NACHI thrust ball bearing is a kind of separated bearing, which can be divided into one-way thrust ball bearing and two-way thrust ball bearing according to its structure. One-way thrust ball bearing can bear axial load in one direction and two-way thrust ball bearing can bear axial load in two directions. They are not capable of withstanding radial loads. The thrust ball bearing is also provided with a seat cushion structure. Since the mounting surface of the seat cushion is spherical, the bearing has the centering performance, which can reduce the impact of installation error. The thrust ball bearing is mainly used in automobile, machine tool and other industries.
The NACHI thrust ball bearing can be roughly divided into two types:
One-way thrust ball bearing
Bi-directional thrust ball bearing
One-way thrust ball bearing:
Consists of a shaft race, a seat race, and a ball - cage assembly. The bearing is detachable, and the shaft ring, seat ring, steel ball - cage assembly can be installed separately. It can be divided into three types:
Thrust ball bearing with plain race
Thrust ball bearing with self-aligning race
Thrust ball bearing with aligning seat ring and aligning seat washer
One-way thrust ball bearing is mainly used to bear unidirectional axial load and perform axial positioning in single direction.
Bi-directional thrust ball bearing:
Consists of one shaft ring, two seat rings, one intermediate shaft ring and ball - cage assembly. The bearing is detachable, and the shaft ring, seat ring, steel ball - cage assembly can be installed separately. It can be divided into three types:
Thrust ball bearing with plain race
Thrust ball bearing with self-aligning race
Thrust ball bearing with aligning seat ring and aligning seat washer
The bearing of two-way thrust ball bearing can bear two-way axial load and conduct two-way axial positioning.
