About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X15-20S
Short-stroke AirTAC MAJ work: bore 32, 15 mm of travel, and an external stop screw that trims the extend stroke within the 20 mm window ordered with the code. Double-acting throughout, it pushes 402.2 N and pulls 345.6 N at 0.5 MPa (supply 0.15-1.0 MPa (22-145 psi), air filtered to 40 um), climbing to 563.0 N at 0.7 MPa.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated 12 mm rod, so mild corrosion and washdown splash are non-events where painted-steel minis fail. The 402.2 N rating is a ceiling: keep real continuous work near 241 N at 0.5 MPa and the seals last. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches mount straight on.

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 MAJ32X15-20S Is Used
Small-part ejection
Kicks finished brass fittings off a deburring bench at 30-800 mm/s, with the 20 mm window letting operators dial in the exact kick distance.
Micro clamp fixture
Holds thin aluminium sheets against a drill jig; the 241 N working figure leaves real margin on the 402.2 N rating.
Rotary index trigger
Fires the unlock pin on a 4-station dial table, with CMSG switches confirming home position through the standard magnet.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X15-20S the Right Cylinder?
At 402.2 N push at 0.5 MPa this bore 32 sits between the MAJ25 (245.3 N) and the MAJ40 (628.3 N); step down if your clamps need under 245 N, up if over 400. The stop screw sets the end of the extend stroke only - it is a mechanical limit, not a brake, so the rod still drifts if air is lost. Choose FA flange or LB foot mounting, add an I or Y rod knuckle where the load hinges, and rely on the standard magnet with CMSG / DMSG / EMSG switches for position signals.
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 MAJ32X15-20S FAQ
Double-acting with a 15 mm stroke and a 20 mm adjustable extend window: push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Ports are 1/8", rod thread M10x1.25, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The MAJ carries fixed anti-impact bumper pads that soften end-of-stroke contact; they decelerate only and are not adjustable cushions - for that, look at the MACJ family. On a 15 mm stroke piston energy is low, so the pads are usually sufficient.
