About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X75-20S
Shorten the extend stroke by up to 20 mm without touching the air side: on the MAJ16X75-20S an external stop screw sets the forward limit inside its ordered window, and double-acting ports keep the 6 mm rod powered out and back. Rated 100.5 N out and 86.4 N in at 0.5 MPa, or 140.7 N out at 0.7 MPa, across a 0.15-1.0 MPa (22-145 psi) band and 30-800 mm/s speeds.
Where coolant mist or outdoor damp kills painted mini cylinders, the stainless barrel and 20 um hard-chrome plating keep moving. A magnet ships in every piston, so position feedback via CMSG, DMSG or EMSG switches costs nothing extra. In practice allow about 60 N of the rated thrust for the work itself - enough to lift near 5 kg vertically at a 2:1 ratio.

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 MAJ16X75-20S Is Used
Oven door latch on a curing line
Pulls a spring latch to release a small powder-curing oven door at cycle end, staying reliable where heat-soaked painted hardware would fail.
Punch pilot in a stamping die
Advances a pilot pin 75 mm into strip stock to locate the web before the punch descends, with the 20 mm window trimming for thinner blanks.
Turntable gate pusher
Swings a light gate open at a paint-booth turntable exit as parts rotate off the fixture, sized to the roughly 60 N the bore really delivers.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X75-20S the Right Cylinder?
Compare both directions before ordering: nothing smaller exists than the 16 mm bore, while MAJ20 doubles the thrust to 157.0 N and MAJ40 reaches 628.3 N at 0.5 MPa. The 20 mm trim window works only downward - it shortens the extend stroke, never lengthens it past 75 mm. Do not rely on the stop screw to park a load when air fails; it is a position stop, not a brake, so clamp externally where needed. Pick FA flange or LB foot, mate an I or Y knuckle to the rod thread (M6x1.0), and the built-in magnet accepts CMSG, DMSG or EMSG switches as 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 MAJ16X75-20S FAQ
At 0.5 MPa: 100.5 N extend, 86.4 N retract. At 0.7 MPa: 140.7 N extend, 120.9 N retract. The 1.0 MPa theoretical maximum for the bore is 20.5 kgf. Pressure may run 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
Ports are M5x0.8 (a function of the 16 mm bore), the rod thread is M6x1.0, and thread variants come in PT, G and NPT. Mount via FA flange or LB foot, add an I or Y rod knuckle, and the standard-fit magnet accepts CMSG, DMSG and EMSG switches. Stroke trimming is done by the external stop screw within the 20 mm window.
