ABSTRACT:
A one-piece body portion injection molded of polysulfone or similar polymer has mounting portions for securing the bearing housing to a support surface and a transverse bore having a spherically concave annular bearing seat for tiltably supporting a convex outer ring of a bearing. Diametrically opposed axially extending recesses within the bearing seat facilitate insertion of the outer race ring after molding of the body portion. The bearing housing has significantly improved stiffness and resistance to moisture, creep, thermal deflection, chipping and corrosion, making the bearing housing particularly suited for use in the food processing industry.
