Airtac MARF Stainless Steel Mini Air Cylinder MARF32X230S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF32X230S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø32mm bore and 230mm 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 MARF32X230S
A 230 mm stroke puts the 32 mm MAR barrel to work over a long reach, holding 402.2 N of push at 0.5 MPa (563.0 N at 0.7 MPa). The round body is a riveted stainless-steel barrel with a hard-chrome plated rod, so damp corners, coolant mist and occasional washdown do not chew it up the way painted mini cylinders suffer. Adjustable air cushions at both stroke ends let you dial out arrival shock and run faster cycles without hammering the aluminium covers.
The F front flange is built into the front cover, so the cylinder bolts straight to a machine plate - no separate foot bracket to buy. For real-world sizing, plan on roughly 241 N of usable push at 0.5 MPa instead of the full rating, which is about a 20 kg vertical lift with a 2:1 margin kept. A magnet ships as standard, so CMSG, DMSG or EMSG switches clip on the barrel for end-of-stroke signals.

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 MARF32X230S Is Used
Carton pusher on a sortation lane
Sweeps shipping cartons off a conveyor into a staging chute, using the 230 mm reach to clear a wide lane.
Sack ejector on a bagging line
Kicks filled flour sacks off the bagger table once the weigher signals stroke end via a CMSG switch.
Case diverter at a warehouse splitter
Swings divider gates to route 10 kg cases down one of two chutes at 0.5 MPa working pressure.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF32X230S the Right Cylinder?
If 402 N at 0.5 MPa overshoots the job, the 25 mm MAR gives about 245 N at the same pressure; when cycles need more muscle, step up to the 40 mm bore for 628 N. This is a plain double-acting cylinder - with air off the rod drifts, so add a rod lock if position must survive an air drop.
At 230 mm of extension, guide the tooling or keep side forces low to protect the 12 mm rod from bending, and trim the cushion needles on first run. The 1/8 inch port suits this 32 mm bore; add a G or T suffix if your plant runs BSPP or NPT fittings.
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 MARF32X230S FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N; at 0.7 MPa output rises to 563.0 N push and 483.8 N pull. The theoretical ceiling for this 32 mm bore is 82 kgf at 1.0 MPa.
Variable air cushion sits at both ends - turn the needle screws in slightly to soften arrival, useful near the 800 mm/s top speed. The cylinder runs on filtered air at 0.15-1.0 MPa (22-145 psi) with 40 um filtration and a 1.5 MPa (215 psi) proof rating.
