Seal assemblies and methods that include a seal lip that comprises an extended portion with generally constant cross-sectional width for low and generally constant friction during wear are described. The seal lip is loaded against a dynamic member by the aid of a spring energizer. The extended portion of the seal lip maintains constant torque resistance during movement of the dynamic member.
