Airtac MARF Stainless Steel Mini Air Cylinder MARF50X160S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X160S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 160mm 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 MARF50X160S
Built around a riveted stainless round barrel, the MARF50X160S is a double-acting mini cylinder with a front flange (F mount) formed into the front cover itself - no separate flange or foot bracket to buy. A variable air cushion sits at both ends, so end-of-stroke shock can be tuned out with the needle screws when you run fast or carry a heavy load. The 16 mm hard-chrome plated rod and grease-retaining piston seal keep friction low over long service.
At 0.5 MPa this 50 mm bore delivers 981.3 N on extend and 880.8 N on retract; at 0.7 MPa the push rises to 1373.8 N. In practice, budget about 589 N of real working force at 0.5 MPa, which means it will lift roughly 50 kg vertically with a 2:1 margin (about 100 kg theoretical). Every unit carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches mount straight on the barrel.

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 MARF50X160S Is Used
Carton push-off on case packers
Pushes filled cartons off a conveyor with 981 N class force; the 160 mm stroke clears a 150 mm lane and the dual cushions tame the kick at full travel.
Food-line gate actuator
The stainless barrel and chrome rod shrug off daily washdown on a dairy or bottling line, where painted mini cylinders corrode fast.
Indexing slide on assembly fixtures
Drives a 160 mm index move on a machining or assembly fixture, with the front flange bolting straight to the base plate.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X160S the Right Cylinder?
Compare across the range at 0.5 MPa: a 40 mm MAR pushes 628.3 N and a 63 mm bore reaches 1557.9 N, so the 50 mm bore at 981.3 N sits in the workhorse middle. If your load needs under about 589 N of real force, the 40 mm could save air and money; above 981 N, step up to 63. Note a plain MAR does not lock - if air is lost the piston drifts, so add a rod lock where holding position matters. The 160 mm stroke is standard; on travel this long, guide the load or use a Y or I knuckle to keep side load off the rod, and size the 1/4" ports for enough flow at your target speed. CMSG, DMSG and EMSG switches all read the standard 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 MARF50X160S FAQ
At 0.5 MPa it pushes 981.3 N and pulls 880.8 N. At 0.7 MPa the figures rise to 1373.8 N push and 1233.1 N pull. The theoretical maximum is 200.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The MA series rolls aluminium covers and a stainless block onto a high-precision stainless tube - no tie rods - and the carbon-steel rod carries a 20 um hard-chrome plating. That riveted round shell resists washdown, humidity and outdoor exposure far better than painted bodies, and it is AirTAC's own standard mini format.
