Airtac MARF Stainless Steel Mini Air Cylinder MARF32X300S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X300S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MARF32X300S
Front-mounted and cushioned both ends, the MARF32X300S is a double-acting round-body mini cylinder whose 32 mm bore pushes 402 N at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) supply range. The front flange is rolled into the front cover itself, so there is no separate mounting bracket to order or align.
Its riveted stainless-steel barrel and hard-chrome plated 12 mm rod shrug off damp and mild washdown that rust painted minis, and a piston magnet comes standard for CMSG, DMSG or EMSG switches. Size the job around about 241 N of usable force at 0.5 MPa and this 300 mm stroke version covers long gates, pushers and ejectors without hammering its covers - the variable cushion takes care of that.

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 MARF32X300S Is Used
Bottling line gate lift
Raises a bottle-guide gate through 300 mm between filler lanes; 402 N at 0.5 MPa lifts the gate briskly while the cushion lands it quietly.
Carton pusher
Ejects cartons sideways off a packaging conveyor; the front flange bolts directly to the conveyor frame with no extra bracket.
Die part ejection
Kicks stamped or formed parts clear of the die after forming; the stainless barrel stands up to coolant mist around the press.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X300S the Right Cylinder?
One bore down, the 25 mm MAR delivers 245 N at 0.5 MPa; one bore up, the 40 mm MAR reaches 628 N, so pick 32 mm when the load sits between. Over a 300 mm stroke, keep the 12 mm rod free of side load or add external guides, since long strokes amplify rod bending. Related types worth a look: MAC if you prefer a cylinder with a separate flange or foot, MACJ when the stroke itself must be adjustable. If the application must hold position with air off, note that this cylinder drifts - fit a rod lock. I and Y rod knuckles thread onto the M10x1.25 rod end.
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 MARF32X300S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N. At 0.7 MPa the figures rise to 563 N push and 484 N pull, and the theoretical maximum is 82 kgf at 1.0 MPa. Ports are 1/8 inch and the 12 mm rod threads M10x1.25.
Adjustable needle screws sit in both covers: open them fully before first run, then trim in until the 300 mm stroke ends land without knock. The built-in magnet is standard, so CMSG, DMSG or EMSG reed or electronic switches mount straight onto the barrel.
