Abstract
A seal assembly for a wheel spindle bearing is provided for use between its two relatively rotatable coaxial parts, and thus to seal the bearing chamber. The seal assembly includes an inner and outer annular casing, with at least one of the casings including a contact land. An annular sealing disk forms an extended area slip sealing interface against the contact land. The sealing disk is cross sectionally flat or L-shaped, and is urged into sealing contact with the contact land by an annular elastomeric spring defining a channel in cross section. The channel of the spring is formed by inner and outer axially extending resilient rings. The seal assembly can also include a second annular sealing disk that is urged into cooperating sealing contact with a second contact land.
