  • Publication number: 20070175381
    Abstract: A magnetic wear device including a resilient member and a magnetic member for protecting a wear surface on a material handling device. The resilient member consisting of an upper portion and a lower portion integrally formed together. The upper portion having a top exterior surface, and the lower portion having a bottom surface for contacting with a wear surface on a material handling device. The bottom surface of the lower portion being formed with a recess for receiving and coupling the magnetic member to the resilient member. The magnetic member having an outer magnetic surface for releaseably securing the magnetic member and the resilient member to the wear surface of the material handling device. The magnetic wear device further including a shear plate having an outer edge and an inner circular edge. The outer edge is constructed with one or more notched edges and the inner circular edge defines an aperture for at least partially receiving the resilient member and the magnetic member therein.
