About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X120-75S
A wide 75 mm adjustment range separates the MAJ32X120-75S from fixed-stroke minis: turn the external stop screw and the extend stop settles anywhere from the full 120 mm down to 45 mm, all with 402 N of push at 0.5 MPa on tap. Double-acting, 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.
Its riveted round body - stainless tube, aluminium covers, hard-chrome carbon-steel rod - resists corrosion in damp plants without paint to chip. Note that the stop screw is a mechanical end stop, not a brake: if air pressure drops the rod still drifts, so external clamping is needed to secure a load.

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 MAJ32X120-75S Is Used
Sorting chute diverter
The 75 mm window places the extend stop to match three chute widths on a parcel sorter, swapped over in minutes.
Fixture clamp on a machining bench
563 N of push at 0.7 MPa holds aluminium brackets against a drilling jig while the end stop keeps clamp travel repeatable.
Tote stopper gate
Roughly 41 kgf of lift equivalent at 0.5 MPa lets the cylinder pivot a light tote stop up and down on an accumulation conveyor.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X120-75S the Right Cylinder?
Forces place this bore between its neighbours: the 25 mm MAJ gives 245 N at 0.5 MPa, this model 402 N, and the 40 mm MAJ 628 N - so size up only if your load needs more than roughly 240 N of working force. The 75 mm window sets the extend stop anywhere in that band, but treat it purely as a stroke limit, never as a load-holding device during air loss.
FA flange, LB foot, plus I and Y rod knuckles cover the usual mounting cases, and the standard magnet works with CMSG, DMSG and EMSG switches from day one.
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 MAJ32X120-75S FAQ
At 0.5 MPa: 402 N push and 346 N pull. At 0.7 MPa: 563 N push and 484 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. For vertical work, halve the 41 kgf equivalent and you still lift about 20 kg with margin.
No. The stop screw only limits the extend stroke; retract stays at the full 120 mm, and the bumper pads at each end are fixed, not adjustable air cushions. If you need tunable cushioning plus stroke adjustment, the MACJ in the same family is the match.
