Custom Pneumatic Cylinders

Aluminum Cylinders

If keeping component weight low is top priority, an aluminum cylinder is the perfect solution. Our Class 5N aluminum cylinders are lightweight but are as heavy-duty as the rest of the Nopak family, providing reliable, consistent operation. These low-pressure cylinders are equipped to handle air pressures of up to 250 PSI air or 400 PSI hydraulic and, depending on the seal material chosen, operating temperature up to 400°F. They can be customized in numerous ways, including bore size, mounting style, stroke length, cushioning, component materials, and more. Stainless steel and custom cylinder materials are also available upon request.


  • Available for pneumatic (air) power sources.
  • Piston Seals: Heavy lip design Carboxilated Nitrile construction. Seals are pressure activated and wear-compensating for long life (self-lubricating material).
  • Piston: Precision machined from 6061 – T651 aluminum alloy, provides an excellent bearing surface for extended cylinder life.
  • Piston Rod: Precision machined from high yield, polished and hard chrome-plated steel.
  • Tie Rods: Pre-stressed high carbon steel tie rod construction eliminates axial loading of cylinder tube and maintains compression on tube and end seals.
  • Cylinder Tube: Precision machined from 6063 – T6832 high tensile aluminum alloy and hard coat to 60 Rc for wear resistance and extended cycle life.
  • Permanent Lubrication: Permanently lubricated with Magnalube-G PTFE-based grease on all internal components. This is a non-migratory type high-performance grease providing outstanding service life. No additional lubrication is required.
  • Cushions: Floating cushion seal designed for maximum cushion performance, quick return stroke break-away, and extended life.
  • Rod Seals: Heavy lip design Carboxilated Nitrile construction. Seals are pressure-activated and wear-compensating for long life (self-lubricating material).
  • Head, Cap, and Retainer: Precision machined from high strength 6061-T6 aluminum alloy. Black anodized for corrosion resistance.
