About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-10SH
Where a fixture only has 30 mm of room to work, this cylinder fits and still trims true: the MAJ25X30-10SH runs double-acting on a 30 mm extend stroke that the stop screw pulls back to 20 mm within the ordered 10 mm window. The position magnet is factory-fitted, ready for CMSG, DMSG or EMSG sensing.
Force class is mid-range mini: 245.3 N out, 206.1 N back at 0.5 MPa, so treat about 147 N as the honest working figure - roughly a 12 kg vertical lift with margin. Air supply spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s. The stainless round barrel resists mild corrosion and washdown where painted aluminium minis do not.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-10SH Is Used
Test socket actuator
Presses a probe or socket onto a PCB or connector during electrical test; lock the trimmed stroke in place once contact depth is dialled in.
Bin gate release
Snaps open a small parts-bin gate or chute flap on demand; 245 N at 0.5 MPa is ample for a light aluminium gate.
Ejection pin
Kicks small moulded or stamped parts clear of a nest; the hard-chrome rod and stainless barrel shrug off cutting-fluid splash.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-10SH the Right Cylinder?
Start from the load: at 0.5 MPa a bore 20 unit manages 157.0 N and a bore 32 unit 402.2 N, so 25 mm is right for duty near 100-150 N. Note the adjuster is purely a mechanical limit on the extend stroke - with no air the piston can be pushed back, so position holding needs a valve solution, not this stop. FA flange and LB foot mountings plus I and Y knuckles cover most fixturing, and sensors drop onto the barrel thanks to the standard magnet.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X30-10SH FAQ
Bore 25 mm, extend stroke 30 mm adjustable down to 20 mm (10 mm window), double-acting, push 245.3 N and pull 206.1 N at 0.5 MPa, push 343.4 N at 0.7 MPa, 50 kgf theoretical max, 1/8" ports, 10 mm rod with M10x1.25 male thread.
No. The fixed anti-impact pads only decelerate the piston near each stroke end; they are not adjustable cushions. If the application needs tunable end-of-stroke damping, the MACJ cylinder adds cushioning to the same adjustable concept, and the MAD double-rod version suits through-rod guiding.
