Airtac MARF Stainless Steel Mini Air Cylinder MARF63X30S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X30S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 30mm 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 MARF63X30S
Just 30 mm of travel, yet the strongest force class the MA series offers: the MARF63X30S is a double-acting mini cylinder with variable cushions at both ends and a front flange formed on the front cover, letting the cylinder land directly on the machine plate without a loose mounting foot. At 0.5 MPa it develops 1557.9 N of push and 1457.4 N of pull.
The stainless barrel and hard-chrome plated rod are the reasons to pick it over an aluminium mini in food, washdown or outdoor settings. For sizing, treat about 935 N as the working force at 0.5 MPa - enough to raise roughly 79 kg against gravity with a 2:1 margin - and use the standard piston magnet with CMSG / DMSG / EMSG switches for end-of-stroke detection.

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 MARF63X30S Is Used
Die carousel index pin
Pins a rotating die carousel in position between indexing moves on a compact press; 1558 N at 0.5 MPa seats the pin hard every cycle.
Tray denester on a food line
Fires a denesting blade under the top tray of a stacking magazine on a food packing line, where the stainless body tolerates daily washdown.
Clamp on a tube welding jig
Clamps a tube joint into a welding jig; the short 30 mm stroke cycles fast and the cushion takes the snap out of clamp-down.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X30S the Right Cylinder?
At 30 mm stroke this is a locking, clamping and ejecting unit. The 50 mm MAR covers the same stroke with 981.3 N push at 0.5 MPa if your load is lighter; nothing in the MAR range is bigger than 63 mm, and the related MAC adds a separate flange or foot if you prefer conventional mounting hardware. Air drives both directions and the cushion only softens the last few millimetres, so on air loss the rod will drift - specify a rod lock whenever the load must stay put unattended.
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 MARF63X30S FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181 N push, 2040.3 N pull. Theoretical peak 317.7 kgf at 1.0 MPa. Ports are 1/4 inch, the rod is 16 mm with an M14x1.5 male thread, and 0.15-1.0 MPa (22-145 psi) is the working band.
Yes, the magnet is standard equipment on every MAR piston, not a paid option. Clip a CMSG, DMSG or EMSG switch onto the stainless barrel at either cushioned end or anywhere along the 30 mm stroke, and reposition it later without opening the cylinder.
