Abstract

A cage-guided seal is provided with an annular support body, formed preferably from sheet metal, and punched-out retention sections that are adapted to engage the side ring of a standard commercial cage. The peripheral edges of the support body extend close to the sealing surfaces of the inner and outer bearing races and are provided with sealing lips of vulcanized elastomers that engage the inner and outer bearing races.
