About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-50S
Here the adjustable window matches the full stroke: the MAJ25X50-50S can be set to extend anywhere up to 50 mm, making one cylinder a stockroom cure for mis-measured fixtures. The bore 25 piston pushes 245.3 N at 0.5 MPa, so budget roughly 147 N for effective work and the stroke will stay crisp cycle after cycle.
Its stainless round barrel, rolled tight against aluminium covers, plus a hard-chrome carbon-steel rod handle damp, dusty corners that age painted minis quickly. Fixed anti-impact bumpers take the snap out of stroke ends - for true adjustable cushioning, step up to the MACJ family. The magnet is factory-fitted, so CMSG, DMSG or EMSG switches bolt on without delay.

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 MAJ25X50-50S Is Used
Test-rig strokes
Dial any extend length up to 50 mm while qualifying new jigs, then lock the stop screw for production running.
Repair-shop swaps
Replaces unknown-stroke mini cylinders in legacy fixtures without waiting weeks for a special build.
Bench pressing small parts
A practical 147 N push stakes dowels and presses light bushings on a maintenance bench.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-50S the Right Cylinder?
Compare by force before ordering: MAJ20 pushes 157.0 N at 0.5 MPa, this bore 25 does 245.3 N push / 206.1 N pull, and MAJ32 climbs to 402.2 N - pick the smallest bore that clears your load after friction. Note the adjuster is purely a mechanical end stop for the extend stroke; it cannot hold position against gravity if air is lost. Foot (LB) and flange (FA) mounts, I / Y rod knuckles and PT / G / NPT thread options on the 1/8" ports complete the order code.
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 MAJ25X50-50S FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Maximum theoretical force is 50 kgf at 1.0 MPa. Bore 25 mm, rod 10 mm, ports 1/8", rod thread M10x1.25, speed 30-800 mm/s.
FA flange, LB foot or I / Y rod knuckles; the thread comes in PT (blank), G or NPT. The piston magnet is fitted as standard, so CMSG, DMSG and EMSG switches sense end positions with no extra order and no waiting.
