Stainless steel deep groove ball bearings are corrosion resistant when exposed to moisture and several other media. They can accommodate radial loads and axial loads in both directions. These bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel.
Stainless steel bearings not only have low vibration, low noise, high precision rotation performance, but also has its own unique performance: wide adaptation environment, acid, corrosion resistance, in sea water, river water, distilled water, dilute nitric acid, maritime climate , steam and other corrosive media work; especially with temperature characteristics, can work at -253 ºC ~ 350 ºC.
