Thrust Roller Bearings
Thrust ball bearings are designed to withstand thrust loads during high-speed operation, and are composed of washer-shaped ferrules with ball rolling raceway grooves. Because the ferrule 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 bear axial load, but cannot bear radial load.

Composition:
Thrust ball bearing is composed of three parts: seat ring, shaft ring and steel ball cage assembly. The shaft ring matched with the shaft is called the seat ring, and the housing ring matched with the housing.
Type: According to the force, it can be divided into one-way thrust ball bearings and two-way thrust ball bearings. One-way thrust ball bearings can bear one-way axial load. The two-way thrust ball bearing can bear two-way axial load, in which the shaft ring and the shaft are matched. The mounting surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the influence of installation errors. Thrust ball bearings cannot bear radial load, and the limit speed is low.
Features:
1. Available in one-way and two-way types
2. In order to allow installation errors, whether it is one-way or two-way, you can choose the spherical self-aligning spherical seat cushion type or the spherical seat ring type.
3. High-quality steel-use ultra-clean steel that can extend the life of the bearing by up to 80%
4. Advanced grease technology lubricant technology can extend the life of grease and improve bearing performance
5. High-grade steel ball-quiet and smooth when rotating at high speed
6. With the ferrule in the option, installation errors can be tolerated.

Application:
Only suitable for parts that bear 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 separated and can be assembled and disassembled separately.
