XW stainless steel bearings in metric and inch sizes are produced to Normal tolerances as standard. Some sizes are also available to customer specifications.

AISI 440C/9G18

1% C, 17% Cr, .5% Mo
A hardened, martensitic stainless steel, 440C is the standard choice for a wide range of military, medical and commercial applications. 440C is suitable for applications which require corrosion resistance in a thermal range from room to mid-hot.

300/1G18Ni9 Series Stainless Steel

In a semi-precision grade bearing, 300 series stainless steel can be chosen for improved corrosion resistance over 440C. These materials are not heat treated so load capacity is significantly less than HT 52100 & 440C. It can be used for both rings and balls or SS rings with ceramic balls. 300 series stainless steel offers excellent corrosion resistance to water and excellent to good resistance when exposed to certain common acids. This material can be an excellent choice for food processing and packaging, beverage. Other applications may include marine and vacuum processes. 300 series stainless steel is also a common material used for ribbon and crown type retainers. 300 series stainless steels are generally considered non-magnetic.
