About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-40S
Need a 175 mm reach with stroke trimming? The MAJ25X175-40S shortens its extend stroke by up to 40 mm through an external stop screw - a mechanical end stop, not a mid-stroke lock, so on air loss the rod still drifts. Push force is 245.3 N at 0.5 MPa, with about 50 kgf as the theoretical peak.
The hard-chrome rod (20 um plate over carbon steel) slides in a riveted stainless barrel that resists washdown mist far better than painted minis. Every unit carries the magnet as standard; mounting choices are FA flange or LB foot, plus I and Y rod knuckles for pivoting links.

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 MAJ25X175-40S Is Used
Battery clamp verify
Presses a battery pack onto its charge contacts in AGV charging bays, the 40 mm window matching pack heights.
Vial cap press
Seats caps on 30 ml vials in a pharma line where the stainless barrel survives frequent wipe-downs.
Machine setup stop
Acts as an adjustable hard stop for a changeover slide, trimmed at the machine rather than in the storeroom.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-40S the Right Cylinder?
If 245.3 N at 0.5 MPa is marginal for your jig, bore 32 reaches 402.2 N; if it is generous, bore 20 at 157.0 N costs less air. Mount via FA flange for face tooling or LB foot for base-mounted lines. Do not treat the stop screw as a load lock - it only trims travel, and the piston can still creep if pressure drops.
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 MAJ25X175-40S FAQ
Double-acting bore 25 numbers: 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; roughly 50 kgf theoretical at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi).
The stainless-steel barrel is rolled tight to the aluminium-alloy covers, shrugging off washdown mist and outdoor damp that pit painted minis. Inside, a 20 um hard-chrome plate on the carbon-steel rod cuts wear, and fixed bumper pads soften the ends of travel.
