Abstract
A sealing shield, particularly for rolling bearings, of the type wherein relatively soft, elastic peripheral portions are secured to a relatively rigid intermediate portion; the intermediate portion consisting of a single rigid annular insert formed from a synthetic plastic polymer; and the relatively soft peripheral portions being preferably in the form of independent elements co-molded on to the annular insert and formed from a mixture of an elastomer and the same synthetic plastic polymer from which the annular insert is formed. In a preferred embodiment, the annular insert has a trapezoidal radial cross-section.
