About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X45-50S
One cylinder, several product sizes: a shop-floor stop screw dials the extend stroke anywhere inside the 50 mm window of this MAJ25X45-50S, so changeovers need no hardware swap. Double-acting drive, a roll-packed stainless barrel with aluminium covers, a hard-chrome plated 10 mm rod and a standard magnet for CMSG / DMSG / EMSG sensing complete the picture.
Force output is 245.3 N forward and 206.1 N reverse at 0.5 MPa, climbing to 343.4 N and 288.5 N at 0.7 MPa with a 50 kgf theoretical ceiling. Size the task to about 147 N at 0.5 MPa - the load this bore moves all day with margin - and note the trim screw stops the rod but cannot arrest it if air pressure is lost. Operating envelope: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, -20 to +70 C.

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 MAJ25X45-50S Is Used
Carton-height gate
Sets a diverting gate for two carton heights on a packing line; the 50 mm window covers both settings, swapped by the external screw between runs.
Dispense-depth stop
Trims the plunge depth of a glue or filler head between SKUs; 245.3 N push keeps the head seated through its full 45 mm cycle.
Tote stopper
Stops a tote at a manual pick station on a roller conveyor; 206.1 N pull retracts the stop clear, and the stainless body shrugs off cool-room humidity.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X45-50S the Right Cylinder?
Neighbouring bores frame the choice: 20 mm gives 157 N and 40 mm gives 628.3 N, both at 0.5 MPa, so pick the 25 mm when the real load - friction included - lands between them. Because the stop screw is a hard stop and not a brake, an unsupported load will still drift the rod if pressure fails. LB feet bolt the body to fixture plates, FA flanges line the bore up with the load, and I or Y knuckles connect linkages; at 45 mm stroke, rod bending is rarely a concern if side load is kept low.
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 MAJ25X45-50S FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. The -50 suffix is the extend-stroke trim window, adjustable on the machine with the external stop screw; fixed bumper pads cushion both stroke ends and speed spans 30-800 mm/s.
The riveted stainless round body and hard-chrome plated rod resist mild corrosion and tolerate occasional washdown, an edge over painted-steel mini cylinders in food or outdoor duty. For tunable deceleration instead of fixed bumpers, move up to the MACJ version.
