Aluminum Pneumatic Cylinder Tube
- Precision Bore Tolerance: Aluminum pneumatic cylinder tubes are extruded and honed to achieve high inner roundness and surface smoothness, ensuring minimal friction and optimal air sealing.
- High-Quality Aluminium Alloys: Manufactured from 6063-T5 and 6061-T6 alloys, combining light weight, machinability, and corrosion resistance ideal for pneumatic applications.
- Hard Anodized Interior Surface: Enhanced wear resistance and surface hardness extend the lifespan of piston seals and reduce maintenance.
- Dimensional Customization: Available in outer diameters from 20 mm to 200 mm, wall thickness from 1 mm to 10 mm, with cut-to-length and tolerance control services.
- Compatible with Global Cylinder Standards: Supports ISO 6431, ISO 15552, and JIS cylinder designs, enabling direct fitment and global interchangeability.
- Low Friction and Leak Prevention: Inner surface roughness up to Ra 0.4 μm ensures smooth piston travel and long-term sealing performance.
- Lightweight but Durable: Provides excellent strength-to-weight ratio, reducing overall system load without compromising structural integrity.

Aluminum Pneumatic Cylinder Tube-FAQ's
What is an aluminum pneumatic cylinder tube?
It is an aluminum profile with a honed inner surface and anodized coating, used as the main body of pneumatic air cylinders.
Which alloys do you use?
We primarily use 6063-T5 for standard cylinders and 6061-T6 for high-pressure or structural applications.
Do you support hard anodizing?
Yes, we offer both hard and clear anodized finishes based on durability or appearance requirements.
What are the standard sizes?
Inner diameters range from 20 mm to 160 mm, with wall thickness from 1 mm to 10 mm.
Is your tubing compatible with ISO pneumatic standards?
Yes, we manufacture tubes compatible with ISO 6431, ISO 15552, and JIS standards.
Can I order cut-to-length tubes?
Absolutely-we offer precision cutting and machining services to reduce assembly time.
What’s the typical surface finish?
The inner bore is honed to Ra ≤ 0.4 μm, and outer surface is anodized or polished for corrosion resistance.
