Introduction To Thrust Ball Bearings

Thrust ball bearings are divided into two types: unidirectional and bidirectional. They can only withstand axial loads and must not withstand any radial loads. The thrust bearing is divided into two parts: a tightening ring and a movable ring. The tightening ring is tightly connected to the shaft sleeve, and the movable ring is supported on the bearing seat. Ferrules and rolling elements are usually made of high-strength and wear-resistant rolling bearing steel, and the surface hardness after quenching should reach HRC60-65. Cages are often made of soft steel stamping, and can also be made of copper alloy cloth, adhesive wood, or plastic.
Bidirectional thrust angular contact ball bearing
The contact angle of thrust angle contact ball bearings is generally 60 °. The commonly used thrust angle contact ball bearings are bidirectional thrust angle contact ball bearings, mainly used for precision machine tool spindles. They are generally used in conjunction with double row cylindrical roller bearings and can withstand bidirectional axial loads. They have advantages such as high accuracy, good rigidity, low temperature rise, high speed, and easy assembly and disassembly.
Thrust roller bearing
This includes thrust cylindrical roller bearings, thrust tapered roller bearings, thrust needle roller bearings, and thrust self-aligning roller bearings.
