Airtac MARF Stainless Steel Mini Air Cylinder MARF32X260S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X260S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 260mm 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 MARF32X260S
Long reach with steady muscle: over its 260 mm stroke this 32 mm MAR keeps 402.2 N of push available at 0.5 MPa, rising to 563.0 N at 0.7 MPa. The stainless round barrel, rolled onto the aluminium covers with a stainless block, tolerates damp plant air and occasional washdown that would pit ordinary mini cylinders. Cushion needles at each end soften arrival, which matters once a long rod carries real momentum.
The F front flange is integral to the cover, so no separate mounting bracket clutters the machine layout. Plan on about 241 N of working force at 0.5 MPa for actual moves; vertically that is near a 20 kg lift once a 2:1 margin is applied. Sensor-ready out of the box, the standard piston magnet pairs with CMSG, DMSG and EMSG switches for stroke-end detection.

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 MARF32X260S Is Used
Parcel sweep on a courier sorter
Sweeps parcels from a sorter belt into a destination chute, cushioned ends protecting the frame at high cycle rates.
Tray pusher on a thermoformer
Pushes formed food trays off the forming station into stacking magazines on every machine cycle.
Gate driver on a sand hopper
Rods a slide gate open on a foundry sand hopper, the chrome-plated rod resisting abrasive dust wear.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X260S the Right Cylinder?
When the move needs more than 402 N at 0.5 MPa, the 40 mm MAR reaches 628 N; for lighter, quicker strokes the 25 mm bore at 245 N saves air. Holding is not built in - on air loss the rod drifts freely, so pair the cylinder with a rod lock where the load must stay put. Speeds of 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air cover most transfer duty.
With 260 mm of unsupported travel, keep side loads small and guide tooling externally to spare the 12 mm rod. Thread is PT as standard; specify G or T for BSPP or NPT plants, and fit I or Y knuckles to the M10x1.25 rod for pivoting linkages.
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 MARF32X260S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push is 563.0 N and pull 483.8 N. The 32 mm bore reaches 82 kgf of theoretical force at 1.0 MPa.
The stainless-steel barrel and 20 um hard-chromed rod resist corrosion far better than painted-steel minis, and the riveted round body keeps a tight, permanent seal. Run it on 40 um filtered air at 0.15-1.0 MPa (22-145 psi); proof pressure is 1.5 MPa (215 psi).
