About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X35-30S
One stop screw, 30 mm of tuning room: the MAJ25X35-30S runs a 35 mm double-acting stroke that crews can shorten on the fly anywhere inside its 30 mm adjust window. The 25 mm bore yields 245.3 N push and 206.1 N pull at 0.5 MPa and 343.4 N push at 0.7 MPa, on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
Keep real workloads near 147 N at 0.5 MPa and the cylinder holds its cycle without hunting. The riveted stainless barrel and hard-chromed rod cope with coolant mist around machine tools, while fixed anti-impact pads take the sting out of each stroke end. The piston magnet is included from the factory, so wiring a CMSG, DMSG or EMSG switch is a clip-on job.

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 MAJ25X35-30S Is Used
Accumulation stopper
A drop-in stopper halts cosmetic cartons on an accumulation conveyor; the 30 mm window lets the stop blade sit flush for different carton heights.
Label applicator press
The pad presses self-adhesive labels onto jars with about 147 N of working force, and EMSG sensing confirms full extension before release.
Fixture height setter
On a drill fixture the rod raises a workpiece stop so operators can reset for a new bracket size without shimming the plate.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X35-30S the Right Cylinder?
Between the 157.0 N of a bore-20 unit and the 402.2 N of a bore-32 unit, this 25 mm cylinder covers medium press and clamp duties at 0.5 MPa. The wider 30 mm window pays off when fixtures are swapped often and the home position shifts; treat the screw as an extend-side end stop, never a mid-stroke lock, and support off-axis loads with external bushings. Connections are 1/8" with an M10x1.25 male rod thread; FA and LB mountings plus I or Y knuckles suit most jig frames.
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 MAJ25X35-30S FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical maximum at 1.0 MPa: 50 kgf. Stroke is 35 mm, trimmable up to 30 mm shorter on extend by the stop screw, at 30-800 mm/s.
No. The MAJ carries fixed anti-impact pads that only decelerate the piston at each end; they cannot be tuned the way the adjustable cushions on the MACJ family can. If your cycle demands regulated end damping, choose MACJ instead.
