Airtac MARF Stainless Steel Mini Air Cylinder MARF50X75S
The AirTAC MARF Stainless Steel Mini Air Cylinder MARF50X75S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 75mm 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 MARF50X75S
With a 75 mm stroke and the mounting flange already rolled into the front cover, the MARF50X75S keeps installation to four bolts. Double acting on air in both directions, it delivers 981 N of push and 881 N of pull at 0.5 MPa, with a variable cushion at each end you can needle down to soften the stop. The round stainless barrel and hard-chrome 16 mm rod take moisture, splashes and outdoor air in their stride - an edge painted mini cylinders lose fast.
Because the magnet ships inside the piston as standard, position switches are a bolt-on, not a special order. Run it anywhere from 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MARF50X75S Is Used
Tote diverter arm
Swings totes between two roller lanes in a parcel hub; 981 N of push at 0.5 MPa clears a 15 kg tote against belt friction with margin.
Guard-gate opener
Opens a hinged interlock gate on a press cell; the cushion takes the slam out of the 75 mm swing so the latch does not hammer.
Carton flap tucker
Folds the final flap on a pharma cartoner; the stainless body survives the alcohol wipe-downs the line gets each shift.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X75S the Right Cylinder?
A 40 mm MAR bore (628 N push at 0.5 MPa) may do the job in a tighter space; if your load needs more than about 981 N, move up to the 63 mm bore at 1558 N. Remember the MAR does not lock - on air loss the rod drifts with the load, so add a rod lock where a raised part must stay put. If a later machine variant needs a foot or rear-eye mount instead, the MAC series carries those as separate accessories; the MARF keeps its bracket built in. Ports on this bore are 1/4 inch.
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 MARF50X75S FAQ
Use 981.3 N push and 880.8 N pull at 0.5 MPa, or 1373.8 N push and 1233.1 N pull at 0.7 MPa. Theoretical peak at 1.0 MPa is 200.1 kgf. Pressure range is 0.15-1.0 MPa (22-145 psi) and the proof rating is 1.5 MPa (215 psi). For real work, keep the load near 589 N.
Each end has a variable air cushion with its own needle screw. On first run-up, bleed the needles slightly closed, watch the stroke, then open until end-of-stroke noise and rebound disappear. That lets you run up to 800 mm/s or carry heavier loads without hammering the covers.
