Get to know thrust ball bearings in detail


The thrust ball bearing adopts a design that can accept thrust load during high-speed operation, and is composed of a washer-shaped ring with a ball rolling raceway groove. Because the ring is in the shape of a cushion, thrust ball bearings are divided into two types: flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can accept axial load but not radial load.

Thrust ball bearing consists of three parts: seat ring, shaft ring and steel ball holder assembly. The shaft ring matched with the shaft and the housing ring matched with the housing can be divided into one-way thrust ball bearings and two-way thrust ball bearings according to the force condition. Thrust ball bearings, thrust ball bearings, and one-way thrust ball bearings, can accept one-way axial direction. load. Two-way thrust ball bearings can accept two-way axial loads, in which the shaft ring matches the shaft.

The device surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the influence of device error. Thrust ball bearings cannot accept radial load, and the limited speed is low. There are two types of thrust ball bearings, one-way and two-way. In order to allow installation errors, thrust ball bearings can choose spherical self-aligning spherical seats whether it is one-way or two-way. Cushion type or with spherical seat ring type.

High-quality steel—Using ultra-clean steel that can extend the life of the bearing by 80%. 4. Highly smooth grease technology—NSK's smoothing agent technology can extend the life of the grease and improve the performance of the bearing. 5. High-grade steel balls—when rotating at high speeds Quiet and smooth 6. The ferrule in the application option can allow device errors.

Uses Edit the use of thrust ball bearings: only suitable for parts that accept one side of axial load and low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft ring, seat ring and rolling element of the bearing are separate and can be assembled and disassembled separately.
