ABSTRACT:
The present invention is generally directed to a bearing assembly suitable for use in a wet or harsh chemical environment. The bearing assembly includes a bearing housing that is resistant to corrosion, oxidation, contamination and deterioration when exposed to water, bacteria and various chemicals. Specifically, the bearing housing in accordance with the present invention is made from sintered stainless steel. In one embodiment, the housing can also be impregnated with a polymeric sealant which prevents the housing from entrapping bacteria and chemicals to which it may be exposed.
