Thrust ball bearings are designed to withstand thrust loads at high speeds and consist of a washer-like ferrule with ball rolling groove grooves. Since the ferrule is a cushion shape, the thrust ball bearing is divided into two types: a flat base cushion type and a self-aligning spherical seat cushion type. In addition, this bearing can withstand axial loads but cannot withstand radial loads.
composition
Thrust ball bearing composition: Thrust ball bearing is composed of three parts: seat ring, shaft ring and steel ball cage assembly. The so-called shaft ring that cooperates with the shaft, and the seat ring that cooperates with the outer casing.
kind:
According to the force condition, the one-way thrust ball bearing and the two-way thrust ball bearing are divided.
Thrust ball bearing
One-way thrust ball bearings can withstand one-way axial loads. The two-way thrust ball bearing can withstand two-way axial load, in which the shaft ring is matched with the shaft. The mounting surface of the seat is spherical and has a self-aligning performance, which can reduce the influence of installation errors. Thrust ball bearings cannot withstand radial loads and have lower limit speeds.
Characteristics
1. Available in one-way and two-way types
2. In order to allow installation errors, either spherical or spherical, you can choose either a spherical or spherical seat type or a spherical seat type.
3. High-quality steel ― Ultra-clean steel with up to 80% longer bearing life
4. High grease technology - NSK's lubricant technology extends grease life and improves bearing performance
5. High grade steel ball ― Quiet and smooth when turning at high speed
6. Use the ferrules in the option to allow for installation errors.
use
The use of thrust ball bearings: only suitable for parts with a low axial load and low speed, such as crane hooks, vertical pumps, vertical centrifuges, jacks, low speed reducers, etc. The shaft ring, race and rolling element of the bearing are separated and can be assembled and disassembled separately.
