Airtac MARF Stainless Steel Mini Air Cylinder MARF50X175S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X175S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 175mm stroke, 1/4" 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 MARF50X175S
A 50 mm bore, 175 mm stroke mini cylinder in AirTAC's MA round-body format: the aluminium covers and stainless block are rolled onto the stainless-steel tube, giving a sealed, washdown-friendly shell that shrugs off the damp and mild chemicals that ruin painted-steel minis. Double acting throughout, with a variable cushion at each end you adjust on first run.
Extend force at 0.5 MPa is 981.3 N (1373.8 N at 0.7 MPa), enough to push, clamp or lift serious loads at 30-800 mm/s. Sized for work, expect around 589 N of usable push at 0.5 MPa; that is roughly a 50 kg vertical lift at half the theoretical 100 kg, leaving a 2:1 margin. The magnet is fitted as standard, so sensor feedback via CMSG, DMSG or EMSG needs no special piston.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MARF50X175S Is Used
Press die part ejection
Kicks stamped or moulded parts out of a die with 981 N at 0.5 MPa; the 175 mm stroke reaches deep into the die area.
Pallet divert on sortation lines
Pushes totes between conveyor lanes; the integrated front flange mounts directly to the sorter frame without extra brackets.
Wet-plant rod actuation
Suited to wastewater skids and outdoor gates, where the riveted stainless shell outlasts painted or bare aluminium bodies.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X175S the Right Cylinder?
At 0.5 MPa the neighbouring bores give 628.3 N (40 mm) and 1557.9 N (63 mm); this 50 mm barrel delivers 981.3 N, a good fit when 40 mm feels marginal but 63 mm is oversized. Usable force after a sensible margin is about 589 N at 0.5 MPa. The integrated front flange replaces a separate mounting accessory - bolt the cover face to the machine and the F mount takes the thrust directly. If the load must stay put on air loss, remember a standard MAR drifts; pair it with a rod lock. The 175 mm travel sits well inside the 500 mm standard range, and CMSG / DMSG / EMSG switches read position from the built-in magnet.
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 MARF50X175S FAQ
Extend: 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa. Retract: 880.8 N at 0.5 MPa and 1233.1 N at 0.7 MPa. Theoretical maximum at 1.0 MPa is 200.1 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
No. Every MA-series cylinder, including the MARF50X175S, ships with the magnet built in as standard. CMSG, DMSG and EMSG switches clamp directly onto the stainless barrel and read end-of-stroke or mid-stroke position without any special-order option.
