About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X225-40S
The 40 mm window on this MAJ lets one cylinder serve several product sizes: set the extend stop once per changeover within the ordered range, and the 16 mm bore does the rest with 100.5 N of push at 0.5 MPa, 86.4 N of pull, and 140.7 N at 0.7 MPa (20.5 kgf theoretical at full pressure).
Inside is the familiar MA recipe: a riveted stainless round barrel, aluminium-alloy covers, and a hard-chrome plated carbon-steel rod that outlasts painted minis in humid plants. The piston magnet comes as standard for CMSG, DMSG or EMSG reed switching, with no special-order piston required. Budget roughly 60 N - six-tenths of the 0.5 MPa rating - for the actual working load, which also equals lifting about 5 kg vertically with a 2:1 margin.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X225-40S Is Used
Pick-light flag pusher
Taps a pick indicator flag on warehouse flow racks; the 40 mm window covers different shelf depths without changing the cylinder.
Small-part elevator
Lifts roughly 5 kg class fixtures vertically between assembly benches, using the 100.5 N push at 0.5 MPa with margin to spare.
Semi-finished-part stopper
Stops aluminium extrusion offcuts on a roller table; the stainless round body survives cutting-fluid mist that rusts painted minis.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X225-40S the Right Cylinder?
Among MA bores this is the smallest force class; if 100.5 N at 0.5 MPa is marginal, the 20 mm bore next up delivers 157.0 N under the same pressure. At 225 mm of travel the 6 mm rod is slender, so support or guide the load externally and avoid side loading to protect the rod and bushing.
The stop sets the end of extension only - it is not a brake, and a cylinder that loses air will not hold position by itself, so fit a separate clamp where loads must stay put. Speed is tunable across 30-800 mm/s, temperature spans -20 to +70 C, and the port on this bore is M5x0.8 with an M6x1.0 male rod thread.
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 MAJ16X225-40S FAQ
Moderately: push climbs from 100.5 N at 0.5 MPa to 140.7 N at 0.7 MPa (pull goes from 86.4 N to 120.9 N), topping out at a 20.5 kgf theoretical maximum at 1.0 MPa. Above 0.7 MPa, margin shrinks fast, so for heavier jobs step up a bore rather than pressure - proof pressure is 1.5 MPa (215 psi).
The barrel is stainless steel and the 6 mm carbon-steel rod carries a 20 um hard-chrome plate, so the cylinder tolerates washdown splash, cutting-fluid mist and outdoor humidity better than painted-steel or bare-aluminium minis. The covers are aluminium alloy, rolled onto the barrel for a sealed, compact body.
