will a hydraulic cylinder work with compressed air? how many psi is required to match hydraulic pressure?

A hydraulic cylinder will work with pneumatic power. There might be a loss of power factor due depending in the seals used inside.
Hydraulic power is better for several reasons:
More stable movement-due to the reduced amount of compression of oil. Air inside the cylinder will compress more and oil less. For heavy loads this is an important fact.
Higher power ratings in a smaller design. 3,000 to 10,000 psi is common in hydraulic systems. To obtain that in pneumatics would require lots of expensive equipment, if you could obtain it at all.

Hydraulic cylinders are easy to find, cheap as chips, many different sizes and configurations, rated to 3,000 psi usually. Air cylinders are a lot harder to find, a lot more expensive

An air cylinder uses strictly air.
A hydraulic cylinder uses fluid or a combination called air over oil.
A hydraulic cylinder cannot function properly with just air.
An air system cannot match hydraulic pressure. Even if you could get a cylinder big enough the air system compresses too much. An oil system does not compress so there will always be a greater force.

From a master mechanic technician ( A ) is totally wrong There is no caliper assembly on any drum No caliper assembly holds any wheel cylinder A caliper assembly is a self contained unit, that uses hydraulic pressure applied to the brake pad,then to the rotor to stop a vehicle. Air in a hydraulic brake system will only create a no stop situation, resulting in a crash, this is why we BLEED the system. Hydrualic brake fluid is used in all modern vehicles today period.

yes it will work but no it will not last with air. As the seal are made to be use with oil.
Psi of air is the same as psi of oil. Now hydraulic pumps can put out 3,000 psi easy.

Generally not a good idea.
Pressure, (air), would be equal to pressure, (liquid), for force delivered, however air would not be optimal for positioning. (Would act like a spring rather than a solid hold.)
Different type seals would be required.

it's self explanatory. air and fluid. fluid withstand more pressure and has less restrictions with altitute.

hydro = liquid
air= air
thy HC will handle lots more pressure.
