Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple, easy to use. Mainly used to bear the radial load, but when increase the bearing radial clearance, it has a certain angular contact ball bearing performance, can withstand radial, axial joint load. When in High-speed operation should not use thrust bearings, but it also can withstand pure axial load. Compared with other bearings of the same size, this deep groove ball bearing’s friction coefficient is small, the limit speed is high. But impatient impact, not suitable for heavy load.
Deep groove ball bearings consist of an inner ring, outer ring, steel balls and a cage. It is mostly used in carrying radial load, but also constant axial load.
