About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X150-40S
Retune the machine without touching the order book - the 40 mm window on this 25 mm MAJ lets maintenance set the extend stroke anywhere between 110 and 150 mm via the external stop screw. At 0.5 MPa the bore pushes 245.3 N and pulls 206.1 N, a class that suits gates, kickers and light clamps.
The riveted stainless round body stays slim where profile cylinders cannot, and the hard-chrome plated rod resists wear in gritty or damp air. Fixed bumper pads cushion both stroke ends - for adjustable deceleration, step up to the MACJ series. For lift duties, the rated push equates to about 25 kg vertical; keep real lifts near 12 kg for a comfortable margin.

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 MAJ25X150-40S Is Used
Tray stop on a pharmaceutical blister packer
Halts blister trays at a print-and-verify station, where the 40 mm window compensates for different tray formats on the same machine.
Dosing gate on a granulate hopper
Opens and closes a slide gate under a plastics dosing hopper; the stainless barrel stands up to abrasive dust that would chew painted bodies.
Hold-down shoe on a benchtop heat-staking press
Presses a staking shoe onto terminals with 343.4 N at 0.7 MPa, trimming the approach stroke in 40 mm range to shorten cycle time.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X150-40S the Right Cylinder?
Check the neighbours before committing: 20 mm gives 157 N at 0.5 MPa and 32 mm gives 402.2 N, so the 25 mm at 245.3 N covers the broad middle. With a 40 mm window you give up travel when trimmed - confirm the minimum stroke your mechanism tolerates before ordering. The adjuster is a hard extend stop, so a hanging load will sag if supply air fails; add a valve with pilot check where holding matters.
At 150 mm of stroke, support long side-loaded tooling externally rather than leaning on the 10 mm rod. The standard magnet means CMSG, DMSG or EMSG switches mount on the barrel from day one.
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 MAJ25X150-40S FAQ
It delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N and 288.5 N at 0.7 MPa, and a 50 kgf theoretical maximum at 1.0 MPa. Stroke is 150 mm with the extend side trimmable over a 40 mm window, port 1/8 in, rod 10 mm on M10x1.25 thread, and proof pressure 1.5 MPa (215 psi).
FA flange and LB foot mounts, plus I and Y rod knuckles for pivoting loads; the adjustable version omits the SDB double-rod arrangement. The magnet ships standard, so CMSG, DMSG and EMSG switches bolt straight on, and every port on this 25 mm bore is 1/8 in.
