About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X225-10S
With a 40 mm bore turning 0.5 MPa air into 628 N of push, the MAJ40X225-10S is AirTAC's double-acting round-body mini cylinder with an adjustable extend stroke: an external stop screw trims the extend position anywhere inside a 10 mm window without swapping cylinders. The 225 mm stroke is a standard length for this bore, whose standard strokes reach 500 mm, and the piston rod is 16 mm hard-chrome-plated steel.
Build quality is where this unit earns its keep. The high-precision stainless barrel is riveted to aluminium-alloy covers, so mild corrosion and washdown spray are non-issues, and the fixed anti-impact pad at each stroke end softens deceleration (it is a bumper, not an adjustable air cushion). Every MAJ ships with a magnet built in, ready for CMSG / DMSG / EMSG switches. For real work at 0.5 MPa, budget roughly 377 N - about 32 kg lifted vertically with a 2:1 margin - rather than the full 628 N rating.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X225-10S Is Used
Canning line four-pack pusher
Slides filled 330 ml craft-beer cans sideways into four-pack clips on a brewery conveyor, with the 10 mm window retuned whenever clip tooling height changes.
Die-cast part eject assist
Knocks small aluminium encoder housings off their cores after a trim press cycle, where a firm 628 N bump clears sticky flash from the cavity.
Case flap pre-fold
Pre-folds the minor flaps of corrugated shipper cases ahead of a tape head, holding a consistent crease height across several carton sizes.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X225-10S the Right Cylinder?
Size down to a 32 mm MA (402.2 N push at 0.5 MPa) when the load is under about 240 N; this 40 mm bore gives 628.3 N of push and 527.8 N of pull at 0.5 MPa, or 879.6 N pushing at 0.7 MPa. It runs on 0.15-1.0 MPa (22-145 psi) of filtered air and travels 30-800 mm/s. Remember the stop screw is a mechanical end stop for the extend stroke only - with air lost the rod will drift back, so it is not a mid-stroke lock or a load-holding brake. At 225 mm of stroke, keep side loads off the 16 mm rod and guide the workpiece externally if the mass sits off-axis. FA flange or LB foot mounting, with I and Y rod knuckles available; the magnet is standard, so position sensing via CMSG / DMSG / EMSG switches needs no special piston.
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 MAJ40X225-10S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull. The theoretical maximum at 1.0 MPa is about 128.1 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and rod speed 30-800 mm/s. The port is 1/8" and the rod thread is M12x1.25.
No. The external stop screw sets the extend position anywhere inside the 10 mm window; the fixed anti-impact pads at each end simply soften the landing. Adjustable cushioning belongs to the MACJ family. The built-in magnet, standard on every MA cylinder, accepts CMSG / DMSG / EMSG switches with no special-order piston.
