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.
In The Same Working Conditions Of The Same Type Of Rolling Bearing, Usually The Larger The Size, The Longer Its Life.
A:In the same type of rolling bearing under the same working conditions, the larger the size is, the longer the life is, is right, according to the pressure theorem, the smaller the contact surface is, the greater the pressure (pressure) is (such as jack), similarly, the small rolling bearing inside and outside the longitude is very small, the ball direct longitude is small, and the bearing inside and outside the contact surface is small, the greater the force it bears, It and the bearing inside and outside the friction force is also large; Large rolling bearing inside and outside by the increase, the ball by the increase and the number of direct, and the bearing inside and outside by the contact surface will increase, the ball to bear the force is reduced, it and the bearing inside and outside by the friction force is small, so high-power equipment with large bearings.
