Working Principle

The basic 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 bearings: single row and double row. The deep groove ball structure is also divided into two types: sealed and open structure. Open type refers to the bearing without sealing structure. Dust sealing cover material for steel plate stamping, only to simply prevent dust into the bearing raceway. Oil-proof type is a contact oil seal, which can effectively prevent the grease spillage in the bearing.

Deep groove ball bearing structure is simple, compared with other types of easy to achieve higher manufacturing accuracy, so it is convenient for series of mass production, manufacturing cost is low, the use is very common. In addition to the basic type, there are various variant structures of deep groove ball bearings, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber sealing ring, deep groove ball bearings with stop groove, deep groove ball bearings with large load capacity with ball notch, double row deep groove ball bearings.

Deep groove ball bearings mainly bear radial load, can also bear radial load and axial load at the same time. When it only bears radial load, the contact Angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can bear a large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.
