Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 225mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S
Need just over 200 mm of travel from a compact cylinder? The MARF32X225S runs a 32 mm bore over a 225 mm stroke, pushing 402 N and pulling 346 N at 0.5 MPa - call it 241 N of usable push once you leave a reserve - and 563 N at 0.7 MPa. Its front flange is integrated into the cover, so mounting is a single bolted joint with no loose bracket to align.
The riveted stainless barrel and hard-chromed 12 mm rod handle damp, washdown-prone areas without flaking paint or pitting, a real edge over coated mini cylinders in food and outdoor machinery. Dual variable air cushions dial out end-of-stroke shock, and with the magnet fitted as standard, CMSG / DMSG / EMSG switches read position straight from the barrel. Air supply: 0.15-1.0 MPa (22-145 psi); speed range 30-800 mm/s.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S Is Used
Inspection camera lift
Lifts a vision camera head of about 20 kg vertically over 225 mm - half the 41 kgf the bore can raise at 0.5 MPa, keeping a 2:1 margin.
Case pusher infeed
Squares and pushes corrugated cases into a case packer infeed; the integrated front flange aligns the push face with the case rail in one fixing.
Parcel lane diverter
Deflects small parcels between lanes on an e-commerce sorter, with the variable cushions absorbing the stop at every divert cycle.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S the Right Cylinder?
Where does 32 mm sit? The 25 mm MAR manages 245 N at 0.5 MPa and the 40 mm manages 628 N, so choose this bore when a 225 mm move needs about 400 N. Keep roughly 60 percent of the rating for real work and let the cushions absorb the stop. Because the F flange is built in, you get one bolted interface and no extra bracket; a 1/8" port feeds each end and the M10x1.25 rod thread takes I or Y knuckles.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MARF Stainless Steel Mini Air Cylinder MARF32X225S FAQ
At 0.5 MPa the bore yields 402 N forward and 346 N back; 0.7 MPa raises that to 563 N and 484 N. At the 1.0 MPa theoretical maximum the figure is 82 kgf. Run between 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Yes. Both ends carry a variable cushion; turn the needle screws in or out on first run until the 225 mm stroke ends smoothly. Correctly set cushions let you run toward 800 mm/s or move heavier loads without hammering the covers. The cushion softens the stop only - it does not lock the rod.
