Mini motorcycle wheel bearings/deep groove ball beairng 627ZZ
Deep groove ball bearings are generally composed of a pair of rings and a set of cage, a group of rigid ball and a set of cage structure, deep groove ball bearing type code is 6. is the most common production, the most widely used class of bearings. Grooved ball bearing structure is simple, easy to use, is the largest production volume, bear a certain axial load.When the bearing radial clearance increases, with angular contact ball bearing function, can withstand greater axial load.
Deep groove ball bearings are mainly used to withstand the pure radial load, but also can bear the radial load and axial load, when it only bear the pure radial load, the contact angle is zero. When the deep groove ball bearings have a large radial clearance, with angular contact bearing performance, can withstand greater axial load. Deep groove ball bearing friction coefficient is very small, the limit speed is also high, especially in the Axial load is very high speed operating conditions, deep groove ball bearings than thrust ball bearings more superiority.Compared with the same size of other types of bearings, such bearings friction factor is small, high speed limit. Axial load can be used with thrust bearings in the case of thrust ball bearings. After deep groove ball bearings are mounted on the shaft, the axial displacement of the shaft or housing can be limited to the axial clearance of the bearing. The hole and the shaft (or the outer ring to the inner ring) are relatively tilted (no more than 8-16 according to the clearance to determine) can still work normally.However, there is a tilt exists, it is necessary to reduce the bearing life.
Deep groove ball bearings and other types of bearings of the same size, the friction loss is minimal, the higher the speed limit, the higher the speed should not be used in the case of thrust ball bearings, such bearings can withstand pure axial load. Precision, and the use of bakelite, bronze, hard aluminum and other material solid cage, the speed can also be improved.
Application:
Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery. With a dust cover and a deep groove ball with a ring
