About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-20S
A 300 mm stroke with a 20 mm trim window gives the MAJ32X300-20S a reach you can shorten on site - an external stop screw cuts the extend stroke anywhere inside that window, no cylinder swap needed. Air drives the rod both ways, and at 0.5 MPa the bore 32 piston delivers 402.2 N of push at 30-800 mm/s.
The round stainless barrel with a hard-chrome plated rod shrugs off washdown and damp plant air better than painted minis, while a fixed anti-impact pad softens the hit at each stroke end. Plan real work at roughly 241 N (about 0.6 of the 0.5 MPa push) so the cylinder runs with margin to spare.

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 MAJ32X300-20S Is Used
Carton lane gating
Pushes cartons off the main conveyor into a sortation lane on packaging lines, with the 20 mm trim dialling in the exact divert depth.
Fixture height setting
Sets the drop height of a small assembly fixture on an electronics bench, trimmed per product batch without swapping the cylinder.
Tube-end forming ejector
Acts as the light ejection ram on a tube-end forming station, delivering 402.2 N at 0.5 MPa over the full 300 mm approach.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-20S the Right Cylinder?
Compare before you commit: bore 25 delivers 245.3 N push at 0.5 MPa and bore 40 reaches 628.3 N, so the 32 mm barrel (402.2 N) sits squarely in mid-duty territory. Because the trim screw is a mechanical end stop only, never rely on it to hold a load against drift when air pressure drops - a separate locking method is needed for that.
At 300 mm, guide the tooling or keep side loads off the rod to protect the bushing; FA flange or LB foot mounts plus I and Y rod knuckles cover most fixings, and the standard magnet suits CMSG/DMSG/EMSG switch positioning.
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 MAJ32X300-20S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa the figures rise to 563.0 N push and 483.8 N pull. Theoretical peak output is 82.0 kgf at 1.0 MPa. The rod is 12 mm dia with an M10x1.25 male thread, ports are 1/8", and supply runs 0.15-1.0 MPa (22-145 psi).
No. Every MA-series piston leaves the factory magnetised, so CMSG, DMSG and EMSG reed switches clamp straight onto the 32 mm stainless barrel at any point along the 300 mm stroke - no special-order build required.
