Our hard chromium plating on piston rods provides exceptional surface hardness, smoothness, and wear resistance, ensuring long-lasting performance in demanding hydraulic and pneumatic systems. Manufactured with high-quality steel substrates, the rods undergo advanced grinding, polishing, and hard chrome plating processes. This ensures excellent corrosion protection, reduced friction, and extended service life, making them ideal for heavy-duty hydraulic cylinders and precision machinery.

 

 

• High Surface Hardness-Hard chrome plating improves hardness up to HRC 55–60, resisting scratches and wear.
• Corrosion Resistance-The plating acts as a protective barrier against rust, oxidation, and harsh working environments.
• Smooth Surface Finish – Reduces seal damage and improves hydraulic system efficiency.
• Improved Fatigue Strength – Extends working life under repeated stress and pressure cycles.
• Cost-Effective Performance – Reduced downtime and maintenance costs for industrial users.
