About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X180-10S
Long reach and fine trimming meet in the MAJ40X180-10S, a double-acting 40 mm mini cylinder whose extend stroke can be dialed down 10 mm with an external stop screw. Force output is the strongest in the MA series: 628.3 N push and 527.8 N pull at 0.5 MPa, rising to 879.6 N push at 0.7 MPa, with 128.1 kgf theoretical at 1.0 MPa. In practice that means it lifts about 32 kg vertically even with a 2:1 safety margin factored in.
The riveted round barrel is stainless steel, matched to a hard-chrome plated rod, so spray, condensation and outdoor weather cause far less trouble than on painted mini cylinders. Every unit leaves the factory with a built-in magnet, so position sensing with CMSG, DMSG or EMSG switches needs no special-order piston, and fixed bumper pads take the sting out of stroke ends. Supply 0.15-1.0 MPa (22-145 psi); speed 30-800 mm/s.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAJ40X180-10S Is Used
Reject gate on a snack-food checkweigher
Pushes off-spec packs off the belt with 628 N to spare at 0.5 MPa, while the stainless body copes with daily hose-down hygiene routines.
Drawbar lock on a CNC pallet changer
The 10 mm trim window lets commissioning engineers dial in exact seating of the drawbar pin without shimming the bracket.
Case stop on a sortation conveyor
Stops cartons with force equivalent to lifting about 32 kg vertically, position fed back through a DMSG switch on the standard magnet.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X180-10S the Right Cylinder?
Bore 40 already sits at the top of the MA range, so step down to the MAJ32 (402.2 N push / 345.6 N pull at 0.5 MPa) when the duty is light rather than oversizing on force. The 10 mm trim window suits a fixed end-of-travel target that may need a few millimetres of on-site correction, such as seating a part against a gauge. FA flange and LB foot mounts are available, with I or Y knuckles for swivelling tooling. Over a 180 mm stroke, keep the 16 mm rod free of side load or support the load on external guides.
The stop screw fixes the extend end position only; it will not hold the piston against a lost air supply and it is not a brake. For tunable cushioning at stroke ends rather than fixed bumpers, compare the MACJ variant.
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 MAJ40X180-10S FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa. At 0.7 MPa push is 879.6 N and pull 738.9 N. Theoretical maximum is 128.1 kgf at 1.0 MPa. Ports on this 40 mm bore are 1/8", rod 16 mm with an M12x1.25 male thread.
No. The magnet is standard equipment in every MA-series cylinder, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel without a special piston or waiting for a custom build.
