About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-75S
With the widest trim in the range, the MAJ32X80-75S shortens its 80 mm extend stroke anywhere inside a 75 mm window - down to a 5 mm effective push if the fixture needs it. Force output is unchanged: 402.2 N extend and 345.6 N retract at 0.5 MPa, peaking at 563.0 N at 0.7 MPa.
A stainless round barrel and a hard-chrome 12 mm rod tolerate alcohol wipe-downs and humid food-plant air, an edge painted mini cylinders lack. The external stop is a mechanical end stop only - on air loss the piston can still drift, so never treat it as a load-holding brake. With a 2:1 margin the bore lifts about 20 kg vertically, matching small trays and covers.

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 MAJ32X80-75S Is Used
Multi-height stop gate
One cylinder, many products: the 75 mm window sets stop gates for three different bottle heights on the same filling line fixture.
Tray lane pusher
Feeding trays one lane deeper in a storage carousel - retract stays at 80 mm while the extend stroke is trimmed to the exact lane depth.
Sample slide elevator
Lifting microscope sample slides into a camera station, where the stainless barrel stands up to weekly alcohol wipe-downs in the lab.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-75S the Right Cylinder?
Fit the force band first: 245.3 N from a 25 mm bore, 402.2 N from this 32 mm unit, 628.3 N from a 40 mm bore - all at 0.5 MPa. The 75 mm window is the widest trim offered in the -NN range, handy when one cylinder must serve several product heights on the same fixture.
Retraction always runs the full 80 mm; only the extend stroke is trimmed. The stop is an end-of-travel setting, not a holding brake, so secure gravity loads by other means on air loss. Mount with an FA flange or LB foot, add I or Y knuckles if the tool needs float, and clip a CMSG, DMSG or EMSG switch to the barrel for position signals.
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 MAJ32X80-75S FAQ
At 0.5 MPa: 402.2 N on extend, 345.6 N on retract. At 0.7 MPa: 563.0 N and 483.8 N. Maximum theoretical output for the bore is 82 kgf at 1.0 MPa. Piston speed range is 30-800 mm/s and supply pressure 0.15-1.0 MPa (22-145 psi), with 1.5 MPa (215 psi) proof pressure.
No. The fixed bumper pad at each stroke end simply decelerates the piston to soften impact; it is not an adjustable pneumatic cushion, which is a feature of the MACJ family instead. Also remember the stop screw sets end of travel - it is not a mid-stroke lock, and the rod can drift if air is lost.
