Function and test requirements for bearing steel balls for automobiles

- Jul 20, 2018-

Automobile bearing steel ball is a very important basic component. To a certain extent, especially the precision industrial steel ball plays a very important role in the development of the national economy. The bearing steel ball for automobile will often need under some special conditions. The steel balls of special materials are used to complete the functions required in different environments. In fact, some special material steel balls have been widely used in various fields of the national economy, including 9Cr18, 3Cr13 stainless steel, copper, aluminum and titanium. Alloy steel and agate, glass, ceramic balls, etc.


Automotive bearing steel ball is a very important part of the bearing, and it is also the most used rolling element in the bearing industry. The quality of its products will directly affect its bearing quality. The post-process of steel ball production is the automatic cleaning and automatic appearance of the steel ball. Testing (automatic rejection of non-conforming products), automatic rust prevention, and counting packaging are all key factors affecting the quality of steel balls.


The inspection of the appearance of the bearing steel ball for automobiles is an indispensable process in the processing of steel balls. The appearance inspection of the products mainly includes the detection of surface scratches, rust, surface spots and the like. Steel ball production methods generally include forging, rolling, semi-solid forming and casting.
