  I. Introduction In the field of modern mechanical engineering,  bearings  play a vital role, and  thrust ball bearings  have been widely used in many equipments due to their unique structure and performance advantages. II. Structural features 1. Basic composition Thrust ball bearings are mainly composed of a shaft ring, a seat ring and a set of steel balls. The shaft ring is usually installed on the shaft, and the seat ring is installed in the housing hole of the machine. Steel balls are the core components for transmitting loads, and they are held between the raceways formed by the shaft washer and the seat washer. 2. Contact mode Thrust ball bearings are point contact structures. This contact mode enables them to effectively disperse pressure when bearing axial loads. The contact point between each steel ball and the shaft ring and seat ring forms a tiny load transfer area, which can withstand large axial forces under the joint action of multiple steel balls...

On July 10, 2025,   the main bearing   independently developed by   ZYS , a subsidiary of SINOMACH, helped a 17MW direct-drive floating offshore wind turbine roll off the production line in Fuqing, Fujian. This is the world's largest single-unit power and largest wind rotor diameter direct-drive floating offshore wind turbine that has rolled off the production line. ZYS  main bearings  include two sets of  single-row tapered roller bearings  with a maximum outer diameter of 3425mm. During the development of the bearings, a systematic contact fatigue life test of the material was carried out, and a full transmission chain simulation model was built. After repeated iterations and comparisons of more than 100 design schemes, the bearing contact angle and rolling element diameter, length, and shaping amount were optimally matched. In addition, the bearing surface coating technology was studied in conjunction with Tsinghua University, which can effectively ...

The   clearance standards  of   ceramic bearings  are the same as those of   ordinary bearings , which are mainly divided into radial clearance and axial clearance. Radial clearance refers to the amount of movement of the other ring from one extreme position to the other extreme position relative to the fixed ring in the radial direction when one ring is fixed without load. Axial clearance refers to the amount of axial movement of one ring from one extreme position to another relative to the fixed ring when there is no load and one ring is fixed. The clearance standard of ceramic bearings is the same as that of ordinary bearings. The selection of clearance mainly considers the following aspects: 1. Influence of fit: The fit between the inner ring of the bearing and the shaft, and the fit between the outer ring and the housing hole will affect the size of the clearance. An interference fit will reduce the clearance, while a clearance fit will increase the clearan...

In   wind turbine equipment , the   main bearing   is one of the key components to ensure the stable operation of the wind turbine. In order to adapt to different working conditions, manufacturers usually use a variety of materials to make these bearings. The following are several common wind turbine main bearing materials and their characteristics: 1. Steel material Steel is the most popular choice for manufacturing wind turbine main bearings. Commonly used steel grades include 40Cr and GCr15, which are known for their excellent strength and hardness, and can effectively cope with the pressure and vibration during high-speed rotation. In addition, steel is cost-effective and sufficient to meet the application requirements of most wind turbine main bearings. 2. Heat-resistant steel For bearings that need to work in high-speed and high-temperature environments, heat-resistant steel is an ideal choice. This type of steel has good high-temperature strength and corrosion resi...
