About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-50S
Position four different stop points from one cylinder: the MAJ16X400-50S carries a 50 mm adjustable extend window on its 400 mm stroke, trimmed via an external stop screw. Output at this bore is modest - 100.5 N push and 86.4 N pull at 0.5 MPa - so it suits gates, chutes and small index fixtures rather than heavy clamping. The 400 mm stroke is a custom build, since the catalogue maximum for 16 mm bores is 300 mm.
Bumper pads at each end take the sting out of stroke-end contact, though they are fixed, not adjustable cushions. If you need to hoist, halve the rating for safety and expect it to raise roughly 5 kg of dead weight vertically. Feed it 0.15-1.0 MPa (22-145 psi) for 30-800 mm/s travel, and use the built-in standard magnet with a CMSG or DMSG switch for position feedback along the stainless barrel.

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 MAJ16X400-50S Is Used
Stamping die part blowout
Ejecting finished terminals from a press die nest; about 60 N of usable force at 0.5 MPa clears the part without marking the plating.
Roaster chute gate
Opening a gravity gate to drop roasted beans between hoppers; the 50 mm window sets a partial-open position for throttling the flow.
Tray presence check
Poking a feeler into empty electronics tray pockets to catch missing connectors before reflow, with an EMSG switch logging each cycle.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-50S the Right Cylinder?
A 400 mm stroke on a 6 mm rod demands clean alignment: mount with FA flange or LB foot hardware and guide the load externally rather than letting it side-load the rod. If 100.5 N at 0.5 MPa is marginal, the next sizes up are bore 20 (157 N) and bore 25 (245.3 N). The 50 mm window covers most re-gripping tweaks, and because the stop is a mechanical end stop only, add an external catcher if the load must be held against air loss.
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 MAJ16X400-50S FAQ
Count on 100.5 N push and 86.4 N pull at 0.5 MPa, climbing to 140.7 N push and 120.9 N pull at 0.7 MPa, with 20.5 kgf the theoretical maximum at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) and speed range 30-800 mm/s.
FA flange and LB foot mounts, plus I or Y rod knuckles on the 6 mm male M6x1.0 rod thread; the SDB double-rod option does not apply to the adjustable version. Place the flange or feet to support the long 400 mm barrel against sag and keep the rod free of side loads.
