About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-10S
Short-throw clamping is this model's home ground. The MAJ25X50-10S is a double-acting mini whose stop screw trims the extend stroke inside a 10 mm window - the ordered 50 mm of travel can be backed off to 40 mm on the machine without touching the plumbing. Bore 25 puts out 245.3 N at 0.5 MPa (343.4 N at 0.7 MPa), enough to lift about 12.5 kg vertically once a 2:1 margin is kept.
The body is a riveted stainless tube with aluminium-alloy covers, a hard-chrome plated 10 mm carbon-steel rod, and grease-holding two-way piston seals that keep friction low over long cycle lives. Fixed anti-impact pads absorb end-of-stroke shock (they decelerate only; adjustable cushioning lives in the MAC family). The piston magnet is standard, so CMSG/DMSG/EMSG switches mount with no option order. Air supply runs 0.15-1.0 MPa (22-145 psi) with speeds of 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 MAJ25X50-10S Is Used
Drill jig clamp
Clamps aluminium brackets in a CNC drill jig; 245.3 N of hold at 0.5 MPa with the stop trimmed so the pad never over-travels into the part.
Dowel pin ejector
Kicks dowel pins out of an assembly fixture after press-fit; the 10 mm trim keeps ejection length repeatable batch after batch.
Benchtop crimp anvil
Feeds a light crimp die on a benchtop terminal press; end position is verified by a CMSG switch riding the standard-fit magnet.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-10S the Right Cylinder?
Compare first: bore 20 of this family gives 157.0 N at 0.5 MPa while bore 32 reaches 402.2 N, so bore 25 at 245.3 N is the middle choice. The 10 mm window lets you back the extend stroke off from 50 mm to as little as 40 mm by screwing the stop in - it cannot add travel. FA flange or LB foot carries the body; I and Y knuckles suit the rod end. Keep in mind the adjuster is an end stop, not a brake: cut air and the piston still moves.
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 MAJ25X50-10S FAQ
The MAJ25X50-10S pushes 245.3 N and pulls 206.1 N at 0.5 MPa; at 0.7 MPa those become 343.4 N push and 288.5 N pull; theoretical peak for this bore is 50 kgf at 1.0 MPa.
Air ports are 1/8" on both covers, the piston rod is 10 mm with an M10x1.25 male thread, and the mounting points cover FA flange, LB foot plus I and Y rod knuckles.
