What is a Honed Tube?
A honed tube is created by machining a cold-drawn seamless tube or DOM (Drawn Over Mandrel) tube and then honing the inside surface to improve roundness, straightness, and surface finish. The honing process eliminates surface imperfections, ensuring the inner surface achieves a smooth Ra finish, typically between Ra 0.2 to Ra 0.8 μm.
Key Features of Our Honed Tubes
✅ Mirror-Like Finish: Ultra-smooth internal surface for seamless piston movement
✅ Precision Tolerances: ID tolerances maintained within H8/H9 class
✅ High Roundness & Straightness: Perfect geometry ensures zero leakage and friction
✅ Corrosion Resistance: Available in chrome-plated, phosphate-coated, or stainless steel
✅ Long Service Life: Exceptional wear resistance and low maintenance
Materials Used
Our honed tubes are manufactured from high-grade materials including:
ST52 / E355 (DIN 2391 / EN 10305) – Most popular material for hydraulic applications
1020 / 1045 / 4140 Steel – For industrial-grade strength and performance
Stainless Steel 304 / 316 – For corrosion-resistant applications
Alloy Steel – For high-pressure, heavy-duty systems
Each material is selected based on the end-use requirements, such as pressure ratings, environmental exposure, and temperature fluctuations.
Our honed tubes are designed for use in a wide range of industries:
➤ Hydraulic Cylinder Tubes
Used in construction equipment, presses, forklifts, and loaders.
➤ Pneumatic Cylinder Tubes
Ideal for air-powered actuators and automation systems.
➤ Industrial Machinery

Honed Tube Manufacturing Process
The honing process is the heart of honed tube production. Here is a step-by-step breakdown:
Selection of Raw Material: High-quality cold-drawn seamless steel tubes, usually made from carbon or alloy steel such as ST52, E355, or SAE 1026.
Pre-machining: The tubes are first cut, deburred, and cleaned.
Cold Drawing: This process increases dimensional accuracy and mechanical properties.
Honing: Using abrasive stones mounted on a rotating mandrel, the inner surface is finely ground to achieve the desired finish and roundness.
Inspection & Testing: Every honed tube undergoes rigorous testing for hardness, roughness, straightness, and roundness.
Protective Coating & Packaging: The tubes are coated with anti-rust oil and packaged securely for shipping.
How to Maintain Honed Tubes
To ensure the longevity of your honed tubes:
Use Clean Hydraulic Fluids
Check for Wear or Scoring Periodically
Keep the Tubes Free of Contaminants
Ensure Proper Alignment in Cylinder Assemblies
Store in Dry, Covered Areas to Prevent Rusting
Regular inspection and maintenance can significantly improve the efficiency and service life of your machinery.
