About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X200-20S
Where tooling changes shift the stop point by a few centimeters, the MAJ25X200-20S answers with a 20 mm extend-stroke window on a 200 mm cylinder. Expect 245.3 N of push at 0.5 MPa and 343.4 N at 0.7 MPa; derate to about 147 N for continuous work or count on lifting near 12 kg vertically with margin.
Build quality starts with a stainless barrel rolled onto aluminium covers - no tie rods to loosen, and the compact round body slots into tight machine frames. Mild washdown is no problem; the hard-chrome rod surface resists corrosion and sliding wear. The magnet comes standard, letting CMSG, DMSG or EMSG switches flag end positions from day one.

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 MAJ25X200-20S Is Used
Label head press trim
Presses labels onto bottles at a washdown filling station; the 20 mm window absorbs container height variation between changeovers.
Sorter diverter flap
Kicks small parcels onto an offload belt where 245.3 N of push swings the flap quickly across the main line.
Bin eject on a pick module
Pushes plastic totes out of a shelf lane into an operator tray; the stop screw matches different tote depths without new brackets.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X200-20S the Right Cylinder?
Size by force: the 20 mm bore delivers 157 N at 0.5 MPa, this 25 mm bore 245.3 N, and the 32 mm bore 402.2 N, so one step is usually enough. Supply air at 0.15-1.0 MPa (22-145 psi) and keep rod speed in the 30-800 mm/s band. Treat the trim screw as an endpoint setter only; mid-stroke, the piston is free to move if pressure drops.
FA flange and LB foot mounts suit fixed frames, while I and Y knuckles handle swinging loads. With 200 mm of stroke, brace any side load externally so the 10 mm rod stays in compression.
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.
