Airtac MARF Stainless Steel Mini Air Cylinder MARF25X360S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X360S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm bore and 360mm 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 MARF25X360S
Deep fixtures and sliding guards are easy work for MARF25X360S, which spans 360 mm on the compact 25 mm MAR body and carries its own integrated front flange. It is double acting at 30-800 mm/s, with a variable air cushion at each end that you set with the needle screws during commissioning.
The 25 mm bore generates 245 N push at 0.5 MPa; plan on roughly 147 N of that for real work after de-rating. Its riveted stainless barrel shrugs off mild corrosion in food, outdoor and coolant-splashed spots, and the standard-fit magnet means a CMSG, DMSG or EMSG switch clips on whenever end-position sensing is added.

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 MARF25X360S Is Used
Deep-reach ejector plate
Pushes cured rubber parts from a tool face set 360 mm inside the press frame; the 245 N push at 0.5 MPa clears light, sticky parts.
Guard door slider
Slides a machine guard panel 360 mm open; the stainless barrel and chrome rod tolerate washdown around wet or dusty enclosures.
AGV battery bay cover
Opens the sliding cover of an AGV battery bay with about 12 kg of vertical-lift capability behind it, using EMSG-switched end positions for feedback.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X360S the Right Cylinder?
Between bores: 20 mm MAR cylinders push 157 N at 0.5 MPa, 25 mm push 245 N and 32 mm reach 402 N - pick by load, not by price. At 360 mm the slender 10 mm rod is exposed for most of its length, so mount the load on its own linear guide and align the flange true to avoid rod binding. Like every standard MAR, this one does not hold stroke on air loss; only a rod lock gives a failsafe hold, while the cushion screws just soften the ends. The magnet arrives installed, so retrofitting an EMSG switch later needs no cylinder change.
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 MARF25X360S FAQ
Push is 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa; pull is 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa. Maximum theoretical force is 50 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating.
No. It is a plain double-acting cylinder, so the piston drifts on air loss; the variable cushion only softens the stroke ends. For a failsafe hold on a 360 mm travel, pair it with a rod lock. If you only need position signals, the standard magnet already supports CMSG, DMSG and EMSG switches.
