What is the miniature thrust ball bearings?

/in /by

Miniature Thrust Ball Bearings are only one kinds of Thrust Ball Bearings, But smaller size than normally thrust ball bearings, It’s a separable bearing with a contact angle of 90, which can be installed separately and can only bear the axial load. The limit speed of the miniature one-way thrust bearing is low, and the steel ball is squeezed to the outside of the raceway by centrifugal force, which is easy to be scratched, but it is not suitable for high-speed operation. One-way miniature thrust bearing can bear one-way axial load, and two-way bearing can bear two-way axial load. Miniature Thrust ball bearing with spherical seat ring has self-aligning performance, which can eliminate the influence of installation error.

Miniature thrust ball bearings are designed to withstand thrust loads during high-speed operation, and it consist of a washer-like ferrule with a ball-rolling raceway groove. Since the ferrule is in the form of a seat cushion, the thrust ball bearing is divided into two types: flat seat cushion type and self-aligning spherical seat cushion type. In addition, this bearing can withstand axial loads, but not radial loads.

Miniature thrust ball bearing structure: The material of the bearing retainer is divided into stainless steel and copper, and the material of the plane thrust ball bearing is bearing steel or stainless steel, which is divided into with groove and without groove.

The use of miniature thrust ball bearings: It is only suitable for parts that bear an axial load on one side and have a low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft washer, seat washer and rolling elements of the bearing are separated and can be assembled and disassembled separately.
