About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-30S
Mechanisms that need a little positional give, not a broad sweep, suit the MAJ25X225-30S: double-acting power in both directions, plus a stop screw that trims the extend stroke anywhere within the ordered 30 mm window. This 25 mm bore generates 245.3 N of push and 206.1 N of pull at 0.5 MPa, which translates to about 12 kg of vertical lift once you keep a 2:1 margin.
Durability details matter in this size class: a high-precision stainless barrel rolled together with aluminium covers, and a carbon-steel rod hard-chrome plated to 20 um against wear and mild corrosion. Fixed bumper pads take the sting out of stroke ends - deceleration only, since adjustable cushioning belongs to the MACJ series. The onboard magnet comes as standard and supports CMSG / DMSG / EMSG switches without special ordering.

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 MAJ25X225-30S Is Used
Sorting flap
Deflects small hardware such as screws and inserts between two bins on an assembly bench, the 30 mm window setting flap over-travel.
Bench press pre-position
Holds the ram of a small arbor press just above the workpiece via the stop screw until the operator cycles the power stroke.
Leak-test clamping
Applies repeatable 245 N clamping on a leak-test fixture for brass fittings, the magnet confirming full clamp before testing starts.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-30S the Right Cylinder?
Compare before committing: the 20 mm MAJ pushes 157.0 N and the 32 mm MAJ 402.2 N at 0.5 MPa, so this 245.3 N bore is the middle choice for ejection, gating and light clamping. On a 225 mm stroke keep lateral load off the rod by guiding the part externally. The 30 mm adjuster is a mechanical extension stop, not a brake - with air lost, the piston drifts, so treat holding as a valving problem. FA flange and LB foot options, I and Y knuckles, and the standard-fitted magnet (CMSG / DMSG / EMSG ready) round out the mounting and sensing picture.
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 MAJ25X225-30S FAQ
At 0.5 MPa, 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull; 50 kgf theoretical maximum at 1.0 MPa. Double acting, on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, speed 30-800 mm/s, 1/8" ports, 10 mm rod with M10x1.25 thread, extend stroke trimmable within the 30 mm window.
FA flange and LB foot mountings cover fixed installation, while I and Y rod knuckles absorb small misalignment at the rod end. The adjustable-stroke version has no SDB option, and the built-in magnet is fitted as standard, so CMSG, DMSG or EMSG switches can be added at any time.
