About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-75S
With a 400 mm travel and a 75 mm on-site trim window, the MAJ16X400-75S is AirTAC's long-stroke entry in the 16 mm bore class: a double-acting round-body mini cylinder whose extend stroke you dial down with an external stop screw anywhere inside that 75 mm range. At 0.5 MPa it pushes 100.5 N and pulls 86.4 N, rising to 140.7 N push at 0.7 MPa.
The stainless barrel and hard-chrome plated 6 mm rod shrug off washdown spray and damp workshop air far better than painted-steel minis, and the riveted aluminium covers keep the body slim. Budget roughly 60 N - about six tenths of the 100.5 N rating - for real work at 0.5 MPa; vertically that is close to lifting a 5 kg part with a 2:1 margin. A magnet ships built in, so CMSG, DMSG or EMSG switches clip on without special ordering.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X400-75S Is Used
Long conveyor gating
Swing or lift a gate across a wide conveyor line; 100.5 N is ample for a light aluminium gate and the 75 mm window absorbs belt-width variations.
Lab sample elevator
Raise sample trays between shelves in analytical equipment - vertical duty near the 5 kg lift mark, with magnet switches confirming top position.
Carton eject at end of line
Push light empty cartons off a packaging outfeed; fixed bumper pads soften each stroke end at the 30-800 mm/s speed the line runs.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-75S the Right Cylinder?
Need more muscle? The next bore up, 20 mm, pushes 157.0 N at 0.5 MPa versus 100.5 N here; there is no smaller MA bore. At 400 mm travel keep side loads off the 6 mm rod - guide the load externally or the rod will bend. The stop screw trims the extend stroke only; it is not a brake, and the piston will still drift if air is lost. Foot (LB) or flange (FA) mounting, plus the standard magnet covering CMSG / DMSG / EMSG switches, round out the package.
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 MAJ16X400-75S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N. The theoretical ceiling at 1.0 MPa is 20.5 kgf. Ports are M5x0.8 and the male rod thread is M6x1.0.
The S only confirms the magnet, which is standard on every MA cylinder anyway - CMSG, DMSG and EMSG switches mount directly. The stainless barrel plus hard-chrome 6 mm rod also suit damp or lightly washed-down areas; run it on 40 um filtered air at 0.15-1.0 MPa (22-145 psi).
