ABSTRACT:
A sealing shield assembly for a rolling bearing has at least one ring with a seat comprising at least one essentially reinforcing member and an anchoring device made of an elastomeric material for securing the enforcing member in the bearing seat. The reinforcing member includes a peripheral annular sleeve portion shaped like a cylindrical sleeve, and an anchoring device which includes a radially elastically compressible sleeve section made of an elastomeric material. It is secured as a unit to the sleeve portion on a lateral coupling surface thereof, and is adapted to be interposed between the annular sleeve portion and the bearing seat. A plurality of axial grooves are on a separate lateral surface opposite the said coupling surface of the annular sleeve portion. The grooves extend from a continuous annular end portion of the elastomeric sleeve section to a point corresponding to a terminal rim of the annular sleeve portion interrupted by the grooves. The elastomeric sleeve section is capable of interacting radially with interference with the bearing seat.
