The primary seal component includes an elastomeric seal body with a primary sealing lip contacting a first portion of the wear sleeve component, an intermediate excluder lip facing another portion of the wear sleeve, and an outer, excluder seal portion with a cylindrical contact surface. The wear sleeve component has a casing with providing an interior cylindrical contact surface and an elastomeric exterior excluder lip with a seal band portion facing the cylindrical contact surface portion of the outer excluder seal.
