Airtac MARF Stainless Steel Mini Air Cylinder MARF25X30S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X30S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MARF25X30S
Tight machine faces and short clamps suit MARF25X30S: a 25 mm round-body mini with just 30 mm of travel, double acting and fitted with variable air cushions at both stroke ends. Its front flange is an integral part of the rolled front cover, so the cylinder meets the mounting face directly with nothing extra to bolt behind it.
Rated 245 N push at 0.5 MPa, a realistic planning figure is about 147 N of usable work at that pressure once you de-rate for load factor. A hard-chrome 10 mm rod running in a stainless barrel handles splashing coolant and humid plant air far better than painted minis, and the standard magnet drops straight into position reporting with CMSG or DMSG switches.

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 MARF25X30S Is Used
CNC jig fixture clamp
Clamps an aluminium workpiece with a 30 mm squeeze; about 147 N of usable push at 0.5 MPa is ample for a hold-down of this class.
Flap tucker on a box line
Tucks the end flap of small cartons at speed - the short 30 mm stroke suits cycle rates up to 800 mm/s.
Part-present flag actuator
Kicks a proximity flag in a bottling filler; the built-in magnet drives a CMSG switch so the PLC knows the flag moved.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X30S the Right Cylinder?
Compare across the family: at 0.5 MPa the 20 mm bore pushes 157 N and the 32 mm bore 402 N, so the 25 mm bore at 245 N sits mid-range for clamping duty. A 30 mm stroke keeps the 10 mm rod stubby and largely immune to bending, but heavy overhang loads should still ride on a guide. There is no position holding when air is cut - the piston coasts freely and the variable cushion only damps the final millimetres - so specify a rod lock if the clamp must stay closed on failure. Mounting is by the integral front flange, so nothing extra is ordered.
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 MARF25X30S FAQ
The 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa, and 343.4 N push with 288.5 N pull at 0.7 MPa; theoretical maximum is 50 kgf at 1.0 MPa. Air ports are 1/8 in, the rod thread is M10x1.25, and operating pressure runs 0.15-1.0 MPa (22-145 psi).
Yes - the variable air cushion at both ends is adjustable with the needle screws on first run, so even a fast 30 mm hit at up to 800 mm/s will not hammer the aluminium covers.
