About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X125-40S
Need a light-duty cylinder whose extend stroke you can dial in after installation? The MAJ16X125-40S gives a 16 mm bore, 125 mm stroke and a 40 mm trim window on the extend side, set by an external stop screw. Push force is 100.5 N at 0.5 MPa (86.4 N on retract), with air at 0.15-1.0 MPa (22-145 psi) and speeds from 30 to 800 mm/s.
Fixed anti-impact bumper pads soften the stroke ends; they decelerate only and are not an adjustable air cushion, which is what the MACJ family provides. The riveted stainless round body with its hard-chrome 6 mm rod suits splash zones and outdoor panels. Count on about 60 N of working push at 0.5 MPa, or a vertical lift of roughly 5 kg with a 2:1 margin.

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 MAJ16X125-40S Is Used
Lab fixture clamp
Holds small polycarbonate covers on a laboratory test rig; 100.5 N at 0.5 MPa is gentle enough not to crack the parts.
Hopper micro-gate
Feather-opens a gate under a seed hopper, with the trim window set so pellets meter out at the same spot every cycle.
Carton flag trigger
Pushes a flag arm that triggers the date coder on a small carton line; the magnet picks up a CMSG switch for cycle confirmation.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X125-40S the Right Cylinder?
Compare by force first: at 0.5 MPa the 20 mm bore gives 157.0 N and the 25 mm bore 245.3 N, so step up if your load needs more than about 60 N at this size. Connection is M5x0.8 with an M6x1.0 male rod thread. Choose FA flange or LB foot mounting, plus I or Y knuckles on the rod. The 40 mm window trims the extend stroke; it is not a mid-stroke lock, and with air lost the rod can drift, so support loads mechanically.
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 MAJ16X125-40S FAQ
At 0.5 MPa: 100.5 N push and 86.4 N pull. At 0.7 MPa: 140.7 N push and 120.9 N pull. The maximum theoretical force at 1.0 MPa is 20.5 kgf.
No. The MAJ carries fixed anti-impact bumper pads that only soften the impact. If you need adjustable air cushioning, look at the AirTAC MACJ family; for a double rod, the MAD covers that job.
