Characteristics and applications of thrust ball bearings:
There are two types of planar thrust ball bearings: unidirectional and bidirectional. Unidirectional planar thrust ball bearings have steel balls added between a set of raceways, with a contact angle of generally 90 °. They can only withstand unidirectional axial loads and are not suitable for high-speed rotation. This type of bearing can be separated into three pieces, commonly known as a three clip bearing, and both washers have arc-shaped deep grooves for ball rolling.
The bi-directional thrust ball bearing has a middle ring and two outer rings installed on the shaft, and steel balls are added between the middle ring and the outer ring respectively, which can withstand bi-directional axial loads.
There are flat seat types, self-aligning seat types, and seat types with self-aligning washers for the outer ring of flat thrust ball bearings. The cage of unidirectional and bidirectional thrust ball bearings is generally formed by stamping steel plates.
Other special types include thrust self-aligning roller bearings, bidirectional thrust angular contact ball bearings, thrust needle roller bearings, thrust cylindrical roller bearings, etc.
