Airtac MARF Stainless Steel Mini Air Cylinder MARF25X230S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X230S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm bore and 230mm 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 MARF25X230S
The 230 mm stroke version of the MAR front-flange mini series is a round-bodied 25 mm bore actuator: double acting, variable air cushion at both ends, with the mounting flange riveted right into the front cover. It pushes 245 N and pulls 206 N at 0.5 MPa, reaching 343 N of push on a 0.7 MPa supply across a 0.15-1.0 MPa (22-145 psi) working band.
The stainless barrel and hard-chrome plated rod resist washdown and humid air far better than painted mini cylinders, which makes this bore a fit for damp food and outdoor spots. Plan continuous work around 147 N of the 245 N rating - roughly a 12 kg vertical lift with margin - and the built-in piston magnet, standard rather than an option, accepts CMSG, DMSG or EMSG switches straight away.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MARF25X230S Is Used
Canning line reject gate
Runs the reject pusher that tips off-spec cans over 230 mm of travel; the flanged body bolts flat to the conveyor side plate and the 245 N push at 0.5 MPa clears a full can lane with room to spare.
CNC enclosure guard slide
Slides the polycarbonate guard door across a compact machining enclosure; adjust the cushion needles at each end so the door settles quietly instead of hammering the front cover.
Tray transfer pusher
Pushes plastic trays sideways between conveyor lanes in a bakery packing area; the stainless barrel and chrome rod shrug off flour dust and routine hose-down.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X230S the Right Cylinder?
A 25 mm bore gives 245 N push at 0.5 MPa - sitting between the 20 mm MAR (157 N) and the 32 mm MAR (402 N), so drop down for lighter gates or step up when duty runs hot. The 230 mm stroke sits well inside the 500 mm standard limit for this bore, but a 10 mm rod that long will bend under side load, so guide the load externally. The flange is integral, so no FA or LB bracket applies, and on air loss the rod simply drifts - fit a rod lock if position must be held.
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 MARF25X230S FAQ
At 0.5 MPa the 25 mm bore pushes 245.3 N and pulls 206.1 N in this double-acting design; at 0.7 MPa push rises to 343.4 N. The theoretical maximum is 50 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and rod speed runs 30-800 mm/s.
No - every MAR cylinder ships with the magnet built into the piston as standard. Snap a CMSG, DMSG or EMSG reed or electronic switch onto the stainless barrel and it reads position immediately; nothing to special-order or retrofit.
