About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-30S
For long-push stations that need fine travel control, this MAJ32X300-30S pairs a 300 mm stroke with a 30 mm adjustable window: turn the external stop screw and the extend stroke lands exactly where the fixture wants it. Double-acting power on both strokes puts 402.2 N on the work at 0.5 MPa.
Every MA-series body ships with a built-in magnet, so CMSG, DMSG or EMSG reed switches mount straight onto the riveted stainless barrel without a special-order piston. Dividing the 402.2 N push by gravity gives about 41 kg of theoretical vertical lift - keep it near 20 kg on real lift-off duty for a 2:1 margin.

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 MAJ32X300-30S Is Used
Dial-table part ejection
Ejects finished parts from rotary-index fixtures at the unload station, where the 30 mm window matches varying part heights.
Sample tray indexing
Advances sample trays one slot at a time in a laboratory autosampler build, with the stroke adjusted to the tray pitch.
Tray fill depth stop
Sets the fill depth on a tray-loading head in a bakery packaging line, shortening the extend stroke as recipes change.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-30S the Right Cylinder?
If 245.3 N from a bore 25 unit falls short but a bore 40 cylinder at 628.3 N is oversized, this 32 mm model's 402.2 N at 0.5 MPa is the middle path. The adjustable stop shortens the extend stroke only - it lengthens nothing and it does not clamp the piston mid-travel, so an unpowered rod can still be shifted by hand or by the load itself.
Long 300 mm strokes amplify side loads, so couple it with external linear guides for cantilevered tooling. Choose FA flange, LB foot, or the I/Y knuckles; magnetic position sensing comes built in.
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 MAJ32X300-30S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa expect 563.0 N push and 483.8 N pull. Theoretical maximum is 82.0 kgf at 1.0 MPa. Rod speed runs 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) air supply, with a 12 mm rod threaded M10x1.25.
Fixed anti-impact bumper pads are moulded into both covers and soak up the piston's arrival at each end. They decelerate only - unlike the cushioned MACJ family there is no needle valve to tune - so bring fast-moving external loads to rest with speed controls.
