ABSTRACT:
A combined bearing, pulley and shield assembly that is temporarily unitized prior to being installed on a cylindrical shaft support. A bearing having inner and outer races with an annular space between the races is molded into the hub off the pulley with a pair of shields joined to the pulley in covering relation to the annular space. The shields are joined to the pulley by frangible tabs molded integrally with the pulley. When the pulley assembly is installed, the shields are precisely positioned and fixed to the inner race. Therefore, the tabs fracture in response to initial relative rotation of the pulley and inner race to allow free subsequent relative rotation.
