ARO Premair Series Compact Cylinders: High-Force, Small-Footprint Actuation

Engineered for Space-Critical OEM and MRO Applications

In modern manufacturing, space is a premium commodity. The ARO Premair Series Compact Cylinders are engineered to deliver maximum force in the smallest possible footprint. Whether you are an OEM integrating components into a new machine or an MRO professional replacing worn actuators, the Premair Series provides the reliability of full-sized cylinders in a fraction of the space

The Premair Advantage: Rugged Construction, Minimal Size

The Premair Series is built to withstand industrial environments while maintaining a lightweight, low-profile geometry. By utilizing high-strength aluminum alloys and corrosion-resistant stainless steel, ARO has created a cylinder that balances durability with a high power-to-weight ratio.

• Standard Features across the Premair Series:

  • Space-Saving Design: Ideal for manifold mounting and tight machine enclosures.

  • Hard Chrome Plated Stainless Steel Rods: Provides superior wear resistance and protection against corrosion.

  • Self-Lubricating Bushings: Features Duralon® non-metallic bushings for higher load capacities and zero "slip-stick."

  • Repairable Construction: Designed for long-term serviceability with available seal kits.

  • ISO 9001 Certified Manufacturing: Ensures consistent quality and dimensional accuracy.

Premair Square Compact (Metric)

The Premair Square Series is available in 10 bore sizes ranging from 12mm to 100mm. These cylinders are the preferred choice for electronic assembly and precision positioning.

• Auto-Switch Ready: Integrated machined grooves allow for low-profile solid-state sensors without increasing the cylinder's footprint.

• Interchangeability: Directly replaces leading square compact cylinders from other manufacturers.

Premair Round Compact (Inch/Interchangeable)

The Premair Round Series (1-1/8” to 4” bores) is built for rugged durability using stainless steel tie bolts and aluminum spacers to lock the cylinder heads securely.

• Smooth Interior Finish: The heavy-walled aluminum barrel is precision-machined for an extremely smooth surface, extending the life of the Buna-N or optional Viton seals.

• Versatile Action Styles: Available in Double Acting, Single Acting (Spring Return), and Reverse Acting (Spring Extend) models.
