About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-10S
For long, light-duty positioning the MAJ16X400-10S pairs an order-made 400 mm stroke (the 16 mm bore normally stops at 300 mm) with a 10 mm fine-trim stop screw for last-millimetre setup. Expect 100.5 N forward and 86.4 N retract at 0.5 MPa, which is about a 5 kg vertical lift at half rating. Air connections are M5x0.8 ports on both covers.
Build quality is where this model earns its keep: a stainless barrel rolled onto aluminium covers, a 20 um hard-chrome plate on the 6 mm rod, and a grease-retaining two-way piston seal that keeps friction low over 400 mm of travel. Bumper pads are fixed, damping end-of-stroke shock without acting as an adjustable cushion. Magnets ship standard for CMSG / DMSG / EMSG sensing.

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 MAJ16X400-10S Is Used
Height-setting probe on a gauge station
The 10 mm trim dials in exact probe contact; 100.5 N at 0.5 MPa is ample for a 300 g sensor head.
Label applicator sweep on a case line
400 mm covers the full case width, and the stainless barrel handles damp cold-room air without coating flake.
Fine-part ejector on a watch-parts press
M5x0.8 plumbing suits the compact manifold, and the 86.4 N return clears tiny components quickly.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X400-10S the Right Cylinder?
At this stroke and force class the load must be guided - the 6 mm rod is meant for push-pull of light fixtures, not side-loaded tooling. If 100.5 N at 0.5 MPa is marginal, the 20 mm bore (157.0 N) adds headroom. The 10 mm window makes final stroke adjustment a set-and-forget job; note the stop is no holding brake and the rod moves under air loss. FA or LB mounting, I / Y knuckles available.
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 MAJ16X400-10S FAQ
Push 100.5 N and pull 86.4 N at 0.5 MPa; 140.7 N and 120.9 N at 0.7 MPa; 20.5 kgf theoretical maximum at 1.0 MPa. Pressure range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, port M5x0.8.
A 10 mm window is for final calibration once the machine is built - you keep the full 400 mm stroke and shave only the last fraction for exact part seating. The stop screw is a mechanical end stop, so expect rod drift if air is lost. CMSG, DMSG and EMSG switches fit thanks to the standard magnet.
