the two-way axial positioning. In addition, this kind of bearing also has a certain self-aligning ability, when relative to the housing hole tilt 2 '~ 10', can still work, but the bearing life has a certain impact. Deep groove ball bearing cage for the most punching steel plate cage, large bearings and more metal car body cage. Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery. With dust cover and seal ring deep groove ball bearing assembly has been filled with the right amount of grease, should not be heated before installation do not have to clean, no lubrication during use, to adapt to operating temperature -30 ℃ to +120 ℃ between.
