Airtac MARF Stainless Steel Mini Air Cylinder MARF50X80S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X80S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 80mm 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 MARF50X80S
An 80 mm stroke on a 50 mm bore, the MARF50X80S brings its own front flange, so the machine builder skips the loose flange plate entirely. Double acting with a variable cushion at both ends, it puts out 981 N pushing and 881 N pulling at 0.5 MPa. The rolled stainless barrel and hard-chrome 16 mm rod stand up to washdown and damp corners where painted-steel minis start to rust.
Practical sizing: hold the applied load near 589 N at 0.5 MPa and the cylinder runs cool and long; the full 981 N is there for peaks. This bore also lifts about 100 kg straight up at 0.5 MPa, or 50 kg if you keep a 2:1 margin. Because the magnet is fitted as standard, CMSG, DMSG and EMSG switches clip straight over 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 MARF50X80S Is Used
Capper press head
Presses screw caps home on 5 litre water bottles; the roughly 50 kg vertical lift margin at 0.5 MPa covers cap torque loads with room to spare.
Pallet squaring pusher
Squares layer-formed cartons against stops in a palletizing cell; the 80 mm stroke reaches across the layer edge in one move.
Index dial nudge
Advances a rotary indexing table one station per cycle; needle-set cushions stop the dial without overshoot at 800 mm/s.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X80S the Right Cylinder?
Compare before you commit: the 40 mm bore pushes 628 N at 0.5 MPa if your load is lighter, while the 63 mm bore delivers 1558 N for heavier presses. At 80 mm of stroke, keep side loads off the rod - guide the load in external slides or bushings, since bending moments shorten rod and bearing life quickly. This model holds nothing on air loss; the rod moves with the load when pressure drops, so spec a rod lock for suspended loads. Adjustment is limited to the two cushion needles - everything else is set by the bore.
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 MARF50X80S FAQ
At 0.5 MPa: 981.3 N push, 880.8 N pull. At 0.7 MPa: 1373.8 N push, 1233.1 N pull. Theoretical maximum force at 1.0 MPa is 200.1 kgf. The cylinder runs on 0.15-1.0 MPa (22-145 psi), tolerates 1.5 MPa (215 psi) proof, and works from -20 to +70 C.
The front flange is machined into the front cover as an integral part, so there is no separate FA, LB or SDB bracket to order - the MARF bolts directly to your plate. The 16 mm rod takes M14x1.5 threads, and I or Y rod knuckles still fit if the job needs a pivoting joint.
