Abstract
A resilient pad having a base with two side arms and two side lips for resiliently holding the base on a pedestal wear plate, the pad being configured with dome shaped portions disposed substantially perpendicular to the direction of the pad and being spaced apart from each other, where the pad, when installed with a pedestal wear plate serves to improve the force load handling and preferably re-distributes the load bearing surface from the edges and center of the adapter to the flat load bearing surface of the adapter, thus eliminating load on areas that have no support. Because the spring arms do not depend on bending of the base for their resiliency, the pad of the invention provides improved service stress capabilities and allows for longer life of the wear plate.
