About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-20S
A short-stroke actuator with a twist: the MAJ32X25-20S pairs a 32 mm bore with a 25 mm stroke and an external stop screw that trims the extend stroke by up to 20 mm on site, so one cylinder covers several end positions. Double-acting air drives both directions, and the magnet is built in as standard, so CMSG, DMSG or EMSG switches snap straight onto the stainless barrel without a special-order piston.
At 0.5 MPa the bore delivers 402.2 N of push and 345.6 N of pull; keep real work near 241 N and the cylinder holds a comfortable margin. For vertical jobs it hoists about 41 kg at full 0.5 MPa output, or 20 kg with a 2:1 margin. The riveted round body - stainless barrel, hard-chrome plated rod, aluminium covers - shrugs off washdown and damp better than painted minis, and the fixed bumper pad softens stroke-end impact without needing an air cushion.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAJ32X25-20S Is Used
Jig clamp on a drill press
The 20 mm trim window lets one MAJ32X25-20S clamp drill-jig blocks of slightly different heights with 402 N of push at 0.5 MPa.
Ejector for small moldings
Short 25 mm travel suits kicking finished connectors or caps out of a fixture nest at up to 800 mm/s.
Lane diverter at a packaging infeed
Stainless barrel and hard-chrome rod tolerate frequent wipe-downs around food-grade conveying lanes.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X25-20S the Right Cylinder?
Needing less force? The 25 mm bore MAJ gives 245.3 N push at 0.5 MPa; needing more, step to the 40 mm bore for 628.3 N. This 20 mm trim window suits repeatable short positioning where the workpiece varies a few millimetres. FA flange, LB foot and I / Y rod knuckles cover mounting; the stop screw sets the extend limit only - it is not a mid-stroke lock, so the rod can drift if air is lost.
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 MAJ32X25-20S FAQ
At 0.5 MPa: 402.2 N push and 345.6 N pull. At 0.7 MPa: 563.0 N push and 483.8 N pull. Theoretical maximum at 1.0 MPa is 82 kgf. Air supply range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s.
Yes - the magnet is fitted as standard on every MA-series piston, so AirTAC CMSG, DMSG and EMSG switches clip onto the stainless barrel with no special-order piston or factory wait.
