About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X500-100S
Long travel in a compact round body: the MAJ25X500-100S runs a 500 mm made-to-order stroke (beyond the 300 mm standard for bore 25) with a 100 mm extend-trim window, so reach can be set anywhere from 500 down to 400 mm on site. Push at 0.5 MPa is 245.3 N - work with roughly 147 N and respect the long rod.
A 10 mm rod over half a metre is the honest design challenge: keep side loads near zero and guide the load externally, because slender rods bend long before the barrel complains. In return, the stainless tube and hard-chrome plated rod resist corrosion along the whole travel, fixed bumpers soften the ends, and the standard magnet pairs directly with CMSG / DMSG / EMSG switches.

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 MAJ25X500-100S Is Used
Cross-line transfers
Pushes light trays across a 400-500 mm gap between conveyors with a long, low-profile round body.
Rack-lane ejectors
Clears cartons from deep storage lanes; the stainless barrel copes with unheated, humid warehouse air.
Machine-gate lifts
Raises interlocked safety gates of about 12.5 kg with margin on a long, vertically guided column.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X500-100S the Right Cylinder?
At 245.3 N push / 206.1 N pull at 0.5 MPa, this bore 25 unit suits long, light transfers; for heavier long-stroke work MAJ32 offers 402.2 N at the same pressure, while short light strokes save space with MAJ20 at 157.0 N. The adjuster here is a mechanical end stop alone, so a drifting piston under air loss remains possible - add a suitable valve when holding a position matters. FA flange or LB foot mounting fits the order code, and the G or T suffix converts the 1/8" ports to BSPP or NPT.
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 MAJ25X500-100S FAQ
Stroke is 500 mm, made to order (the standard maximum for bore 25 is 300 mm), with a 100 mm adjustable window trimming extend reach from 500 to 400 mm. Forces: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, about 50 kgf maximum at 1.0 MPa. Rod 10 mm, ports 1/8".
Yes, provided the load is guided externally and side loads stay minimal - the hard-chrome plated 10 mm rod is meant for straight push-pull, not cantilevered bending. The stainless barrel and riveted round body keep the long unit compact and corrosion-resistant, and fixed bumper pads cushion both stroke ends.
