The Poly Flex Rudder Bearing & Seal System is manufactured specifically for the marine environment. They are extremely strong, dry lubricant impregnated polymer bearings, with nitrile o-rings and grease seal. The grease nipples are stainless steel (including the ball and spring). The bearing housing is a mandrel wound oven cured pre-impregnated epoxy/glass tube.
