About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-10S
Fine positioning on a long reach is the specialty of the MAJ25X300-10S: 300 mm of stroke from a 25 mm double-acting mini cylinder, with the extend stop screw trimming depth within a 10 mm window. Push is 245.3 N and pull 206.1 N at 0.5 MPa.
The stainless round barrel shrugs off mild corrosion and washdown better than painted or bare-aluminium minis, and the hard-chrome plated rod keeps seal wear low over long travels. A standard-fit magnet feeds CMSG, DMSG and EMSG switches for repeatable end-of-stroke signals, while fixed bumpers soften both stroke ends. Plan the actual task around 147 N at 0.5 MPa rather than the full rating, and it can carry a 12 kg part weight in vertical lift once the 2:1 margin is applied.

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 MAJ25X300-10S Is Used
Dispensing depth stop on a filling head
Sets nozzle dive depth within the 10 mm window for accurate fill levels on a cosmetic bottling line.
Tote diverter on a sortation spur
Pushes totes onto a spur conveyor with 245.3 N of force; the 300 mm reach crosses two lanes from one mounting point.
Stop blade for chain conveyor indexing
Presents a stop blade to index pallets into position; a DMSG switch on the built-in magnet verifies blade status each cycle.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-10S the Right Cylinder?
Between the 20 mm bore at 157 N and the 32 mm bore at 402 N (both at 0.5 MPa), this 25 mm size offers 245.3 N - ample for diverters and depth stops once margin is applied. Over a 300 mm stroke, guide the load externally; lateral forces will bend a 10 mm rod and score the barrel seals.
The trim screw shortens extension only and acts purely as an end stop: it is not a mid-stroke lock, so a load can sag if pressure is lost. Choose FA flange or LB foot mounting, I or Y rod knuckles for swivel joints, and G or NPT ports if 1/8" PT does not match the plant.
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 MAJ25X300-10S FAQ
Double-acting, 25 mm bore, 300 mm stroke with a 10 mm adjustable window. Forces: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, 50 kgf theoretical peak at 1.0 MPa. Air supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The rolled stainless tube with a hard-chrome carbon-steel rod resists washdown chemicals, condensation and outdoor exposure, extending rod and seal life. The riveted round body is also slim and compact, and the standard magnet accepts CMSG, DMSG or EMSG switches without special ordering.
