Inch size SSUCP203 miniature stainless steel pillow block bearing unit is consist of Stainless steel insert bearing SSUC203 And Stainless steel bearing housing SSP203, The bearing unit bore is 17 mm which is the same dimension with the mounted bearing unit UCP203 With cast iron housing.

Stainless steel bearing unit is composed of a stainless steel insert bearing and a stainless steel pillow block. The stainless steel bearing rings and rolling elements are made of 440C stainless steel (9Cr18Mo, 9Cr18). They are vacuum quenched and tempered, and the cage and seal ring skeleton are used. The material is 304 stainless steel (0Cr18Ni9). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. Choose appropriate lubricants and dust caps, etc., and can be used in the environment of -60 ℃ ~ + 300 ℃. Stainless steel bearing unit are resistant to moisture and corrosion caused by several other media. This type of ball bearing unit is similar to the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel. It has a deep bearing raceway groove and the degree of cooperation between the bearing raceway and the ball is extremely high. Stainless steel bearings unit are widely used in food processing, medical equipment, and pharmaceutical machinery because of their high mechanical strength and large load capacity.
