Why Use Air Over Oil Cylinders?

 air over oilAir over oil cylinders are pneumatic cylinders designed to produce greater force than standard pneumatic cylinders of the same bore size. They incorporate both oil and air within the mechanism, creating a hybrid pneumatic-hydraulic cylinder that intensifies the amount of force generated by compressed air input.

HyperCyl takes the innovative design of hybrid air over oil cylinders to the next level with our patented rod and piston mechanism. Unlike other designs, our cylinders do not use an external oil reservoir. Instead, the oil reservoir is completely sealed and incorporated into the cylinder itself. Our air over oil cylinders uses compressed air on the piston to exert force within a sealed hydraulic chamber by pneumatically driving a rod into the oil reservoir, which is situated behind the work piston. 

Why Use Air Over Oil Cylinders?

Air over oil cylinders offer a host of unique advantages over more traditional pneumatic systems. Since compressed air is ubiquitous in virtually every industrial setting, it offers a convenient source of clean power that can easily be intensified using HyperCyl’s air over oil cylinders.

Our state-of-the-art air over oil cylinder design offers a low-cost, highly efficient means of converting compressed air to smooth fluid force. HyperCyl’s air over oil cylinders only use 25% – 30% of compressed air when compared with multi-piston pneumatic cylinders for the same operation. 

While many companies are phasing out hydraulic power units and cylinders, the HyperCyl air over oil cylinders offer a cost-effective solution for facilities that want the power of a hydraulic system in a smaller package. Our air over oil intensifier units can provide up to 200 tons of force while using significantly less space than traditional hydraulic systems. The smaller size of our air over oil cylinders allows for reduced bore size compared to standard multi-stage pneumatic cylinders. 

Our air over oil cylinders make no more sound than a standard pneumatic cylinder. Since there is no power unit like hydraulics, you enjoy less noise, less heat generation, and no continuously running motor. Energy is needed only while HyperCyl is moving; at rest zero noise and zero energy is realized. To suit your specific needs, we offer six models of air over oil intensifier cylinders suitable for a broad variety of industries and applications. In addition, we are pleased to work with you to create custom stroke cylinders quickly and efficiently, within your budget. 

Partnering With HyperCyl for Air Over Oil Cylinders

For more than 25 years, HyperCyl has been a leading expert in the design and manufacture of air over oil, or hydra-pneumatic, cylinders. Our extensive expertise extends to servo-controlled actuators, assembly cells, and presses using our cutting-edge cylinder technology. As a privately-owned company based out of Dundee, Michigan, we are proud to produce our products in America. 

We are dedicated to helping our customers find the perfect motion solutions for their particular needs. Our seasoned experts will work closely with you to determine the appropriate force and stroke requirements for optimal power and efficiency. Each of our air-over-oil cylinders offers unique features to enhance your operations, soft initial part contact and enhanced energy efficiency. The pressure stroke of the cylinder can be regulated separately from the approach stroke, allowing you to fully tailor your force and energy usage for optimal cost savings.  

At HyperCyl, we offer a variety of triggering mechanisms for high-pressure actuation, without the need for cylinder alterations. This mechanism can be triggered based on a pressure threshold (ELT sensor), specified stroke distance (LVDT), or a simple proximity sensor. Other standard features of our air over oil cylinders include:

  • Complete air/oil separation
  • Wear bands on internal pistons for increased life
  • Variable operating positions or attitudes
  • No external oil reservoir
  • Up to 200 tons linear output force
  • Three primary moving components
  • NFPA medium-duty mounting
  • Tie rods with 100,000 psi tensile-strength 
  • Operation and maintenance manual
  • Heavy-duty construction for long service life
  • 4.5 million MTBF (mean time before failure)
  • 20 million cycle service life
  • Accessories include gauge kits, sensors, total stroke limiters, alignment couplers, rod locks, and more
  • HyperCyl’s “IntelliCyl” package offers in-process validation of each part thereby dramatically reducing part-nonconformance, scrap rates, and check QTY of fixtures involved
  • Limited Lifetime warranty for cylinder materials and workmanship
