How Skiving & Roller Burnishing Enhance Performance
When it comes to high-performance hydraulic cylinders, H8 skived and roller burnished tubes are a top choice for engineers who demand precision, durability, and smooth operation. But what makes these tubes so reliable?
The Right Steel for the Job
Not all steel is created equal—especially when it comes to hydraulic applications. The best H8 tubes are made from:
High-Quality Carbon Steel (STKM, E355, etc.) – Offers excellent strength-to-weight ratio and machinability.
Alloy Steel (4140, 4340, etc.) – Ideal for high-pressure systems due to superior fatigue resistance.
Stainless Steel (304, 316) – Used in corrosive environments (e.g., marine or chemical industries).
Why does material matter?
Wear Resistance – Harder steels (like alloy grades) last longer under heavy loads.
Machinability – Carbon steel is easier to skive and burnish to ultra-smooth finishes.
Cost Efficiency – STKM/E355 provides a great balance between performance and affordability.
How Skiving & Roller Burnishing Enhance Performance
The H8 process involves two key steps:
- Skiving (Precision Cutting) – A sharp tool removes inner surface imperfections, ensuring a uniform diameter.
- Roller Burnishing (Cold Working) – A hardened roller compresses the tube’s inner wall, creating a mirror-like finish (Ra ≤ 0.2 µm).
Benefits of This Process:
✔ Lower Friction – Smoother surface = better seal performance & less energy loss.
✔ Higher Pressure Resistance – Work-hardened surface resists cracking.
✔ Longer Lifespan – No micro-cracks = reduced wear over time.
Conclusion: The Perfect Match of Material & Process
Choosing the right steel for H8 skived and roller burnished tubes ensures maximum durability and efficiency. Whether you need carbon steel for cost-effective solutions or alloy steel for extreme conditions, the key is pairing the material with precision machining.
