About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X80-10S
The MAJ25X80-10S is a compact double-acting round-body mini cylinder from AirTAC with a 10 mm adjustable extend window: an external stop screw lets you shorten the 80 mm stroke by up to 10 mm without ordering a new part. At 0.5 MPa it pushes 245.3 N, a dependable output for grippers, clamp blocks and small press heads in tight spaces.
Its stainless barrel and hard-chrome plated 10 mm rod shrug off washdown and mild corrosion better than painted minis, and the built-in magnet means CMSG, DMSG or EMSG switches mount with no special order. In practice, size around 147 N of real work at 0.5 MPa - a two-to-one margin - or expect it to lift roughly 12 kg vertically with that same headroom.

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 MAJ25X80-10S Is Used
Carton flap tuck station
Tucks the end flaps on a snack-carton line; the 10 mm window dials the tuck depth to each carton blank without changing parts.
Sample vial stoppering
A benchtop stopper press seats caps on 16 mm vials; 245 N of push is ample for the rubber plug interference fit.
PCB fixture clamp
Holds edge fixtures down inside an in-circuit test rig, where the short trimmed stroke keeps the clamp clear of probe fields.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X80-10S the Right Cylinder?
At 0.5 MPa the 25 mm bore delivers 245.3 N of push; if the load is lighter, an MAJ20X80 (157 N) saves space, while heavier clamping calls for an MAJ32X80 (402.2 N). Remember the stop screw is an extend-side end stop only - it never holds the load if air pressure drops, so use a valve or a separate lock for safe holding. Mount it FA flange or LB foot; I and Y rod knuckles cover the swing links, and the magnet is fitted as standard.
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 MAJ25X80-10S FAQ
At 0.5 MPa: 245.3 N push and 206.1 N pull. At 0.7 MPa: 343.4 N push and 288.5 N pull. The theoretical ceiling is 50 kgf at 1.0 MPa. Air supply should be filtered to 40 um within 0.15-1.0 MPa (22-145 psi), and rod speed runs 30-800 mm/s.
No. Every MAJ ships with the magnet built in, so CMSG, DMSG and EMSG switches clip straight onto the 25 mm stainless barrel for end-of-stroke detection - no special-order piston and no waiting.
