About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-10S
When the job is a 25 mm nudge rather than a long push, this compact MAJ keeps a 25 mm bore in the smallest practical round envelope. Double-acting, it drives 245.3 N out at 0.5 MPa and returns on 206.1 N, with an external stop screw that trims the extend stroke anywhere inside the 10 mm window, handy for dialling in ejection or detection positions.
The riveted stainless barrel and hard-chrome rod suit greasy machine interiors where painted bodies chip and flake. Fixed bumper pads take the snap out of stroke ends without any cushion plumbing. Expect about 147 N of genuinely usable force at 0.5 MPa, close to a 12 kg vertical lift at a 2:1 margin, and the standard piston magnet means CMSG, DMSG or EMSG switches clip straight on.

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 MAJ25X25-10S Is Used
Sorting flap on chute
Flips a diverter flap between two chutes; 245 N at 0.5 MPa actuates a spring-loaded gate briskly.
Part-present ejection pin
Ejects small machined parts from a fixture nest; the 10 mm window sets the exact eject height per part.
Jam-detect target actuator
Moves a metal target into a photo-eye path for jam detection on filling machines, cycling 30-800 mm/s.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X25-10S the Right Cylinder?
At 0.5 MPa the next size down, bore 20, yields about 157 N and bore 32 about 402 N, so pick 25 mm when the load sits between them and the stroke must stay short. The trim screw defines the extend end stop; it is not a mid-stroke lock, and with pressure dropped the piston can still be displaced, so interpose a valve if holding matters. LB foot or FA flange mounting keeps the short body rigid, and I or Y rod knuckles forgive slight linkage misalignment. Built-in magnet plus DMSG sensing gives a position signal without ordering any options.
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 MAJ25X25-10S FAQ
Bore 25 mm, stroke 25 mm, extend stroke trimmable within a 10 mm window. Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N at 0.7 MPa; theoretical maximum 50 kgf at 1.0 MPa. Ports 1/8", rod thread M10x1.25, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Choose the FA flange for face bolting or the LB foot for base mounting, with I and Y rod knuckles available for linkage work. Because the magnet is built in as standard, CMSG, DMSG or EMSG switches mount on the barrel out of the box; no special piston order is needed.
