This bearing housing is made of precision-machined pure stainless steel, which offers superior resistance to acids, alkalis, salt spray corrosion, and mechanical shock compared to aluminum bearing housings. This makes it an ideal choice for harsh environments such as offshore drilling platforms, coastal power plants, or high-concentration chemical gases. Its internal fluororubber O-rings ensure perfect physical airtightness, preventing high-temperature oil mist leakage from the bearing housing, and fully comply with the American Petroleum Institute (API) 670 standard recommendations.
