About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X200-100S
With 100 mm of trim on a 200 mm nominal travel, the MAJ25X200-100S covers any extend length from 100 to 200 mm, set by an external stop screw at the machine. The 25 mm bore generates 245.3 N pushing at 0.5 MPa, roughly 25 kgf of raw force, so plan continuous work around 147 N or lift close to 12 kg vertically with a 2:1 margin.
The stainless round barrel and hard-chrome plated rod shrug off washdown and damp shop air, a real edge over painted minis in food and outdoor cells. Travel ends land on fixed anti-impact pads that soften deceleration without cushion needles, and because the magnet is built in as standard, CMSG, DMSG or EMSG switches mount with no special-order piston. Ports are 1/8".

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 MAJ25X200-100S Is Used
Roller-conveyor tote stop
Acts as a movable stop for totes arriving at a pick station; the 100 mm window lets engineers retune the stop point per SKU without changing hardware.
Case-packer flap tucker
Folds top flaps on cartons at a case packer; when carton heights change on the line, the extend stop is retimmed on site.
Sample tray elevator
Raises tray stacks of about 12 kg between a centrifuge and a plate reader, using the 245.3 N push with a 2:1 vertical margin.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X200-100S the Right Cylinder?
Step down to the 20 mm bore (157 N push at 0.5 MPa) if the workpiece is light; step up to 32 mm (402.2 N) when 245.3 N leaves too little headroom. Run air between 0.15-1.0 MPa (22-145 psi) and keep speed within 30-800 mm/s. The stop screw sets the extend endpoint only - on air loss the piston still drifts, so add an external stop where load holding matters.
Mount with FA flange or LB foot, and add I or Y rod knuckles where the load pivots. Over a 200 mm stroke the 10 mm rod should see mainly axial load; guide side forces externally to protect the bearing.
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 MAJ25X200-100S FAQ
At 0.5 MPa the 25 mm bore pushes 245.3 N and pulls 206.1 N; at 0.7 MPa those rise to 343.4 N push and 288.5 N pull. The theoretical maximum is 50.0 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof.
The rolled stainless barrel resists corrosion in washdown and outdoor air, and the 20 um hard-chrome rod keeps friction low across 30-800 mm/s. The magnet is standard, so CMSG, DMSG and EMSG switches give extend/retract signals straight away.
