Airtac MARF Stainless Steel Mini Air Cylinder MARF25X260S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X260S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm bore and 260mm 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 MARF25X260S
With 260 mm of rod travel, the MARF25X260S covers long pushes from a compact 25 mm bore: 245 N of thrust at 0.5 MPa, 206 N on retract, double acting with variable air cushions at each end of the stroke.
AirTAC builds it as a rolled stainless tube with aluminium covers and a chrome-plated rod, so damp or dusty plants wear painted minis out long before this one.

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 MARF25X260S Is Used
Palletizer infeed pusher
Pushes layers of sacked goods onto the palletizer infeed conveyor; the 260 mm stroke crosses two roller pitches and the flange bolts straight onto the machine frame.
Washdown gate lifter
Lifts a diverter gate on a seafood processing line, where frequent hose-down rules out painted steel and the stainless barrel with chrome rod keeps moving.
Back-gauge tooling slide
Positions a stop slide on a small press-brake back gauge; the built-in magnet with an EMSG switch signals each of the preset positions along the 260 mm travel.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X260S the Right Cylinder?
The 25 mm bore sits at 245 N push and 206 N pull at 0.5 MPa; the 20 mm MAR offers 157 N and the 32 mm MAR 402 N if your load calls for it. Stroke 260 mm remains a standard length (catalogue maximum is 500 mm for this bore), but over that span carry side loads on external guides to avoid bending the 10 mm rod. The front flange is integral to the cylinder so no separate foot or flange kit applies, and because nothing holds the rod on air loss, add a rod lock wherever a stopped position must be kept.
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 MARF25X260S FAQ
At 0.5 MPa the 25 mm bore gives 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull. Theoretical maximum is 50 kgf at 1.0 MPa. Run the cylinder on 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), with air filtered to 40 um, at 30-800 mm/s.
No. The F code means a front flange is built into the front cover and riveted with the body, so the cylinder bolts flush to your machine plate. Separate foot or flange kits are not offered for MAR - only I or Y rod knuckles attach to the 10 mm rod as extras.
