About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X250-100S
Long reach in a round body: the MAJ25X250-100S delivers a 250 mm extend stroke - inside the 300 mm standard range for bore 25 - with a 100 mm stop window, so the same cylinder can be set anywhere from roughly 150 mm to the full 250 mm on the machine. Force output is the classic bore 25 pair: 245 N push, 206 N pull at 0.5 MPa, enough to plan around 147 N of real work or lift about 12 kg vertically at half rating.
The riveted stainless barrel keeps its seal and finish where powder dust and dry-product abrasion would chip a painted mini, and the hard-chrome 10 mm rod resists scoring over that long cantilever. Fixed bumpers absorb the stroke-end knock at full extension; they are not tunable cushions. The magnet is in every unit, so CMSG, DMSG or EMSG sensors drop on for position checks. 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, 1/8" ports.

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 MAJ25X250-100S Is Used
Carton push-off from picking shelves
A full 250 mm sweep clears a shelf-depth carton onto a take-away conveyor, with the 100 mm window tuned per bay depth.
Tray infeed pusher on thermoformer lines
Single-unit flexibility: re-trim the extend stop between tray formats instead of holding spare stroke lengths; about 147 N working force moves loaded trays.
Chute gate on a powder transfer skid
Stainless barrel and 10 mm chrome rod stand up to abrasive dust that scores ordinary minis; a DMSG switch confirms the gate is fully open.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X250-100S the Right Cylinder?
Compare with the 20 mm bore (157 N at 0.5 MPa) for shorter throws or the 32 mm bore (402 N) when the pushed mass grows; both share the MA round-body format. One caution the datasheet will not shout: at 250 mm the rod is a long slender column, so guide the load externally and keep side loads near zero. The trim screw fixes where extension ends but holds nothing - lose air and the piston settles under its own load. Mount FA or LB, fit I or Y knuckles on the rod, order PT thread standard with G or NPT as options.
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 MAJ25X250-100S FAQ
Bore 25 at 0.5 MPa: 245 N push, 206 N pull. At 0.7 MPa: 343 N push, 289 N pull. Theoretical maximum at 1.0 MPa is 50 kgf. The 250 mm stroke stays within the 300 mm standard range for this bore.
Guide the product on its own rail or bushing and let the cylinder push in pure line thrust; the hard-chrome rod is tough, but a long stroke multiplies bending stress. Alignment at mounting - FA flange or LB foot - matters more here than on short-stroke models.
