What Is A Deep Groove Ball Bearing

PDF

Deep groove ball bearings are suitable for high speed or even very high speed operation, and very durable, without regular maintenance. The friction coefficient of this kind of bearing is small, the limit speed is high, the size range and form vary, applied in the precision instrument, low-noise motor, automobile, motorcycle and general machinery industry, is the most widely used type of bearing in the machinery industry. The main bearing radial load, can also withstand a certain amount of axial load.
