About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-30S
The MAJ32X250-30S covers jobs that need a longer trim range: up to 30 mm of the 250 mm extend stroke can be dialed back on the machine with the stop screw. At 0.5 MPa the 32 mm bore swings 402.2 N of push and 345.6 N of pull.
Position sensing is free of paperwork - every MA ships with its magnet already in, so CMSG, DMSG or EMSG switches clip on out of the box. The riveted round body (stainless barrel, rolled aluminium covers) stays slim where profile cylinders would not fit, and after derating, real usable push sits near 241 N at 0.5 MPa.

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 MAJ32X250-30S Is Used
Durability test rig
Cycles a sample or latch 250 mm back and forth on a bench tester; the 30 mm stop window shortens the travel without re-plumbing the circuit.
Tote indexing
Advances totes one station at a time on an accumulation conveyor; a CMSG switch on the standard magnet confirms home before each index.
Case rejector
Knocks mislabeled cases off a packaging lane; 483.8 N of pull at 0.7 MPa retracts the blade under load without stalling.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X250-30S the Right Cylinder?
Between bores: MAJ25X250 pushes 245.3 N at 0.5 MPa and MAJ40X250 reaches 628.3 N, so this 32 mm unit at 402.2 N sits in the middle of the range. Long strokes like 250 mm punish side loading - fixture the load on its own guide rather than hanging it on the 12 mm rod.
The 30 mm window sets where extension stops, but remember the adjuster holds nothing: if supply air fails the rod re-drifts, so use an external latch where a load must stay put. Choose FA flange or LB foot mounting; the magnet is already inside for CMSG / DMSG / EMSG sensing.
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 MAJ32X250-30S FAQ
At 0.5 MPa expect 402.2 N on extend and 345.6 N on retract; at 0.7 MPa the figures become 563.0 N and 483.8 N, and the 32 mm bore tops out at 82.0 kgf theoretical at 1.0 MPa. Derate for real loads - about 241 N of practical push at 0.5 MPa is a sound starting point.
Its barrel is high-precision stainless steel and the 12 mm piston rod is hard-chrome plated to 20 um, so mild corrosion, washdown splash and outdoor exposure cause far less trouble than on painted-steel minis. The aluminium covers are rolled onto the tube, keeping the joint sealed without tie rods.
