What is the bearing?
The part that supports a relatively rotating shaft is called a bearing. In the case of bronze bores, the shaft is usually rotated. There are also shafts that rotate without rotation of the housing, such as automotive hub bearings. Bearing is divided into rolling bearings and plain bearings.
Bearing the use of:
1, deep groove ball bearings
Deep groove ball bearings with simple structure, easy to use, is the largest production volume, the application of the most extensive range of brass bushings of a class of bearings. It is mainly used to bear a radial load, but also can withstand a certain axial load. When the bearing radial clearance increases, with angular contact bearing function, can withstand greater axial load.
2, aligning ball bearings
Self-aligning ball bearings have just two columns seeking, there are two inner raceway, outer raceway spherical shape, with self-aligning performance. It can automatically compensate for the concentricity error caused by the ramps of the shaft and the deformation of the housing, which is suitable for the parts that support the seat hole can not guarantee strict coaxiality. The bearing is mainly made of resin-based steel ball holding ring by the radial load, radial load at the same time, also can withstand a small amount of axial load, usually not for pure axial load, such as to withstand pure axial load, only A ball just force.
3, angular contact ball bearings
Angular contact ball bearings high speed limit, can withstand both longitudinal and axial loads, but also can withstand pure axial load, the axial load capacity determined by the contact angle, and with the contact angle increases.
4, cylindrical roller bearings
Cylindrical roller bearing roller is usually guided by the two flanges of a bearing ring, cage. Roller and the guide ring form a group, can be separated from the other bearing rings, are separable bearings. This bearing installation, demolition more convenient, especially when required. Outer ring and shaft. Housing are interference fit even more advantages.
