Ss2321 Stainless Steel Self Aligning Ball Bearings

Ss2321 Stainless Steel Self Aligning Ball Bearings include three kinds of stainless steel materials. They are 440c stainless steel, 304 stainless steel and 316L stainless steel.

Among them, 440c stainless steel have the strongest hardness, and this type of stainless steel bearing has the best mechanical properties. 304 stainless steel has good corrosion resistance and very little magnetic properties. 316L stainless steel has best corrosion resistance and is almost nonmagnetic.
