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.
