FAQ – Hydraulic Chrome Rod
Q1: What is the typical lifespan of your hard chrome plated rods in hydraulic cylinders?
A: Depending on the application and operating environment, our rods can last over 1 million strokes with proper maintenance.
Q2: Can you offer induction hardened rods as well?
A: Yes, we offer induction hardened chrome rods for applications needing high impact resistance.
Q3: Is your CK45 hydraulic chrome rod suitable for telescopic cylinders?
A: Absolutely. Our hollow piston rod version is specifically designed for telescopic use.
Q4: Do you support third-party inspection before shipment?
A: Yes, SGS, BV, or customer-nominated inspections are welcome.
Q5: What’s the difference between CK45 and SAE1045 chrome rods?
A: They are nearly equivalent in chemical composition and performance; the main difference lies in regional standards (EN vs. AISI).
