About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X55-10S
Need a compact punch of force in a tight spot? MAJ25X55-10S is a 55 mm stroke, double-acting mini cylinder with a round stainless body, and its stop screw lets you shave the extend stroke by up to 10 mm after installation. At 0.5 MPa it develops 245.3 N - plan around 147 N of useful push to stay on the safe side.
The riveted barrel-plus-covers build keeps the profile slim for cramped machine frames, and the fixed anti-impact bumper dampens the stop at each end of travel (it is not an adjustable cushion; MACJ covers that). A magnet comes fitted as standard, so CMSG / DMSG / EMSG switches need no special piston.

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 MAJ25X55-10S Is Used
Glue valve actuator
Presses a hot-melt glue gun trigger on a carton sealing head, trimmable by 10 mm to suit different bead lengths.
Kick-off at a vision station
Nudges rejected parts off a small indexer belt right after the camera check, using part of the 245.3 N push.
Capsule lid press
Snaps lids onto coffee capsule trays with roughly 12 kg of vertical force held in reserve (245.3 N less a 2:1 margin).
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X55-10S the Right Cylinder?
For short 55 mm moves, check whether bore 20 (157.0 N at 0.5 MPa) would do - or jump to bore 32 for 402.2 N when 245.3 N is marginal. This stroke sits well inside the 300 mm standard for the bore, so it ships as a catalogue part. The stop screw is a mechanical limit on the extend end; it will not clamp a load mid-stroke, and with air lost the rod coasts freely. FA flange or LB foot mounting plus I / Y rod knuckles cover most fixturing. Supply 40 um filtered air at 0.15-1.0 MPa (22-145 psi) and stay between 30 and 800 mm/s.
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 MAJ25X55-10S FAQ
This bore pushes 245.3 N and pulls 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N out and 288.5 N back, with a 50 kgf theoretical maximum at 1.0 MPa. Stroke is 55 mm (trimmable by 10 mm), rod 10 mm, ports 1/8", pressure 0.15-1.0 MPa (22-145 psi).
It is the adjustable-stroke window: an external stop screw shortens the extend stroke by up to 10 mm from the full 55 mm, set on the machine without disassembly. Retraction is unaffected, and the anti-impact bumper pads stay fixed.
