About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-40S
Trim the extend stroke on site with a screwdriver: the MAJ32X80-40S carries a 40 mm adjustable window over its 80 mm base stroke, set by an external stop. The 32 mm bore pushes 402.2 N and pulls 345.6 N at 0.5 MPa, rising to 563.0 N and 483.8 N at 0.7 MPa.
Fixed anti-impact pads soften both stroke ends - they decelerate the piston but are not the adjustable air cushions found on the MAC family. In practical terms the bore translates to about 41 kgf of vertical lift at 0.5 MPa, so with a 2:1 margin it hoists roughly 20 kg - enough for loaded small-parts trays or plastic lids. The magnet is built in as standard for CMSG, DMSG and EMSG switches.

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 MAJ32X80-40S Is Used
Flap tuck station
Tucking bottom flaps on a secondary carton sealer: the 40 mm window lets one cylinder handle two carton heights by simply resetting the stop screw.
Vial tray lifter
Raising a rack of 20 ml vials into a capping head - the halved lift capacity of about 20 kg vertical covers the tray and product with margin.
Reject gate actuator
Kicking off-spec blister packs aside at an inspection station; CMSG switches on the standard magnet confirm both extend and retract.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-40S the Right Cylinder?
Size both directions: a 25 mm bore gives 245.3 N at 0.5 MPa, this model 402.2 N, and stepping to 40 mm buys 628.3 N. Loads under roughly 145 N suit the smaller frame, while anything beyond about 377 N of real demand should move up a bore.
The 40 mm stop screw shortens extend travel only - it cannot push the stroke past 80 mm and it never pins the piston mid-stroke if air fails. Choose FA or LB mounting, G or NPT threads where needed, and rely on the standard magnet for CMSG, DMSG or 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 MAJ32X80-40S FAQ
Run it anywhere from 0.15-1.0 MPa (22-145 psi). At 0.5 MPa the extend force is 402.2 N and retract 345.6 N; at 0.7 MPa expect 563.0 N and 483.8 N. Theoretical peak output of the 32 mm bore is 82 kgf at 1.0 MPa, and rod speed spans 30-800 mm/s with 1.5 MPa (215 psi) proof pressure.
Yes. The barrel is stainless steel and the 12 mm carbon-steel rod carries a 20 um hard-chrome plating, a combination that handles washdown and humidity far better than painted mini cylinders. Aluminium-alloy covers are rolled onto the tube for a sealed, riveted body.
