Hobs FUSION consist of two metal bushes and the rubber elastic insert therebetween. The outer and inner metal sleeve , forming a hinge frame , made of meeting the highest requirements of steel and have a thermal diffusion zinc coating , which gives better adhesion of the rubber vulcanization. Used rubber compound has high strength characteristics simultaneously with sufficient flexibility . The quality of material prevents premature failure of the bushing and its peeling from the metal cage , which allows the hinge to operate under extreme conditions , as the compressive and torsional . Check the condition of Bushes at least once every 50 thousand miles.
