Honed Tubes
Honed Tubes are precision hydraulic cylinders used in fluid power applications. These tubes undergo a honing process that ensures exceptional surface finish and dimensional accuracy, making them ideal for pneumatic and hydraulic cylinder barrels. Manufactured from high-quality seamless steel pipes, honed tubes offer outstanding wear resistance, strength, and smooth internal surfaces for long service life and reliable performance.
- Smooth inner surface finish for improved sealing and low friction
- Excellent dimensional accuracy and roundness
- High tensile strength and fatigue resistance
- Ideal for hydraulic and pneumatic cylinder applications
- Corrosion and wear-resistant performance
