About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-75S
With 402 N of push at 0.5 MPa, the MAJ32X250-75S handles gate, ejector and light press duties, and its extend stroke can be dialled back by up to 75 mm using the external stop screw - no shims, no reordering. Double-acting air drives both directions, with 345.6 N on the return at the same pressure.
The riveted round body keeps the footprint tight in crowded frames, while the stainless tube and hard-chrome plated 12 mm rod tolerate damp workshops and rinse-down corners better than painted minis. A magnet is fitted as standard, so CMSG / DMSG / EMSG switches mount straight on for end-of-stroke signals. Matched to real parts, it lifts about 20 kg vertically with a 2:1 margin.

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 MAJ32X250-75S Is Used
Carton lane diverter
At 402 N of push the cylinder drives a diverter arm moving small cartons across a 250 mm gap on a conveyor merge, with the 75 mm trim compensating for new lane spacings.
Tub lid press
Presses snap-on lids onto tubs in a dairy packing cell; the stainless barrel copes with the frequent hose-down that ruins painted bodies.
Cut backstop set
Works as an adjustable backstop on a tube cut-off bench, where the 75 mm window lets operators rezero between stock sizes without parts changes.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-75S the Right Cylinder?
Compare before you commit: the 25 mm bore manages 245 N at 0.5 MPa and the 40 mm bore reaches 628 N, so 32 mm sits mid-pack. Treat the adjuster as a hard end stop, not a mid-travel brake - if air is lost mid-cycle the rod will creep, so fit a locking valve for suspended loads. At 250 mm of travel keep the load guided separately if it overhangs the rod, since side thrust bends thin rods over long strokes. Air enters through 1/8" ports; rod thread is M10x1.25.
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 MAJ32X250-75S FAQ
Measured figures: 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The operating band is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
No. Every MAJ ships with the magnet built in, so CMSG, DMSG or EMSG switches attach directly for end-of-stroke feedback. The stainless barrel and hard-chrome rod also make it a good fit where painted steel minis rust out.
