  • Strut wear bands
    Patent number: 9051987
    Abstract: Wear bands for heavy duty struts are disclosed. The wear bands include multiple layers such as a base metal layer sandwiched between an outer layer and an intermediate layer along with a solid lubricant layer disposed opposite the intermediate layer from the base metal layer. The outer layer engages an interior surface of the strut housing, which slidably accommodates a rod. The solid lubricant layer, which is the innermost layer, engages an outer surface of the rod so that the wear band is sandwiched between the rod and the housing and provides a solid lubricant layer for engaging the sliding rod.
