Leyparts Cylinder Liners

  • Material checked with Quantavac computer controlled analyzers for all elements at a time.
  • To optian an optimal mix of mechanical properties,durability,heat dissipation, wear resistance and ring contact with liners, a critical balance is maintained between carbon, chromium and phosphorus in the raw material.
  • Hardness, especially, is closely monitored since low hardness will lead to faster wear and high hardness to breakage.
  • Bore size and inner/outer dia. checked with high precision electronic/pneumatic gauges.
  • Electronic surface testing is done using Talysurf for optimum surface finish.
  • 100% crack detection with sophisticated crack detection equipment.


  • High strength raw material for longer life.
  • Precision-machining for accurate dimensions to enable easy fitment.
  • Efficient honing pattern and surface finish for adequate lubrication & lesser ring wear.
  • Optimum hardness and porosity for reliable operation.
