About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X450-10S
Double acting through and through, the MAJ25X450-10S pushes with 245.3 N at 0.5 MPa and pulls 206.1 N, while an external stop screw lets you trim the extend stroke down by up to 10 mm after installation. A practical ceiling for continuous work at 0.5 MPa is roughly 147 N, which keeps the cylinder well inside its 50 kgf theoretical limit.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated 10 mm rod, so damp washdown corners and outdoor frames do not eat the tube the way they attack painted minis. At 450 mm of travel - a made-to-order stroke beyond the 300 mm standard for bore 25 - the fixed bumper pads take the sting out of stroke ends, and speed spans 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.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X450-10S Is Used
Gate indexing on a packaging line
Trim the extend stroke within 10 mm to match gate pockets; around 147 N of dependable push slides stainless gates smoothly at 0.5 MPa.
Kick-off station on a bottle conveyor
245 N at 0.5 MPa nudges PET bottles off a 300 mm lane, and the 450 mm reach crosses the machine frame without a second actuator.
Sample tray lift in a lab autoloader
The bore gives a 25 kg vertical force equivalent at 0.5 MPa; halve it to roughly 12 kg of real lift margin for tray pickups.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X450-10S the Right Cylinder?
At 245.3 N push and 206.1 N pull on 0.5 MPa, bore 25 sits between the 20 mm bore (157.0 N) and the 32 mm bore (402.2 N), so step down or up depending on the margin you want. Keep in mind the stop screw is a mechanical end stop only: if air pressure drops, the rod still drifts, so never count on it to park a load. FA flange and LB foot mounts fit the frame options, the magnet is already in the piston for CMSG / DMSG / EMSG switches, and with a 450 mm stroke you should guide the load externally so side load never reaches the 10 mm rod.
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 MAJ25X450-10S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull. Theoretical maximum at 1.0 MPa is 50 kgf. Air ports are 1/8 inch on both covers, the rod is 10 mm with an M10x1.25 male thread, and the extend stroke can be shortened by up to 10 mm with the stop screw.
No. Every MAJ ships with the piston magnet built in, so CMSG, DMSG or EMSG switches clip straight onto the stainless barrel for end-of-stroke signaling. The trim screw only limits the extend stroke; it does not shift switch positions.
