  42CrMo Piston Rod   is manufactured with the highest quality raw materials and the latest machinery, and has passed strict quality inspection. The structure is strong, durable, high tensile strength and mirror surface, which can be widely used in various mechanical equipment. The surface of the 42crmo  chrome-plated piston rod  has been specially ground and treated with a hard chrome plating process. It has a mirror-polished finish and is resistant to friction and corrosion. The piston rod can be used as a guide rod and a pole for various  cylinders , oil cylinders, packaging machines, woodworking machinery, textile machinery, printing and dyeing machinery, die casting machines, injection molding machines and the like.

  Hydraulic cylinders work by using hydraulic fluid (usually oil) to create pressure.  There is a  cylinder rod  which is connected to a piston.  This moves back and forth inside a  cylinder barrel .  One end of the barrel is capped (closed).  The other end of the barrel has the cylinder head or gland.  The piston rod will come out of the cylinder through here.   The piston rod material  42CrMo4 cylinder rod  with the material number 1.7225 is suitable for high-dynamic applications. Due to the material's high stability very high forces can be transmitted, e.g. for small connecting threads with large piston rods. Hard chrome plating means that an especially thick chrome layer is applied after the pre-honing and before finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV. Hard chrome plated piston rods can be used between -15°C and 200°C.
