About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X25-30S
A -30 window on a 25 mm stroke means the stop screw can dial the extend length anywhere from nearly zero to the full 25 mm - the ordered stroke stays the ceiling and the screw only shortens it. Double-acting and reversible, this 16 mm bore makes 100.5 N forward and 86.4 N return at 0.5 MPa, or 140.7 / 120.9 N when run at 0.7 MPa.
The round stainless barrel with its hard-chrome rod is a practical pick for wet or dusty machine corners where painted aluminium minis corrode. Air enters through M5x0.8 ports at 0.15-1.0 MPa (22-145 psi), rod speed 30-800 mm/s, and a fixed anti-impact pad quiets the stroke end without acting as an adjustable cushion. After a standard margin, treat roughly 60 N as the force you can actually put to work at 0.5 MPa.

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 MAJ16X25-30S Is Used
Reject pusher on narrow conveyors
Kicks undersized caps off a slim conveyor lane; the trim screw sets exactly how far the 6 mm rod reaches in.
Stamp alignment pin
Sets pin height on a badge-stamping fixture, adjusting per die with light seating force at 0.5 MPa.
Escapement gate
Gates one component at a time from a bowl-feeder track, with an EMSG switch verifying the gate-open position.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X25-30S the Right Cylinder?
Size up if needed: bore 20 gives 157 N at 0.5 MPa against this model's 100.5 N, and bore 16 is already the floor of the MA range. Treat the adjuster as a position-setting end stop for extend only - it will not hold a load against air loss, so add a check or external lock where that matters. FA flange or LB foot mounting, I / Y knuckles on the 6 mm rod, and the standard magnet reads through CMSG / DMSG / EMSG switches.
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 MAJ16X25-30S FAQ
Count on 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and a 20.5 kgf theoretical ceiling at 1.0 MPa. Stroke 25 mm, adjustable window -30, ports M5x0.8, rod 6 mm with M6x1.0 thread, speed 30-800 mm/s.
No - the pad is a fixed anti-impact bumper that decelerates the rod at stroke end; adjustable air cushioning belongs to the MAC family. What this model does carry is the standard built-in magnet for CMSG / DMSG / EMSG switches plus a stainless riveted body that shrugs off washdown splashes.
