Piston rod is main parts of oil drilling rig mud pumps. The large end of the piston rod is connected to the power end of the mud pump through the clamp to transmit power; the small end is mounted with a mud pump piston, and generate pressure through reciprocating motion in mud pump liner.


The piston rod manufactured by our company is forged from 35CrMo material. It has corrosion-resistant, high-density, low-wear surface, which reduces the deformation of the sealing packing and prolongs the service life of the sealing sleeve and the piston top sealing ring. This piston rod is also equipped with a piston nut. 


The surface treatment types are: Parkerizing, plating chrome and nickel.


The products we produce are oriented by user's demand, improve performance cost, reduce production cost, save labor cost and improve production efficiency.


Thereby, the corrosion resistance of the surface is improved, and the generation or expansion of fatigue cracks can be delayed, thereby increasing the fatigue strength of the cylinder rod. Through roll forming, a cold hardened layer is formed on the rolled surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the abrasion resistance of the cylinder rod surface and avoiding burns caused by grinding. After rolling, the surface roughness value is reduced, which can improve the mating properties. At the same time, the friction damage to the seal ring or seal during the movement of the cylinder rod piston is reduced, and the overall service life of the cylinder is improved. Rolling process is an efficient and high-quality process measure.


Piston rods are mainly used in hydraulic and pneumatic, engineering machinery, automobile manufacturing piston rods, plastic machinery guide posts, packaging machinery, printing machinery rollers, textile machinery, conveying machinery axis, linear optical axis for linear movement.
