About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X60-40S
Stroke lengths that change with the product are exactly why the 40 mm window exists: the extend stroke of this 25 mm bore cylinder can be set anywhere from 20 mm to 60 mm without ordering a new part. Force at 0.5 MPa is 245.3 N push; keep the applied load around 147 N so seals and bushings last. The round stainless body resists corrosion far better than painted-steel mini cylinders in wet or food-area duty.
Inside, a heterogeneous two-way seal stores grease on the hard-chrome plated rod for long life between services. The piston magnet is standard equipment, so CMSG / DMSG / EMSG switches mount without special ordering. Air: 0.15-1.0 MPa (22-145 psi), filtered to 40 um, speed 30-800 mm/s.

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.

Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X60-40S the Right Cylinder?
If 245 N at 0.5 MPa over-serves the job, the 20 mm bore's 157 N will do; if the load grows, step to the 32 mm bore and 402 N. Because the trim screw merely stops the rod at end of extend, use a locking valve for any load-holding need. At a 60 mm span the 10 mm rod has no internal guiding, so add external guides when side loads appear. Magnet is standard, mounts are FA / LB with I / Y knuckles, and the air port is 1/8".
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.
