Product Description
The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation, and is composed of a washer like ring with a ball rolling raceway groove. Due to the cushion shaped collar, thrust ball bearings are divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, this type of bearing can withstand axial loads, but cannot withstand radial loads.
Classification of thrust ball bearings:
Unidirectional thrust ball bearings and bidirectional thrust ball bearings.
1.Unidirectional thrust ball bearings can withstand unidirectional axial loads.
2.Bidirectional thrust ball bearings can withstand bidirectional axial loads, where the shaft ring fits with the shaft. The bearing with a spherical installation surface of the seat ring has centering performance, which can reduce the impact of installation errors. The thrust ball bearing cannot withstand radial loads and has a lower limit speed.
Characteristics of thrust ball bearings:
1. There are two types available: unidirectional and bidirectional.
2 In order to allow for installation errors, whether it is unidirectional or bidirectional, the spherical centering spherical seat cushion type or the spherical seat ring type can be selected.
3. High quality steel - use ultra clean steel that can extend the bearing life by up to 80% Highly advanced grease technology - NSK's lubricant technology can extend the lifespan of grease and improve bearing performance High grade steel ball - quiet and smooth when rotating at high speed 6 Using the ferrules in the options allows for installation errors.

Precautions for assembly of thrust ball bearings:
There are two key points in the assembly of thrust ball bearings.
1.One is the control of the quality of the cage and steel ball pressing;
2.the other is the control of the nominal height T after bearing assembly.
In addition, due to the fact that both the shaft and seat rings can be separated, there is a management issue of preventing mixed installation of imported bearing parts.
The M-type stamping cage uses a curved edge assembly mold. After pressing, the steel ball is required to rotate flexibly in the pocket hole, but it cannot fall off from the pocket hole. The technical regulations should check the movement of the steel ball in the pocket hole.
Pressing the solid cage too deeply can reduce the movement of the steel ball, and the connection between the embossed protrusion and the cage is too small and the strength is insufficient, which can easily lead to the phenomenon of falling blocks and causing the cage to be scrapped.
The difference in inner diameter between the seat ring and the shaft ring of a small thrust ball bearing is very small, and there is no significant difference between the two sets of bearings. In order to prevent the occurrence of mixed sets, it is found that both sets of bearings are seat rings or shaft rings.
