Airtac MARF Stainless Steel Mini Air Cylinder MARF32X140S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X140S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 140mm 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 MARF32X140S
Front mounting is engineered into the MARF32X140S itself - the flange face is rolled up with the aluminium cover - so the 32 mm bore, 140 mm stroke cylinder locates on your machine with one bolt pattern and zero accessory orders. Extend force at 0.5 MPa is 402 N, an honest working budget of around 241 N after reserving headroom.
Speed can run the full 30-800 mm/s because variable air cushions at both ends absorb the stop, tuned by turning the needle screws until the 140 mm travel lands softly. Supply is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and the factory magnet makes CMSG, DMSG or EMSG position switches a clip-on affair.

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.

Where the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X140S Is Used
Camera lift on a vision station
Lifting an inspection camera clear of the part between cycles on a PCB line; the 140 mm stroke clears tall fixtures and the flange mounts the cylinder under the camera bridge.
Glue head on a case erector
Dipping a glue head onto blank carton flaps; 402 N of extend force presses the head home and the cushioned stop protects the nozzle.
Burn-in rack actuator
Connecting and disconnecting test probes on electronics in a burn-in rack, where the stainless barrel and chrome rod shrug off the warm, slightly humid rack environment.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X140S the Right Cylinder?
Neighbour sizes for scale: 25 mm bore manages 245 N at 0.5 MPa while 40 mm bore manages 628 N, so step down for light gates or up for heavy clamps. This is a straightforward double-acting cylinder, not a holder - on air loss the piston slides with whatever the load does, which is when a rod lock belongs in the circuit. Match the CMSG / DMSG / EMSG switch of your choice to the standard magnet and the sensing loop is complete.
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 MARF32X140S FAQ
Yes: 402 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, and a theoretical 82 kgf maximum at 1.0 MPa. The 32 mm bore uses a 12 mm rod with M10x1.25 thread and a 1/8" port; 140 mm is well within the 500 mm standard stroke limit.
No - every MA-series cylinder, this one included, ships with the piston magnet as standard equipment. That means a CMSG, DMSG or EMSG switch snaps onto the stainless barrel for end-of-stroke signalling without ordering a special piston or waiting on a custom build.
