About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-20S
Inside a riveted stainless round barrel, this 16 mm bore mini cylinder runs double-acting and lets you trim the extend stroke up to 20 mm with an external stop screw - handy when two product sizes share one station. Ports are M5x0.8, the rod is 6 mm hard-chrome steel, and the magnet that ships built in accepts CMSG, DMSG or EMSG switches without a special-order piston.
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push reaches 140.7 N. For steady cycling, budget roughly 60 N of real push at 0.5 MPa - that margin is the difference between a jerky stall and a smooth stroke. The fixed anti-impact pad softens the landing at stroke end; it decelerates only, while an adjustable cushion is a MAC family feature.

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 MAJ16X120-20S Is Used
Vial stopper seating
A benchtop press for 2 ml vials needs only about 60 N of working push; the 20 mm trim window lets one cylinder serve two vial heights.
Small-part kick-off
Kicks connectors or caps off a narrow conveyor lane; the 100.5 N push at 0.5 MPa handles light plastic parts and the 120 mm stroke crosses the lane.
Switched gate latch
CMSG or EMSG switches clip onto the built-in magnet to confirm open and closed on a small enclosure door, with no special-order piston needed.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-20S the Right Cylinder?
This is the smallest bore in the MAJ range, so step up to the 20 mm bore (157 N push at 0.5 MPa) if 100.5 N feels tight for the job. The adjuster acts as a mechanical end stop for extension only - with air lost the rod can still drift, so never treat it as a load lock. Mount with an FA flange or LB foot, add I or Y rod knuckles if the load pivots, and order G or NPT ports when PT does not match your plant standard.
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 MAJ16X120-20S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push rises to 140.7 N. Theoretical maximum at 1.0 MPa is 20.5 kgf for this 16 mm bore. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The stainless barrel paired with a hard-chrome plated 6 mm rod shrugs off washdown splash and mild corrosion far better than painted-steel minis, and the riveted covers keep the footprint slim. FA flange and LB foot plates plus I and Y knuckles cover most small-machine fixings.
