Piston Rod

Piston Rod

We manufacture high-quality hard chrome plated piston rods designed for superior performance, durability, and corrosion resistance in hydraulic and pneumatic applications. Our piston rods are engineered to meet demanding operating conditions where surface finish, hardness, and dimensional accuracy are critical.

Using carefully selected alloy and carbon steels, our piston rods undergo precision machining followed by advanced hard chrome plating (or other specified coatings) to achieve excellent wear resistance and low friction characteristics. The plating process is tightly controlled to ensure uniform thickness, strong adhesion, and long service life.

Manufacturing & Quality Control
Manufacturing & Quality Control

    Each piston rod is manufactured through a controlled process that includes turning, grinding, plating, polishing, and rigorous inspection. Surface finish, plating thickness, adhesion, and straightness are checked to ensure compliance with international standards and customer specifications.

Piston Rod Repair Services

We provide reliable piston rod repair and refurbishment services to restore damaged or worn rods to optimal working condition. Our repair solutions help extend component life, reduce downtime, and offer a cost-effective alternative to replacement without compromising performance or safety.

Comprehensive Repair Process

Our piston rod repair process includes:

  • Inspection and assessment of wear, corrosion, scoring, or bending
  • Precision straightening and machining, where required
  • Metal build-up and re-grinding to original dimensions (With suitable WPS and PQR)
  • Re-plating (hard chrome or specified coating) for wear and corrosion resistance
  • Final polishing to achieve the required surface finish

Each repaired piston rod is restored to meet functional and dimensional requirements for proper sealing and long service life


Quality & Reliability

All repaired piston rods undergo strict quality checks, including straightness, diameter tolerance, surface finish, and plating integrity. Our controlled processes ensure consistent performance in demanding hydraulic and industrial applications.

Type of Work

Rebuilding, Grinding & Plating
When to Opt for
  • Deep scoring & scratches on OD
Cost Saving & Advantages
  • Rod End-Cap need not be changed
  • Piston Rod salvaged to original size
  • Full life expectancy as original
Grinding & Plating
When to Opt for
  • Minor scoring & scratches on OD
  • Removal of rust due to peeling of plating
  • Jerky reciprocation of cylinder assembly
Cost Saving & Advantages
  • Piston Rod salvaged in a very short time
  • Rod End-Cap need not be changed
  • Piston Rod as good as new
  • Full life expectancy as original

FAQ

1. When should piston rod replacement be considered?
Piston rod replacement is recommended when there is heavy scoring, deep scratches on the outer diameter (OD), or when the rod is severely bent. In such cases, structural integrity is compromised, and replacement ensures safe and reliable hydraulic operation
2. What is rebuilding, grinding, and plating of a piston rod?
Rebuilding, grinding, and plating is a restoration process used when a piston rod has deep surface damage but is not structurally failed. The rod is ground, replated, and restored to its original size, allowing reuse without changing the rod end-cap while maintaining full service life.
3. When is grinding and plating sufficient for piston rod repair?
Grinding and plating is suitable for minor scoring, surface scratches, rust formation due to plating peel-off, or jerky cylinder movement. This process quickly restores surface finish and performance, making the piston rod function like new.
