About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-50S
When one machine runs several recipes, a fixed stroke forces shimming; the MAJ25X225-50S instead carries an external stop screw that shortens the extend stroke anywhere inside the 50 mm window, in minutes, with a screwdriver. Double-acting throughout, the 25 mm bore pushes 245.3 N at 0.5 MPa and 343.4 N at 0.7 MPa, and retracts with 206.1 N behind it.
The round stainless barrel is rolled onto aluminium covers, so the body stays slim inside tight machine frames. Fixed anti-impact pads decelerate the rod at both ends, acting as a mechanical soft stop rather than an adjustable cushion. For sizing, budget about 147 N for real work at 0.5 MPa, which is roughly a 12 kg vertical lift with a 2:1 margin. The standard piston magnet feeds CMSG or EMSG switches without any special order.

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 MAJ25X225-50S Is Used
Palletizer layer pusher
Squares carton layers on a palletizer infeed; 343 N at 0.7 MPa moves full layers without stalling.
Sample tray indexer
Steps lab sample trays 225 mm between stations, where the 50 mm trim absorbs fixture tolerances.
Recipe-change glue head
Sets glue-head approach depth per recipe; technicians re-trim the 50 mm window instead of swapping cylinders.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-50S the Right Cylinder?
Compare before ordering: at 0.5 MPa a bore 20 unit makes 157 N and a bore 32 makes 402 N, so a mid-duty job may drop or rise a bore size. With 225 mm of rod exposed, keep the tooling guided externally, since bending loads will wear the 10 mm chrome rod and its seals prematurely. The stop collar holds position at the end of travel only; under air loss the piston can still be driven back, so do not rely on it as a brake. FA flange and LB foot mounts suit fixed frames, while I or Y knuckles take up small misalignment; the built-in magnet works with DMSG switches straight from stock.
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 MAJ25X225-50S FAQ
At 0.5 MPa it produces 245.3 N forward and 206.1 N back; at 0.7 MPa, 343.4 N forward; theoretical peak 50 kgf at 1.0 MPa. The 25 mm bore takes 1/8" ports, carries a 10 mm rod with M10x1.25 male thread, runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and its extend stroke trims within the 50 mm window.
No. The MAJ carries fixed anti-impact bumper pads that cushion the last part of travel; for adjustable air cushioning you would step up to the MACJ family. The pads need no setting and cannot leak, which suits high-cycle packaging stations.
