Grande Extreme - Model EXP 316 - Stainless Steel Triangular Round Flanged Bearing Units - Brochure

Paint, corrosion protection is not needed because EXG flanged housings are made of stainless steel (grade 316) which is rustproof and resistant to corrosion from sea water and almost all chemicals. Another great advantage of stainless steel bearing housing material is that they have a much greater tensile strength and not fragile like the cast iron flange bearing units.
