Abstract
Abstract A rotating face sealing gasket, particularly for use on tracked vehicles, constituted by a pair of facing metal rings in mutual sliding contact, and a pair of rings of resilient material mounted on the outside of each metal ring and forming a seal one against a rotating surface and the other against a fixed surface of the vehicle. A mutual slide-proof connection between each metal ring and the resilient ring rigid therewith is obtained by providing a plurality of ribs on the one to cooperate with an equal number of grooves in the other.
