Airtac MARF Stainless Steel Mini Air Cylinder MARF32X250S
The AirTAC MARF Stainless Steel Mini Air Cylinder MARF32X250S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MARF32X250S
With 250 mm of travel, this 32 mm MAR mini cylinder keeps 402.2 N of push on tap at 0.5 MPa across the whole stroke. Its stainless round barrel is rolled tight against aluminium-alloy covers, and the 20 um hard-chrome rod resists rust and scoring in humid or lightly washed areas. Twin adjustable cushions at the stroke ends absorb deceleration, so carriers can run near the top of the 30-800 mm/s speed band without banging the covers.
Because the F front flange is part of the cover casting, mounting is a simple four-bolt job with no add-on bracket. The piston magnet is standard equipment, so a CMSG or DMSG switch snaps on for position feedback.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X250S the Right Cylinder?
Downsize to the 25 mm MAR if 245 N at 0.5 MPa covers the load; move to 40 mm (628 N push at 0.5 MPa) when the application demands more headroom. On air loss the rod free-drifts - only a separate rod lock holds position, not the cushions. Operating window is 0.15-1.0 MPa (22-145 psi) with 40 um filtered air.
A 250 mm extension magnifies any side load, so align tooling square and use external guides for off-center parts. Ports are 1/8 inch on all 32 mm bores; add a G or T suffix for BSPP or NPT threads, and match I or Y knuckles to the M10x1.25 rod for pivoting links.
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 MARF32X250S FAQ
Push at 0.5 MPa is 402.2 N and pull is 345.6 N; at 0.7 MPa push reaches 563.0 N and pull 483.8 N. The 32 mm bore tops out at 82 kgf theoretical force at 1.0 MPa.
No. The magnet is built in as standard on every MA-series cylinder, so CMSG, DMSG and EMSG switches mount directly on the 32 mm stainless barrel for stroke-end or mid-stroke detection without a special order.
