Deep groove ball bearing is one of the most widely used rolling bearings. Its characteristics are small friction resistance, high speed, can be used to bear radial load or radial and axial action of the combined load on the parts, but also can be used to bear axial load on the parts.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearing, single row and double row, deep groove ball structure also divided into two types of sealed and open structure, open type refers to the bearing without seal structure, sealed deep groove ball is divided into dustproof seal and oil-proof seal. The dustproof seal cover material is steel sheet stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease from spilling inside the bearing.When the speed is high and thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other bearings of the same size and size, this kind of bearing has low friction coefficient and high limit speed. However, it is not shock resistant and is not suitable for heavy load.
After the deep groove ball bearing is mounted on the shaft, within the axial clearance range of the bearing, the axial displacement of the shaft or housing can be limited in both directions, so the axial positioning can be made in both directions. In addition, this type of bearing also has a certain ability to adjust the center, when relative to the shell hole inclined 2 '~ 10', still can work normally, but has a certain impact on the bearing life. | | | | | I.D | | O.D | | W | |
