Airtac MARF Stainless Steel Mini Air Cylinder MARF32X200S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X200S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 MARF32X200S
The MARF32X200S is AirTAC's round-body 32 mm mini cylinder with a 200 mm stroke and a front flange built into the front cover, so the cylinder bolts straight to a machine plate without a separate mounting bracket. It is double acting with a variable air cushion at both ends, and at 0.5 MPa it pushes 402 N and pulls 346 N, rising to 563 N at 0.7 MPa. In practice that leaves about 241 N of usable pushing force at 0.5 MPa when you keep a sensible reserve, roughly a 24 kg part moved horizontally with margin.
The barrel is stainless steel rolled onto aluminium covers with a hard-chrome plated 12 mm rod, a combination that shrugs off washdown and damp shop air far better than painted mini cylinders. Air cushions at each end are tuned with the needle screws on first run, letting the 200 mm stroke end softly even at higher speeds. The built-in magnet is standard, so CMSG, DMSG or EMSG switches clip on for end-of-stroke sensing. Operating window is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MARF32X200S Is Used
Bottling line gate
Swings a diverter gate across a 200 mm bottle lane; the front flange bolts the cylinder flat to the conveyor frame and the cushion keeps the gate from slamming at each index.
Weld fixture clamp
Clamps brackets on a robotic weld table with about 241 N of usable force at 0.5 MPa, plenty for holding thin-gauge parts through the tack weld.
Carton ejector
Pushes filled cartons off the end of a packing conveyor; 402 N at 0.5 MPa clears light stacks without moving up to a bigger bore.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X200S the Right Cylinder?
At 402 N push at 0.5 MPa, the 32 mm bore sits mid-range: drop to a 25 mm MAR (245 N push) for lighter fixtures or step up to 40 mm (628 N) when loads grow. If the workpiece must stay put when air is lost, add a rod lock - a standard MAR will drift, since the cushion only softens the stroke end. Match the port to your air line: 1/8" on this bore, with an M10x1.25 male rod thread for I or Y knuckles and tooling.
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 MARF32X200S FAQ
Feed it 0.5 MPa and you get 402 N on extension and 346 N on retraction; step to 0.7 MPa for 563 N push and 484 N pull. The theoretical ceiling at 1.0 MPa is 82 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The F in the code means the flange is built into the front cover, so you bolt the cylinder straight to a plate - no separate foot or bracket to source. The 12 mm hard-chrome rod carries an M10x1.25 male thread, and I or Y knuckles fit it directly.
