About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-75S
A double-acting round-body mini cylinder built on a riveted stainless-steel barrel, the MAJ25X300-75S delivers 245.3 N of push at 0.5 MPa across a 300 mm stroke, with an external stop screw that trims the extend stroke by up to 75 mm on site. Supply air at 0.15-1.0 MPa (22-145 psi) and run rod speeds from 30 to 800 mm/s.
The hard-chrome plated 10 mm rod and grease-retaining two-way piston seal keep friction stable over long travels, while fixed anti-impact pads soften both stroke ends. Because the magnet ships standard, CMSG, DMSG or EMSG switches clip on without special ordering. At 0.5 MPa the rated 245.3 N push supports roughly 147 N of real work once you keep a 40 percent reserve.

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 MAJ25X300-75S Is Used
Bakery tray diverter
Pushes tray carriers off a cooling conveyor at 245 N; trim the 300 mm throw to 225 mm so trays land squarely on the packing table.
Washdown gate latch
Stainless barrel and chrome rod shrug off daily hose-down in a dairy bottling hall where painted mini bodies corrode.
Carton pusher
The stop screw lets one cylinder serve several carton widths, and bumper pads quiet each stroke end at up to 800 mm/s.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X300-75S the Right Cylinder?
For lighter duty the 20 mm bore gives 157.0 N push at 0.5 MPa; step up to the 32 mm bore for 402.2 N. Keep in mind the stop screw is a mechanical end stop only: with air off, the piston still drifts, so support the load externally. FA flange or LB foot mounting plus I and Y rod knuckles suit gate and pusher linkages, and the 1/8" port with M10x1.25 male rod thread makes plumbing straightforward.
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 MAJ25X300-75S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa those figures rise to 343.4 N push and 288.5 N pull. Theoretical maximum is 50.0 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi).
Yes - a magnet is built into every MAJ piston as standard, so AirTAC CMSG, DMSG and EMSG switches mount straight onto the stainless barrel. Note that the stop screw only sets the extend end position; it is not a brake, so the rod can drift if supply air is removed under load.
