Abstract
A nonrotatable seal assembly is provided for use with a conventional pillow block housing to form a positive barrier to prevent the entry of foreign contamination. The seal assembly has a thin body portion provided with two peripheral grooves each adapted to receive a rib on a wall of the pillow block housing with a deformable sealing member on the outer periphery of said body portion between the grooves. Said seal assembly has a pin extending into the wall of the pillow block housing to prevent relative rotation therebetween. A thicker body portion of the seal assembly contains a lubrication recess between first and second seals with a conventional lubrication fitting communicating with said recess.
