About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X40-40S
With a 40 mm trim window on a 40 mm stroke, the MAJ16X40-40S lets you dial the extend travel from nearly zero to full without swapping the cylinder. Bore is 16 mm, pushing 100.5 N and pulling 86.4 N at 0.5 MPa - that translates to lifting about 5 kg vertically once you keep a 2:1 margin. Port is M5x0.8 and the rod is 6 mm.
The body is a rolled stainless tube with aluminium end covers, so washdown mist and shop-floor humidity do not chew through a coating the way they do on painted minis. A fixed anti-impact pad eases the piston into each end of travel - damping only, not an adjustable cushion. The magnet is built in as standard, so CMSG / DMSG / EMSG switches mount straight onto the 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 MAJ16X40-40S Is Used
Probe lifter on a PCB test fixture
Set the exact lift height for each fixture revision with the 40 mm window; 100.5 N clears populated boards weighing well under 5 kg.
Stamp marker on a date-coder
Air at 0.7 MPa gives 140.7 N, enough to leave a clean ink stamp on cartons while the bumper pads quiet the strike.
Syringe plunger press in a small filler
The stainless barrel wipes down after media changes, and the 86.4 N pull retracts the plunger for the next fill.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X40-40S the Right Cylinder?
Choose this over a fixed-stroke MA16 when you need to fine-tune reach on the machine; if 100.5 N at 0.5 MPa feels light, the 20 mm bore delivers 157.0 N. Bear in mind the stop screw only sets an end position and will not hold a load against air loss. LB foot or FA flange mounting, with I and Y knuckles on the M6x1.0 rod thread.
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 MAJ16X40-40S FAQ
Push is 100.5 N and pull is 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N and 120.9 N. Maximum theoretical output is 20.5 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
Yes - the -40 window covers the entire 40 mm stroke, so the external stop screw can trim extend travel to almost any fraction. It is an end stop, not a load lock: with air removed the rod still moves. The built-in magnet is standard and pairs with CMSG, DMSG or EMSG switches.
