About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X80-75S
With its 75 mm adjustable window, the MAJ25X80-75S lets a technician dial the extend stroke from 80 mm down over most of its travel using nothing more than the external stop screw. The bore 25 piston delivers 245 N push and 206 N pull at 0.5 MPa across a 0.15-1.0 MPa (22-145 psi) supply. Its round stainless barrel is rolled onto aluminium-alloy covers in a compact riveted build, and the hard-chrome plated carbon-steel rod shrugs off the corrosion painted minis pick up in damp shops.
Size the job around 147 N - about 60 percent of the 245 N push rating - and you keep a healthy reserve; that is enough muscle to lift a 12 kg fixture vertically with margin, since this bore could theoretically hoist 25 kg at 0.5 MPa. The built-in magnet pairs with CMSG or EMSG switches for position checks along the trimmed stroke.

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 MAJ25X80-75S Is Used
Carton stop on a packing conveyor
Stops cartons at the case-packer infeed, with the 75 mm window letting operators shorten the throw for small cartons without swapping the cylinder.
Ejector on an injection-mould fixture
Kicks cooled parts out of a shallow mould; 343 N of push at 0.7 MPa clears sticky offcuts quickly between cycles.
Index-pin retractor
Pulls a locating pin from a rotary index table; 206 N of pull at 0.5 MPa retracts reliably amid coolant mist.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X80-75S the Right Cylinder?
Between bores: the 20 mm MAJ pushes 157 N at 0.5 MPa and the 32 mm version 402 N, so bore 25 sits in the middle for medium jigs and gates. The stop screw only shortens extension and cannot clamp a load mid-stroke - on air loss the piston drifts - so support heavy loads mechanically. FA flange and LB foot mounts cover fixed frames; I and Y knuckles suit pivoting links.
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 MAJ25X80-75S FAQ
No. Every MAJ ships with the piston magnet already fitted, so CMSG, DMSG and EMSG switches mount on the stainless barrel out of the box - handy for confirming the trimmed extend position set by the stop screw. The air connection is a 1/8 inch port and the male rod thread is M10x1.25.
The MAJ25X80-75S generates 245 N push and 206 N pull at 0.5 MPa, and 343 N push with 289 N pull at 0.7 MPa. Theoretical peak force is 50 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
