About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-10S
Fine positioning is the brief for the MAJ25X225-10S. It is double acting like any MA cylinder, but the external stop screw narrows the extend stroke to within a 10 mm window of your setting - enough to take up tooling tolerance or set a repeatable standoff without re-plumbing. The 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa across a 30-800 mm/s speed band.
The riveted round body pairs a stainless barrel with a hard-chrome plated carbon-steel rod, so it tolerates damp, washed-down corners that chew up painted minis. Vertically, the 0.5 MPa push equates to about 25 kgf; halve that for margin and you can lift roughly 12 kg with a 2:1 safety factor. Every unit carries a built-in magnet as standard equipment, so CMSG / DMSG / EMSG switches drop straight on for end-of-travel 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 (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 MAJ25X225-10S Is Used
Lab dosing probe
Sets a shallow, repeatable dip depth for a sampling probe in a benchtop filling rig, trimmed precisely inside the 10 mm window.
Labelling nip roller
Applies even nip pressure on a labelling head, where the 10 mm trim keeps contact force consistent as label rolls wear down.
Vision check stop
Stops and squares small electronics trays at a camera inspection post; 245 N of push is ample against a 300 g tray's friction.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-10S the Right Cylinder?
Bore 25 sits mid-range: the 20 mm MAJ offers 157.0 N push at 0.5 MPa and the 32 mm steps up to 402.2 N, so 245.3 N lands between them for medium ejection and clamping. Over a 225 mm stroke, guide the load externally - the 10 mm rod takes little side bending. Because the 10 mm window is a trim rather than a lock, it will not hold the piston against drift when air is lost, so bleed-down safety belongs to a valve. FA flange or LB foot mounting plus I / Y rod knuckles suit most small fixtures, and the standard magnet makes sensing bolt-on with CMSG, DMSG or EMSG switches.
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 MAJ25X225-10S FAQ
Double acting on filtered air at 0.15-1.0 MPa (22-145 psi). At 0.5 MPa expect 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull; theoretical ceiling at 1.0 MPa is 50 kgf. Port size is 1/8", rod 10 mm with M10x1.25 thread, speed 30-800 mm/s, and the extend stroke adjusts within the ordered 10 mm window.
No. The piston magnet is standard equipment on every MAJ cylinder, so CMSG, DMSG and EMSG switches clip onto the stainless barrel without a special-order piston or factory delay.
