About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X125-100S
A 100 mm trim range makes the MAJ16X125-100S unusually flexible for a Dia 16 mini: the stop screw sets the extend stroke from 25 mm all the way to the full 125 mm, in service, by hand. Double-acting air power delivers 100.5 N of push and 86.4 N of pull at 0.5 MPa, with fixed bumper pads taking the sting out of stroke ends.
For sizing, count on about 60 N of real work at 0.5 MPa - roughly a 5 kg vertical lift with a 2:1 margin. The riveted stainless barrel and hard-chrome carbon-steel rod shrug off splash and humidity, a genuine advantage over painted-aluminium minis in food or outdoor cells. Every unit ships with a standard magnet, so adding CMSG / DMSG / EMSG switches needs no special-order piston.

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 MAJ16X125-100S Is Used
Carton flap tucker on a case packer
Folds small end flaps on 150 mm cosmetic cartons; the 25-125 mm stroke range covers tall and short cartons without changing the cylinder.
Light lid lift on a filling bench
Raises a hinged acrylic guard or dosing lid weighing under 1 kg; about 5 kg of vertical capability at a 2:1 margin leaves room for hinge friction.
Stopper pin on an assembly rotary table
Halts small fixtures between stations; the stop screw pins the exact extend position when the table pitch changes between product variants.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X125-100S the Right Cylinder?
Compare before you commit: there is no smaller MA bore (16 mm is the floor), while a 20 mm bore makes 157 N and a 25 mm bore makes 245.3 N of push at 0.5 MPa. If your part weighs near 10 kg, the bigger bore is the safer call.
The 100 mm window means one cylinder can cover many stroke settings on a changeover line. Foot (LB) or flange (FA) mounting plus I / Y knuckles are the mounting choices here - no SDB on adjustable models. The adjuster is an extend-end stop, not a brake; with air off, the piston can still move. Long 125 mm travel on a 6 mm rod calls for a guide rail whenever side forces appear.
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 MAJ16X125-100S FAQ
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push (120.9 N pull) at 0.7 MPa. At the theoretical maximum of 1.0 MPa the bore reaches about 20.5 kgf. Run it anywhere from 0.15 to 1.0 MPa (22-145 psi) at 30-800 mm/s.
The external stop screw shortens the extend stroke within the ordered 100 mm window - here from 25 up to 125 mm. It is a mechanical end stop that sets the extend position; it does not hold the load mid-stroke, and if air pressure is lost the piston can still drift. Fixed anti-impact bumper pads cushion the ends of travel.
