Abstract:
A pressure nitrided stainless steel hybrid ball bearing having an inner ring, an outer ring, and rolling elements disposed therebetween. The pressure nitrided stainless steel hybrid bearing has one or more component(s) made from a pressure nitrided stainless steel material. The pressure nitrided stainless steel hybrid bearing used with a refrigerant lubrication for chiller applications leads to a very long useful life time.
