About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X250-10S
Where the end position must land within a millimetre or two, the MAJ25X250-10S keeps it simple: a 250 mm double-acting stroke with a 10 mm stop-screw window for final calibration. Push force is 245.3 N and pull 206.1 N at 0.5 MPa on the 25 mm bore; at 0.7 MPa the push reaches 343.4 N.
The narrow 10 mm window suits machines where the mechanical layout sets most of the travel and the screw only fine-tunes the end stop. Construction is the familiar MA recipe - stainless round barrel, hard-chrome plated 10 mm rod, rolled aluminium covers - with fixed bumper pads at each end and a standard piston magnet for CMSG / DMSG / EMSG switches. Run filtered air at 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s; in vertical lifting it will raise parts of about 12.5 kg once the usual 2:1 margin is applied.

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 MAJ25X250-10S Is Used
Assembly press Z-stop
Setting the Z-axis stop on a small assembly press, final height adjusted by the 10 mm screw.
Bakery tray gate
Pushing a gate or lid on a bakery tray washer, 250 mm reach in a persistently wet environment.
Checkweigher hold-down
Holding cartons steady across a wide checkweigher conveyor with a 250 mm sweep.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X250-10S the Right Cylinder?
For this force band the alternatives are bore 20 at 157.0 N and bore 32 at 402.2 N (both at 0.5 MPa) - the 25 mm bore is the midpoint choice. The narrow 10 mm trim means installation must get the geometry nearly right first; the screw then dials out tolerance stack. Mount FA flange or LB foot, add I or Y knuckles if the linkage needs freedom, and remember the stop is an extend end-stop only: with air lost the rod still moves, so fit external locking where a suspended load is involved.
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 MAJ25X250-10S FAQ
Push 245.3 N / pull 206.1 N at 0.5 MPa; push 343.4 N / pull 288.5 N at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. Extend stroke 250 mm with a 10 mm adjustable window, 1/8" port, rod thread M10x1.25, speed 30-800 mm/s.
FA flange and LB foot brackets, plus I and Y rod knuckles. The piston magnet is fitted as standard, so CMSG, DMSG and EMSG switches sense position along the stainless barrel - no special-order piston needed.
