About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-50S
Bore 40 mm, stroke 160 mm and a 50 mm on-site trim window: the MAJ40X160-50S is AirTAC's double-acting MAJ mini cylinder with an adjustable extend stroke. Set by an external stop screw, the window shortens the extend stroke only; it never lengthens it past the ordered 160 mm. At 0.5 MPa the piston pushes 628 N and pulls 528 N, rising to 880 N push at 0.7 MPa (working 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa = 215 psi). Keep real work near 377 N at 0.5 MPa so this bore stays comfortably inside its envelope.
The riveted round body pairs a stainless-steel barrel with a hard-chrome 16 mm rod (20 um plating), shrugging off mild corrosion and washdown where painted minis fail. The fixed anti-impact pad softens stroke-end landing but is not an adjustable cushion. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches clamp on without a special-order piston. Runs 30-800 mm/s on air filtered to 40 um, -20 to +70 C.

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 MAJ40X160-50S Is Used
Lift-gate ejection on packaging machines
A 50 mm trim lets setup teams dial the eject stroke to the carton height; about 32 kg vertical lift with a 2:1 margin covers loaded trays.
Pusher arms on washdown conveyor lines
The stainless barrel tolerates wet, rinsed-down frames better than painted minis, while 628 N pushes heavy totes off the belt.
Stop-and-sort gates on assembly cells
Retracting at 528 N pull, the cylinder repositions gate plates quickly at speeds up to 800 mm/s with endpoint feedback from a fitted DMSG switch.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-50S the Right Cylinder?
Choose the 32 mm bore (402 N push at 0.5 MPa) if roughly 240 N of working force covers the job; 40 mm is already the largest MAJ bore, so stepping up means moving to a different series. The adjuster is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the rod still drifts, so add a locking valve if position must hold. Mount with the FA flange or LB foot, add an I or Y rod knuckle (no SDB option on the adjustable build). At 160 mm of stroke on a 16 mm rod, guide the load externally if any side force is present.
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 MAJ40X160-50S FAQ
At 0.5 MPa the 40 mm bore pushes 628.3 N and pulls 527.8 N double-acting; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull. Theoretical maximum force is 128.1 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
An external stop screw trims the extend stroke anywhere within the ordered 50 mm window - it shortens the stroke, never extends it. The fixed bumper pad softens the landing at the set position, and the built-in magnet (standard) lets CMSG / DMSG / EMSG switches flag the trimmed endpoint.
