Airtac MARF Stainless Steel Mini Air Cylinder MARF63X225S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X225S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 225mm 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 MARF63X225S
Big thrust in a slim round body: this 63 mm MAR delivers 1558 N forward and 1457 N on retract at 0.5 MPa, and 2181 N at 0.7 MPa when the supply is turned up - the strongest bore in AirTAC's MAR range. Double acting with a variable cushion at each end, it carries its front flange as part of the cover, so mounting means four bolts and no accessory bracket.
The riveted stainless tube and hard-chrome steel rod keep working in humid, splashy corners that pit painted minis, while the cushion needles let you bleed end-of-stroke shock until heavy loads land soft. In practice count on roughly 935 N of usable push at 0.5 MPa, enough to lift about 79 kg vertically with a 2:1 safety margin; the piston magnet is standard equipment and pairs with CMSG, DMSG or EMSG switches.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MARF63X225S Is Used
Aluminium scrap ram
Densifies aluminium offcuts in a machine-shop scrap press, drawing on 2181 N of push at 0.7 MPa for the densest packs.
Stone saw hold-down
Clamps granite blanks against a wet cutting table, where the stainless body tolerates constant coolant mist without rusting.
Chilled dock gate
Swings a heavy cooler door on a refrigerated dock, the 63 mm bore sized so humid supply air at 0.5 MPa still leaves 935 N of working thrust.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X225S the Right Cylinder?
Nothing in the MAR line out-punches 63 mm: at 0.5 MPa it turns 1558 N of push versus 981 N from a 50 mm bore, so step down only if the load drops below about 900 N. Should you need more than 2181 N at 0.7 MPa, ask about AirTAC's larger cylinder families instead of upsizing within MAR.
The 225 mm stroke is standard, ports are 1/4" PT (G and NPT on request), and the rod thread is M14x1.5 for I or Y knuckles. The front flange is built in - do not add a separate flange accessory - and although the cushion softens a heavy load's arrival, the piston drifts whenever air pressure is lost, so a rod lock is the answer where parking matters.
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 MARF63X225S FAQ
Measure it: 1557.9 N push and 1457.4 N pull at 0.5 MPa, 2181.0 N and 2040.3 N at 0.7 MPa, and 317.7 kgf theoretical peak at 1.0 MPa. Run it anywhere in the 0.15-1.0 MPa (22-145 psi) window at 30-800 mm/s, through 1/4" ports on the 225 mm standard stroke.
No. Every MA-series piston carries its magnet as standard, so CMSG, DMSG or EMSG reed and Hall switches clip straight onto the stainless barrel with no special-order piston, no drilling and no extra kit. Mount them anywhere along the stroke the switch datasheet allows.
