About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-40S
One stop screw changes everything here: the MAJ32X300-40S extends up to 300 mm but can be trimmed anywhere within a 40 mm window once bolted into the machine. Both strokes are air-driven (double-acting), with bore 32 output of 402.2 N push and 345.6 N pull at 0.5 MPa.
A riveted round-body build - stainless barrel, chrome-plated carbon rod, aluminium covers - stays compact in tight machine envelopes. Treat 241 N (60% of the 0.5 MPa push rating) as the practical working force and the actuator will outlast marginal-duty sizing.

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 MAJ32X300-40S Is Used
Weld fixture clamping
Clamps brackets against a welding jig, with the 40 mm window absorbing jig-to-jig setup differences on the fixture line.
Tote divert pusher
Pushes totes between roller conveyor lanes in a warehouse, where the 300 mm reach clears the lane edge without fouling.
Press-fit locator
Positions housings ahead of a small press-fit operation, the extend stroke trimmed to the exact locating depth.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-40S the Right Cylinder?
Bore 25 tops out at 245.3 N and bore 40 starts at 628.3 N (both at 0.5 MPa); the 32 mm MAJ splits the difference at 402.2 N push. Remember the stop screw only trims the extend stroke and holds position solely while air is on - it is not a lock for hanging loads.
With 300 mm of travel, bending moments grow fast: support the tooling on its own guides rather than leaning on the rod. FA and LB mounts plus the standard magnet for switch triggers round out the package.
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 MAJ32X300-40S FAQ
At 0.5 MPa: 402.2 N extend, 345.6 N retract. At 0.7 MPa: 563.0 N extend, 483.8 N retract. Ceiling is 82.0 kgf theoretical at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) against an operating band of 0.15-1.0 MPa (22-145 psi).
The round barrel is stainless steel, the covers are aluminium alloy and the 12 mm rod is hard-chrome plated to about 20 um, so damp plant air, splashes and periodic washdown cause far less trouble than on painted mini cylinders. The port on this bore is 1/8".
