Thrust ball bearings, also known as thrust bearings, have a structure consisting of the upper, lower ring and roller assembly - center spacing ring. shaft from shaft to bearing. The lower ring is usually fitted tightly with the bearing body and leaned against the bearing shoulder to transmit axial force to the machine body.

Ball bearing is a type of bearing that can be separated from the inner ring, the outer ring, the ring ring with the roller elements individually assembled. They are manufactured in a variety of sizes, including 2 types: 1-way ball bearings and 2-way ball bearings.

Unidirectional shaft ball bearings consist of an outer ring, an inner ring, a roller system, and a spacer. True to its name, unidirectional ball bearings can only withstand axial loads in one direction and therefore only position axially in one direction. The ball bearing cannot withstand any radial load.

The 2-way ball bearing is composed of two spacing rings with rolling elements located between the two outer rings and an inner ring. The inner ring has grooves on both sides while the outer ring has grooves on only one side. These bearings withstand axial forces in both directions and cannot withstand radial forces.

Spindle ball bearings with spacing are usually made of stamped steel for small ball bearings and of monolithic cast brass for large ball bearings. Manufactured bearings guarantee precision in normal operation, in a position where the precision is more demanding, or where a higher rotation speed is required, bearings with higher precision are use.
