Abstract: A method of manufacturing an annular seal includes: providing an intermediate having an annular layer of an elastomeric first material bonded to an annular layer of a second material, the second material different from the first material; and machining the intermediate to form the annular seal having the first and second materials. The intermediate machined to provide a U-shaped profile and is defined by a radially extending wall, an outer flange wall extending axially from the radial wall, and an inner flange wall facing the outer flange wall and extending axially from the radial wall. The annular seal has a seal lip that extends radially inward from the inner flange wall and is formed from the second material. The second material has one or more of: a lower coefficient of friction, a higher heat resistance, a higher wear resistance and/or a higher chemical resistance than the first material.
