About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-75S
Line-down cleaning is where painted minis fail, but this MAJ keeps a stainless round barrel and a hard-chrome plated 10 mm rod in service through daily hose-downs. It is double-acting, and the external stop screw pulls the extend stroke back up to 75 mm from the ordered 225 mm, so a single part covers several station depths. At 0.5 MPa the 25 mm bore makes 245.3 N forward and 343.4 N at 0.7 MPa, within a 0.15-1.0 MPa (22-145 psi) operating range.
For sizing, treat roughly 147 N as the practical output at 0.5 MPa, which is about a 12 kg vertical lift at a 2:1 margin. The piston magnet is standard equipment, so CMSG and DMSG switches report end positions from day one, and the riveted covers keep the overall body short in crowded frames.

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 MAJ25X225-75S Is Used
Bottle rinsing stopper gate
Stops PET bottles ahead of the rinse tunnel; the stainless barrel survives caustic washdown twice a shift.
Tote divert on picking line
Deflects totes between pick lanes; 245 N at 0.5 MPa handles loaded 20 kg totes with margin to spare.
Depth-set test press
Presses connectors into a fixture for go/no-go checks; the 75 mm trim tunes travel per connector height.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X225-75S the Right Cylinder?
A bore 20 cylinder returns 157 N at 0.5 MPa and a bore 32 returns 402 N, so this 25 mm bore sits squarely in the middle duty band. If the load must hold against gravity, remember the trim screw fixes travel length but does not clamp the piston; air loss lets it drift, so add a locking valve where that matters. Choose the FA flange for face mounting or the LB foot for base frames, with I or Y knuckles available on the rod side. On a 225 mm stroke, side loads are the main rod-killer: guide the payload separately rather than cantilevering it off the chrome rod.
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 MAJ25X225-75S FAQ
Double-acting 25 mm bore: 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, 50 kgf theoretical maximum at 1.0 MPa. Rod 10 mm on an M10x1.25 thread, 1/8" ports, 0.15-1.0 MPa (22-145 psi) working pressure, 30-800 mm/s speed range, extend stroke trimmable across the 75 mm window.
The barrel is stainless steel and the rod is hard-chrome plated carbon steel at 20 um, so humidity, splash and daily hose-downs do not flake paint or pit the working surface the way they do on painted mini cylinders. Aluminium-alloy covers are riveted on, leaving no external fasteners along the barrel to corrode.
