<p>A two-piece cartridge-type seal for wheel bearings and the like. The seal element contains a radial flange having a seal attached thereto and a mounting flange portion. The wear sleeve portion includes a cylindrical flange receivable over a rotary part, and a radial flange having an extension with an inner surface which engages a part of the seal during installation only. In use, the radial flange of the wear sleeve is engaged by a tool, and this radial flange deflects slightly to push the seal element into a desired position of installation, whereupon, when the tool is removed, the radial flange springs back and creates a slight working clearance between these parts.</p> |
