Deep groove ball bearing is the most common type of rolling bearing.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. There are two types of deep groove ball bearing, single row and double row, deep groove ball structure is also divided into sealed and open two kinds of structure, open refers to the bearing without sealing structure, sealing type deep groove ball is divided into dust seal and oil seal. The dust proof sealing cover is made of steel plate stamping, which only prevents dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease spillover in the bearing.
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.
