Principle: Deep groove ball bearings are mainly subjected to radial loads, but they can also withstand both radial and axial loads. When it is only subjected to radial load, the contact angle is zero. When the deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the limit rotational speed is also high.
Applications: Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.
