Stainless steel ball bearings R168

Demension: 6.35×9.525×3.175mm

The high performance stainless steel ball bearings can provides not onlywith the cleanliness and corrosion

resistance characteristic also withthe high accuracy and excellent wear resistance compare to the

highcarbon chrome steel bearings. The rings and balls are made of thematerial as a standard structure of

stainless steel bearing. The ringsand balls are made of the material AISI440C(9Cr18Mo or 9Cr18), the

cageand the framework of seal adoption the AI304 or AI316, productionaccuracy couldreach ISO standard ABEC-

1 and above, and the vibrationlevel reach Z1 grade and above.

We also can offer non-standard stainless steel ball bearings to meetsome special type needs in engineering.

Compare to high carbon chromemartensite stainless steel bearing. Austenite stainless steel bearingshave

even more excellent corrosion and wear resistance, magnetismresistance. The whole Austenite stainless steel

bearings are made ofAISI SUS316L(316) or SUS304(including inside and outside rings, ballsand cage).
