About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X75-30S
The MAJ25X75-30S is AirTAC's round-body MAJ mini cylinder: double-acting, 25 mm bore, 75 mm stroke, with an external stop screw that trims the extend stroke anywhere inside the ordered 30 mm window. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N, so planning around roughly 147 N of real work at 0.5 MPa leaves a healthy margin for friction and side loads.
The riveted stainless barrel and hard-chrome 10 mm rod stand up to damp or washed-down spots where painted mini cylinders corrode, and the fixed anti-impact pad softens stroke-end deceleration without any extra cushion hardware. A magnet ships in the piston as standard, so CMSG, DMSG or EMSG switches clip straight on. Running 30-800 mm/s at 0.15-1.0 MPa (22-145 psi), it also lifts about 13 kg vertically when the full push force is used with a 2:1 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 MAJ25X75-30S Is Used
Pick-and-place of die-cast fittings
Moves aluminum die-cast fittings between two bench fixtures; the 30 mm trim lets the operator set the drop height exactly and the magnet feeds a CMSG switch for part-present confirmation.
Terminal crimping mini press
A small bench press that crimps wire terminals: 245.3 N at 0.5 MPa is enough for light crimps, and the stop screw caps the extend stroke so over-crimping is impossible.
Packaging line ejector
Pushes reject cartons off a conveyor; the stainless barrel tolerates periodic washdown and the fixed bumper pad stops the pusher head from slamming at stroke end.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X75-30S the Right Cylinder?
Sizing check: at 0.5 MPa a 20 mm bore MAJ gives 157 N push and a 32 mm bore gives 402.2 N, so this 25 mm model's 245.3 N sits in the middle for medium grippers and clamps. Port size is 1/8 inch, rod thread M10x1.25. Remember the stop screw is a mechanical end stop for the extend stroke, not a lock - if air pressure drops, the piston can still drift. Pick FA flange or LB foot to suit the fixture; I and Y rod knuckles are available. Sensor-ready out of the box thanks to the standard magnet.
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 MAJ25X75-30S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. The extend stroke can be trimmed anywhere within the ordered 30 mm window via the external stop screw; it cannot be lengthened past 75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed range is 30-800 mm/s.
It is a compact round-body cylinder: a stainless-steel barrel with aluminium-alloy covers rolled on, a hard-chrome plated carbon-steel piston rod, and fixed anti-impact bumper pads at the stroke ends. Every MAJ ships with a built-in magnet, so CMSG, DMSG or EMSG reed/solid-state switches mount directly on the barrel with no special-order piston.
