Airtac MARF Stainless Steel Mini Air Cylinder MARF32X40S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X40S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MARF32X40S
Short stroke, big utility: the MARF32X40S is a Dia 32 round-body mini cylinder that pushes 402 N and pulls 346 N at 0.5 MPa, with its own front flange rolled into the front cover. There is no separate bracket to order - the body bolts flat to the machine face, and a variable air cushion at each end lets you tune away end-of-stroke bang.
The piston magnet comes fitted as standard, so CMSG, DMSG or EMSG switches drop straight on with no piston changes. The stainless barrel and hard-chromed rod also shrug off splash and washdown mist that swells painted minis. For sizing, count on roughly 241 N of real working force at 0.5 MPa, which lifts about 20.5 kg vertically with a 2:1 margin.

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 MARF32X40S Is Used
Carton push-off on a case packer
The 40 mm stroke clears a finished case off the infeed belt in one hit, while 402 N at 0.5 MPa handles packed weight without stalling.
Clamp on a drill jig
Front-flange mounting bolts the body flat to the jig plate; about 241 N of usable clamp force holds small steel parts through drilling.
Sorter gate kicker
Air on both ports drives the gate across the lane, and cushions at each end let cartons be deflected cleanly at high cycle speeds.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X40S the Right Cylinder?
Below this size, a Dia 25 MAR manages 245 N push at 0.5 MPa; above it, a Dia 40 unit reaches 628 N - so stay at Dia 32 when the load sits between roughly 150 and 240 N after your safety margin. A plain MAR will drift if air pressure is lost, since nothing mechanically locks the rod; fit a rod lock where a load must stay parked. The 1/8" port and M10x1.25 male rod thread accept standard fittings and I or Y rod knuckles.
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 MARF32X40S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa, 563 N push and 484 N pull; the theoretical maximum is 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, strokes at 30-800 mm/s, and the cushion at both ends is adjustable.
No. Every MA-series barrel carries the magnet as standard, so CMSG, DMSG or EMSG switches mount directly on the stainless tube without any piston modification.
