Thrust ball bearing composition: Thrust ball bearing consists of three parts: seat ring, shaft washer and steel ball cage assembly. The shaft ring matched with the shaft, and the seat ring matched with the housing.
According to the force, it is 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.
In order to tolerate installation errors, whether it is one-way or two-way, we all choose spherical self-aligning spherical seat cushion type or spherical seat ring type. For the design of thrust ball bearings, we use ultra-clean steel that can extend the life of the bearing by up to 80%.
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.
High-quality grease can extend the life of the bearing and improve the performance of the bearing. The purpose of thrust ball bearings: 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.
Thrust ball bearing as the thrust bearing, this kinds of thrust bearing have more the other type of design.
-- Cylindrical thrust roller bearings consist of small cylindrical rollers arranged flat with their axes pointing to the axis of the bearing. They give very good carrying capacity and are cheap, but tend to wear due to the differences in radial speed and friction which is higher than with ball bearings.
-- Tapered roller thrust bearings consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing. The length of the roller and the diameter of the wide and the narrow ends and the angle of rollers need to be carefully calculated to provide the correct taper so that each end of the roller rolls smoothly on the bearing face without skidding. These are the type most commonly used in automotive applications (to support the wheels of a motor car for example), where they are used in pairs to accommodate axial thrust in either direction, as well as radial loads. They can support greater thrust loads than the ball type due to the larger contact area, but are more expensive to manufacture.
-- Spherical roller thrust bearings use asymmetrical rollers of spherical shape, rolling inside a house washer with a raceway with spherical inner shape. They can accommodate combined radial and axial loads and also accommodate misalignment of the shafts. They are often used together with radial spherical roller bearings. Spherical roller thrust bearings offer the highest load rating density of all thrust bearings.
