•AISI 304 stainless steel ball bearings have much greater corrosion resistance than those made of SAE 52100 bearing steel or AISI 440C stainless steel
•Heat resistant grease is used in AISI 304 and AISI 440C stainless steel ball bearings
•AISI 440C stainless steel bearings have a high resistance to corrosion and chemicals, plus high stability in high temperatures
