View:      Tag(s):Deep groove ball bearing is a common type of rolling bearing

Deep groove ball bearing is a common type of rolling bearing. The basic deep groove ball bearing has an outer ring, an inner ring, a set of steel balls and a set of retaining frame.

Deep groove ball bearing is mainly used to bear pure radial load, but also can bear radial load and axial load at the same time. When it only bears pure radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can bear large axial load. The friction coefficient of deep groove ball bearing is very small, and the limit speed is also very high. Especially in the high-speed operation condition with large axial load, the deep groove ball bearing has more advantages than the thrust ball bearing.

Compared with other types, deep groove ball bearing is easy to achieve higher manufacturing accuracy, so it is easy to produce in series and in large quantities with low manufacturing cost. In addition to the basic type, deep groove ball bearing also has various variant structures, such as: deep groove ball bearing with dust cover; deep groove ball bearing with rubber sealing ring; deep groove ball bearing with stop groove; deep groove ball bearing with large load capacity with ball loading gap; double row deep groove ball bearing.
