About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-30S
Double-acting and stroke-adjustable, the MAJ25X50-30S takes bore 25 force - 245.3 N push at 0.5 MPa - and lets an external stop screw cut the extend stroke by up to 30 mm on site. Plan on roughly 147 N of that rating for effective work, enough to clamp small brackets or kick parts off a light conveyor fixture.
The riveted stainless round barrel with its hard-chrome plated 20 um rod shrugs off splash and mild washdown, a real edge over painted-steel minis in damp corners of a plant. Fixed anti-impact pads soften the stroke ends (deceleration only - adjustable cushioning is the MAC family's job), and the magnet is built in as standard, so CMSG, DMSG or EMSG switches mount without a special-order piston.

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 MAJ25X50-30S Is Used
Fixture clamping
Trim the extend stroke to match fixture depth on a small assembly press, adjusting per part without swapping cylinders or re-plumbing.
Part ejection
A practical push of about 147 N clears small machined caps off a conveyor lane, with speed set anywhere from 30 to 800 mm/s.
Carton kickers
Diverts small cartons on packaging lines; the stainless barrel tolerates periodic washdown near food-handling zones.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X50-30S the Right Cylinder?
At 245.3 N push / 206.1 N pull at 0.5 MPa, bore 25 sits between the MAJ20 (157.0 N push) and the MAJ32 (402.2 N push), so check the load first and step up if friction eats the margin. The 30 mm adjuster is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the rod still drifts, so do not lean on it to hold a load. FA flange and LB foot mountings plus I and Y rod knuckles cover most fixes; order the G or T suffix for BSPP or NPT threads on the 1/8" ports.
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 MAJ25X50-30S FAQ
At 0.5 MPa the bore 25 piston pushes 245.3 N and pulls 206.1 N; at 0.7 MPa push rises to 343.4 N. Theoretical maximum is about 50 kgf at 1.0 MPa. The rod is 10 mm, ports are 1/8", rod thread M10x1.25, pressure 0.15-1.0 MPa (22-145 psi).
No. The magnet comes built in as standard, so AirTAC CMSG, DMSG and EMSG switches clip onto the barrel directly. Running window is 30-800 mm/s, and the fixed bumper pads damp impact at both stroke ends.
