Airtac MARF Stainless Steel Mini Air Cylinder MARF25X130S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X130S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm bore and 130mm 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 MARF25X130S
Front-mounted and cushioned at both ends, the MARF25X130S is AirTAC's double-acting round mini cylinder in the 25 mm class: 245.3 N push and 206.1 N pull at 0.5 MPa (about 72 psi), delivered through a 10 mm hard-chrome plated rod.
Its aluminium covers and stainless block are rolled onto the stainless barrel, a riveted construction that keeps the joint sealed through damp or lightly washed-down conditions where painted minis blister. In practical terms the same 0.5 MPa supply supports roughly 147 N of working force, or a vertical lift of about 12 kg with a 2:1 safety factor. The piston magnet ships standard, so CMSG, DMSG and EMSG switches attach without special ordering.

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 MARF25X130S Is Used
Dough-tray ejector
Pushing stacked bakery trays off a rack guide is a 206 N retract job here; the 130 mm stroke matches a standard tray pitch so trays clear fully each cycle.
PCB test fixture clamp
Clamping a 250 x 180 mm board into a bed-of-nails fixture takes roughly 147 N of controlled force, with the cushion preventing contact bounce.
Spray-gun traverse slide
Reciprocating a spray gun across a 130 mm window in a paint booth suits the 30-800 mm/s speed band, and booth humidity favors the stainless barrel.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X130S the Right Cylinder?
The smaller MAR 20 bore gives 157.0 N of push at 0.5 MPa, while 32 mm reaches 402.2 N for heavier jobs. If the fixture must hold a part when air drops, this cylinder will not: the piston drifts, and its cushion only eases the final millimetres, so fit a rod lock where holding matters. The flange is already on the front cover, so there is no foot bracket to order, position feedback rides on the standard piston magnet, and the 1/8 inch ports take an M10x1.25 male rod thread.
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 MARF25X130S FAQ
Extend force is 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa; retract is 206.1 N and 288.5 N at the same two pressures. Maximum theoretical output is 50 kgf at 1.0 MPa. Supply air filtered to 40 um between 0.15-1.0 MPa (22-145 psi); proof pressure 1.5 MPa (215 psi).
Better than most minis its size. The barrel is stainless steel, the rod is carbon steel hard-chrome plated to 20 um, and the covers are rolled on rather than tied, leaving no loose tie rods to corrode or work loose. It is not a sealed IP67 unit, so avoid direct jetting, but humid rooms, splashes and regular wipe-downs are well within its comfort zone.
