ABSTRACT:
A seal, particularly for antifriction bearings, which includes two facing L-shaped, rigid sheet metal parts. The axially directed arm of each sealing part, has on its radially outer surface, a thin elastic covering layer which is scraped off over part of its axial length during assembly of the seal into the space between the bearing rings. The scraped off part of the covering is stored in a groove in the interior of the adjacent bearing ring. Two of the L-shaped parts are provided and their open sides face toward each other. Sealing lips seal the space between them.
