Premair Series Compact Pneumatic Cylinders Information

Features & Benefits

ARO Premair Series: Compact Strength, Proven Reliability

Modern industrial designs demand components that do more with less. The ARO Premair Series delivers industry-leading thrust forces in a compact, low-profile package, making it the definitive solution for space-constrained pneumatic systems.

Which Premair Series is Right for Your Project?

Premair Square Metric (12mm – 100mm)

The Precision Specialist.

If your application requires side-by-side mounting or precision position sensing, the Square Metric series is your best fit.

Mounting Ease: Threaded through-holes allow for direct mounting without extra brackets.

Smart Sensing: Magnetic pistons come standard, allowing for easy integration of "Auto Switches" for automation feedback.

Space Savings: Features a low-profile aluminum body that minimizes weight on moving machine parts.

Premair Round Compact (1-1/8” – 4”)

The Rugged Workhorse.

Designed for high-pressure environments (up to 250 PSI), the Round series uses a heavy-duty tie-bolt construction to handle rigorous industrial cycles.

Superior Bushings: Uses Duralon® non-metallic bushings which offer a lower coefficient of friction and significantly higher load-bearing capacity than standard bronze bearings.

Impact Resistance: Thick aluminum alloy covers and heavy-walled barrels prevent damage from external impacts.

Standard Inch Mounting: Designed to interchange seamlessly with existing industrial compact cylinders.

Key Technical Benefits

"Self-Lubricating Efficiency"

Every Premair cylinder is factory-treated with Magnalube®-G or features self-lubricating internal surfaces. This means you can run these cylinders in non-lubricated air systems without worrying about premature seal failure.

Piston Rod Quality: We use hard chrome-plated stainless steel as a standard, not an upgrade. This ensures your rods won't pit or rust, even in humid or wash-down environments.

Customizable Ends: Choose between Female NPT Rod Threads (Standard) or Male thread options to fit your specific tooling requirements.

Extended Seal Life: The precision-machined grooves and captive rod seals prevent "seal roll" and ensure airtight performance for millions of cycles.

Typical Services & Ideal Applications

Typical Applications

Material Handling: Clamping, sorting, and diverting on conveyors.

OEM Machinery: Compact assembly fixtures and gate actuation.

Robotics: End-of-arm tooling and precise positioning.

Packaging: Ejection pins, flap folders, and labeling stations.

Comparison Matrix: Premair Square vs. Round

Premair Square (Metric)

The Premair Square is designed for precision and compact integration.

Primary Advantage: Features built-in sensing capabilities and versatile side-mounting options.

Performance: Operates at a maximum of 140 PSI.

Temperature: Designed for standard factory temperature ranges.

Build: Constructed with a high-quality chrome plated stainless steel rod.

Mounting: Utilizes threaded thru-holes for secure installation.

Premair Round (Inch)

The Premair Round is the heavy-duty choice for more demanding industrial environments.

Primary Advantage: Engineered specifically to handle high pressure and heavy-duty loads.

Performance: Offers a higher maximum operating pressure of 250 PSI.

Temperature: Highly adaptable with high-temperature options available for extreme conditions.

Build: Features a durable chrome plated stainless steel rod.

Mounting: Designed for tie-bolt or spacer mounting configurations.
