About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X180-30S
Only 30 mm of this 180 mm stroke is adjustable - the external stop screw trims extend travel down to 150 mm when the fixture changes, no cylinder swap needed. Double-acting bore 25 output measures 245.3 N push and 206.1 N pull at 0.5 MPa, climbing to 343.4 N at 0.7 MPa, with fixed bumper pads taking the sting out of each stroke end.
The round stainless barrel and rolled aluminium covers keep the body compact and corrosion-resistant; the hard-chromed carbon-steel rod holds up in humid workshops where painted minis pit. AirTAC fits the magnet in every MA cylinder as standard, so position feedback with CMSG, DMSG or EMSG switches costs nothing extra. Rule of thumb: count on about 147 N of practical force at 0.5 MPa, enough to lift roughly 12 kg vertically once you keep a 2:1 margin.

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 MAJ25X180-30S Is Used
Vial tray handling
Lab automation lifting a 12 kg tray of vials vertically is comfortable at half the 245.3 N push rating, and the 30 mm window lets the Z-axis park just above the conveyor.
Product diverter
Pushing cartons across a 180 mm conveyor gap takes well under the 147 N practical force at 0.5 MPa, while the stop screw keeps the pusher retracted to a repeatable home.
Hopper gate dosing
A slide gate on a small powder hopper opens and closes against light pellet pressure; 245.3 N push at 0.5 MPa and the fixed bumper pads keep cycles quiet at full speed.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X180-30S the Right Cylinder?
Compare before you buy: the MAJ20 tops out at 157.0 N push at 0.5 MPa while the MAJ32 reaches 402.2 N, so this 245.3 N bore 25 covers the middle ground for medium clamps and pushers. Remember the adjuster shortens extend travel only and never locks position - on air loss the rod still drifts. FA flange or LB foot mounting, I/Y rod knuckles optional, 1/8" ports, 0.15-1.0 MPa (22-145 psi) supply, 30-800 mm/s. At 180 mm extension, keep buckling and side thrust off the rod with external guides.
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 MAJ25X180-30S FAQ
Bore 25 gives 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, and 50 kgf theoretical max at 1.0 MPa. Practically, keep work load near 147 N; vertically that lifts about 12 kg with a 2:1 margin. Supply 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, 1/8" ports.
They are fixed anti-impact pads that decelerate the piston at each stroke end; they are not adjustable air cushions. If your cycle needs tunable cushioning, look at the AirTAC MACJ family instead, which combines cushioning with the adjustable stroke.
