Piston Rods

Product Feature
  • Piston rods made of S45C medium carbon steel. The material conforms to JIS S45C / DIN CK45 / SAE 1045 and JIS S55C.
  • Rods made of SCM440 steel conform to SAE4140.
  • Higher tensile strength after a precision cold drawing process.
  • Wear and corrosion resistance thanks to a hard chrome plating processing.
  • High-frequency hardening processing.

A piston rod is a pivotal component in a shock absorber and a strut. It should deliver the ideal amount of liquid to the seal, reducing the seal’s wear and tear and minimizing the leaking possibility.

Ying-Ching’s piston rods have a high-quality finish and are corrosion- and wear-resistant. They sustain the shock absorber’s frequent movement and ensure durability.
