S1206 stainless steel thrust ball bearing
Stainless steel thrust ball bearings are divided into one-way thrust ball and two-way thrust ball. Both types of bearings can transfer large axial loads, but not radial loads. In addition to the structure with flat seat ring, thrust ball bearing with spherical seat ring and cushion structure.
Stainless steel thrust ball bearing is a separate type of bearing, according to its structure can be divided into one-way thrust ball and two-way thrust ball bearing. 1. One-way thrust ball bearing can bear axial load in one direction; 2. Two-way thrust ball bearing can bear axial load in two directions. None of them can withstand radial loads. Plane thrust ball bearing gasket material is bearing steel or stainless steel, divided into groove and no groove.
Retainer material is divided into stainless steel and copper, plane thrust ball is separable bearing, contact Angle 90, can be installed separately, can only withstand axial load. The ultimate speed of thrust bearing is low, steel ball plus centrifugal force squeeze to the outside of raceway, easy to scratch, but not suitable for high-speed operation. One-way thrust bearing can bear one-way axial load, two-way bearing can bear two-way axial load, thrust ball bearing with spherical seat ring has centering performance, can eliminate the influence of installation error.
Installation principle: plane bearing mainly bears axial load in the assembly, which is widely used. Although the installation and operation of plane bearing are relatively simple, errors often occur in the actual maintenance, that is, the mounting position of the tight ring and loose ring of the bearing is not correct, so that the bearing loses its function and the shaft neck is quickly worn out. The inner ring of the tight ring is in a transitional fit with the shaft neck. When the shaft rotates, it drives the tight ring and causes friction with the end face of the stationary part. When the axial force (Fx) is applied, the friction torque will be greater than the inner diameter matching resistance moment, leading to forced rotation of the tight ring and the shaft matching surface and aggravating the wear of the shaft neck.
