Abstract

A bearing seal assembly includes at least one seal unit and at least one pulse wheel attached to the seal unit in an interference-fit and/or a materially bonded manner. The seal unit may include a radially outer member surrounding a radially inner member, the radially inner member may have a cylindrical seal surface and a flange projecting radially outwardly from an end of the seal surface and the radially outer member may have a metal profile element at least partially covered by an elastomer body that defines a first seal lip that directly contacts the cylindrical seal surface of the radially inner member. The pulse wheel may be attached to the radially outer member by a radially inwardly directed flange of the metal profile element overlying a radially outer edge of the pulse wheel.
