WHAT IS A STAINLESS STEEL BEARING?
Stainless steel bearing's ring and rolling element material are AISI SUS440C stainless steel, which is vacuum-quenched and tempered. The stainless steel bearing has stronger rust and corrosion resistance than ordinary bearing steel.
Choose a suitable lubricant, dust cover, etc., 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 due to their high mechanical strength and load capacity.
