What is the difference between stainless steel bearing ball and steel bearing ball?

- Apr 12, 2019-

The steel bearing ball generally has a relatively high carbon content during operation, and enhances wear resistance when used. Stainless steel generally has a high Cr content of more than 12%, mainly for utilizing its corrosion resistance. Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in materials, but also have stricter control on precision in process and precision than ordinary bearings.

 

In the process of working, the steel bearing ball has stable stainless steel bearing, low noise, corrosion resistance and wide application. The bearing ring and rolling element materials are vacuum-quenched and tempered by AISI SUS440C stainless steel (domestic code: 9Cr18Mo, 9Cr18). The frame material of the cage and seal ring is made of AISI304 stainless steel (domestic code: 1Cr18).

 

Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. Choose suitable lubricants, dustproof covers, etc., and can be used in the environment of -60 ° C ~ +300 ° C. Stainless steel deep groove ball bearings resist corrosion caused by moisture and several other media. These single row deep groove ball bearings have the same deep bearing groove as the standard deep groove ball bearings made of carbon chromium (rolling bearing) steel, and the degree of fit between the bearing race and the ball is extremely high. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and load capacity.
