Working principle:
Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load. When it is only under radial load, the contact Angle is zero. When the deep groove ball bearing has a larger radial clearance, it has the performance of angular contact bearing and can withstand larger axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is very high.
Main applications of deep groove ball bearing:
Transmission, instruments, electric machines, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.
Deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.
It mainly bears pure radial loads, but also can bear joint loads. When it is subjected to pure radial load, its contact Angle is zero. When it has a larger radial game, that is, it has angular contact bearing performance, which can withstand a larger axial load. Deep groove ball bearing has small friction coefficient and high limit speed, so it has more advantages than thrust bearing when axial load is rotating at high speed. But because its aligning performance is limited, the concentricity of bearing installation should be high, otherwise it will affect the balance of its operation, increase the bearing stress, and thus shorten the working life.
Deep groove ball bearing simple structure, compared with other easy to achieve high precision, so can be mass production. In addition to the conventional models, it also has a variety of structural variations, such as deep groove ball bearing with dust cover, deep groove ball bearing with rubber ring and deep groove ball bearing with a stop groove and so on.
