NACHI thrust ball bearings are separable bearings, categorized into single-direction thrust ball bearings and double-direction thrust ball bearings based on their structural design. Single-direction thrust ball bearings can withstand axial loads in one direction, while double-direction thrust ball bearings can handle axial loads in both directions. Neither type can support radial loads. Thrust ball bearings also feature a structure with a seat pad. Since the mounting surface of the seat pad is spherical, the bearing possesses self-aligning capability, reducing the impact of installation errors. Thrust ball bearings are primarily used in industries such as automotive and machine tools.

NACHI thrust ball bearings can be broadly categorized into two types:

Single-direction thrust ball bearings

Double-direction thrust ball bearings

Single-direction thrust ball bearings:

Comprising an inner ring, an outer ring, and a ball-cage assembly. These bearings are separable, allowing the inner ring, outer ring, and ball-cage assembly to be installed independently. They are available in three types:

Thrust ball bearings with flat outer rings

Thrust ball bearings with self-aligning outer rings

Thrust ball bearings with self-aligning outer rings and self-aligning washers

Single-direction thrust ball bearings primarily support axial loads in one direction and provide axial positioning in that direction.

Double-direction thrust ball bearings:

Comprising an inner ring, two outer rings, a center ring, and a ball-cage assembly. The bearing is separable, allowing the inner ring, outer rings, and ball-cage assembly to be installed independently. Available in three types:

Thrust ball bearings with flat housing rings

Thrust ball bearings with self-aligning housing rings

Thrust ball bearings with self-aligning housing rings and self-aligning washers

Double-direction thrust ball bearings can support axial loads in both directions and provide axial positioning in both directions.
