    CHAIN
  • ROCKMAN chains are manufactured in state of the art facilities
  • Advanced automation machines ensure that the parts are assembled to the correct closed tolerances giving ROCKMAN chains a precise fitment in application
  • Chains are pre loaded at 50% minimum ultimate tensile strength which is specifically important for applications involving fixed center to center distance sprockets. This 50% proof loading eliminates initial elongation and increases chain fatigue resistance
  • Plate components are Shot Peened with control intensity and speed which allows the creation of compressive stress in the plates to avoid propagation of fatigue cracks
  • ROCKMAN Chains uses proprietary lubricants and vacuumed greasing processes designed to fully penetrate the bearing surfaces between pin and bushes ensuring higher wear resistance in automotive application
