About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-20S
A compact round-body actuator for short shifts: the MAJ25X25-20S is double-acting with a 25 mm extend stroke that an external stop screw trims by up to 20 mm on site. At 0.5 MPa the bore pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) with rod speeds of 30-800 mm/s.
The riveted stainless barrel and hard-chrome plated 10 mm rod handle damp or rinsed-down corners better than painted-steel minis, a real edge in food and outdoor spots. The magnet is built in as standard, so CMSG / DMSG / EMSG switches clip straight on. The bumper pad only softens end impact, and the stop screw is a stroke end-stop rather than a brake - with air off the rod can still drift - so plan on about 147 N of real work at 0.5 MPa and add external clamping where holding matters.

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 MAJ25X25-20S Is Used
CNC fixture clamp
Clamping on a small indexing table - the 20 mm trim dials in part thickness without shims or re-plumbing.
Blister card push-off
Kicking finished blister cards at a cartoning station where 245.3 N at 0.5 MPa is ample.
Sorter gate flipper
Diverting parts on a sorting chute, with a CMSG switch confirming the trimmed end position.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-20S the Right Cylinder?
Compare both neighbours before ordering: bore 20 pushes 157.0 N at 0.5 MPa and may undersize a 245.3 N class job, while bore 32 gives 402.2 N if you want margin. Sizing around 60% of the rating points to roughly 147 N of useful force here. FA flange and LB foot mounts, plus I or Y rod knuckles, cover most fixings, and every unit carries the standard magnet for CMSG / DMSG / EMSG sensing. At a 25 mm stroke side load is rarely an issue, but keep the rod square to the load.
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 MAJ25X25-20S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push is 343.4 N (pull 288.5 N). Theoretical maximum at 1.0 MPa is 50 kgf. The extend stroke is 25 mm, trimmable by up to 20 mm with the external stop screw.
No. Every MA-series cylinder leaves the factory with a piston magnet fitted, so CMSG, DMSG or EMSG switches mount directly on the stainless barrel without special ordering.
