Airtac MARF Stainless Steel Mini Air Cylinder MARF63X175S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X175S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm 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 MARF63X175S
The MARF63X175S puts AirTAC's biggest MAR bore to work: 63 mm of piston area delivering 1557.9 N of push and 1457.4 N of pull at 0.5 MPa (72.5 psi), rising to 2181.0 N at 0.7 MPa. This is a double-acting, round-body cylinder with a variable air cushion at both ends and its own front-flange cover, so it bolts straight to the machine with no separate foot or bracket. Because the 175 mm stroke sits well inside the 500 mm standard limit for this bore, it ships as a catalogue item, not a special.
Under the skin there is a stainless-steel barrel rolled together with aluminium-alloy covers and a hard-chrome plated 16 mm rod, a combination that shrugs off washdown and damp plant air far better than painted minis. Sized for real work, plan on roughly 935 N of usable push at 0.5 MPa rather than the full rating, which equates to lifting about 79 kg vertically with a 2:1 margin. A magnet comes built in as standard, so CMSG, DMSG or EMSG switches clip on whenever you need position signals.

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 MARF63X175S Is Used
Bottling line reject gate
A front-flanged 63 mm pusher kicks cracked bottles off a filler conveyor at 30-800 mm/s; the variable cushion catches the container instead of hammering the covers.
Pallet elevator assist
With about 79 kg of vertical lift per cylinder at half its stall equivalent, a pair of MARF63X175S units raise a pallet jig on a low-cost lift table.
Grain diverter gate
Slides a dust-tight diverter on an outdoor grain auger; the stainless barrel and chrome rod shrug off weather that pits painted-steel minis in a single season.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X175S the Right Cylinder?
Step down to the 50 mm bore (981.3 N push at 0.5 MPa) if the load is under about 590 N, and step up to nothing - 63 mm is the largest MAR offers. If you need a foot or side mount instead of the front flange, look at the MAC family, which takes separate flange and foot brackets; MACD adds a second rod where anti-rotation matters.
Note the plain MAR drifts if air is lost; the cushion softens stroke ends but is not a lock, so add a rod lock for safe load holding. The 175 mm stroke calls for clean rod alignment - keep side load off the chrome rod or use a guide, and match Y or I knuckles on the M14x1.5 rod thread.
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 MARF63X175S FAQ
At 0.5 MPa (72.5 psi) it pushes with 1557.9 N and pulls with 1457.4 N. Raise supply to 0.7 MPa and the push reaches 2181.0 N (pull 2040.3 N), with a theoretical maximum of 317.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
Yes. The barrel is stainless steel rolled onto aluminium-alloy covers, and the 16 mm rod carries 20 um of hard chrome. That trio resists the rust and pitting that attack painted or plain aluminium mini cylinders in washdown, food and outdoor duty.
