About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X20-10S
Cramped fixtures often need less than 30 mm of travel, and this 16 mm bore cylinder delivers exactly that with a 10 mm trim window for fine-tuning the extend position on site. It is double-acting - air extends and retracts - producing 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N at 0.7 MPa.
The barrel is stainless steel with covers riveted on, so there are no tie-rods to check and no paint to chip in damp cells; the 6 mm rod is hard-chrome plated to 20 um. A magnet is fitted as standard, letting CMSG / DMSG / EMSG switches report position with no extra order. Working numbers: plan on roughly 60 N of push at 0.5 MPa for the job, enough to seat small inserts or hoist near 5 kg straight up with a 2:1 cushion. Fixed bumpers quiet both ends of the short 20 mm stroke, and the trim stop positions but does not lock anything in place if air is lost.

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 MAJ16X20-10S Is Used
Pin pusher in PCB routing fixtures
Ejects locating pins over a 20 mm travel, with the 10 mm trim letting technicians zero the rest position against each pallet.
Presence probe on a gauge station
Advances a probe tip to touch-check small machined parts; a CMSG switch on the standard magnet flags the forward detent.
Tab fold on a benchtop cartoner
Folds small carton flaps with about 60 N of practical push at 0.5 MPa, sized for the light cardstock of pilot packaging runs.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X20-10S the Right Cylinder?
Nothing in the MAJ line is smaller than this 16 mm bore, so if 100.5 N of push at 0.5 MPa leaves margin too thin, step to the 20 mm bore and its 157 N. Because the travel is only 20 mm, side-load worry is far lower than on long-stroke versions, though external guiding still pays off on precision work. FA flange, LB foot or I / Y knuckles cover mounting; the magnet for CMSG / DMSG / EMSG sensing is already inside. For the same compact size with adjustable air cushioning, see MACJ; for a rod at both ends, MAD.
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 MAJ16X20-10S FAQ
Push 100.5 N and pull 86.4 N at 0.5 MPa; push 140.7 N and pull 120.9 N at 0.7 MPa; theoretical maximum about 20.5 kgf at 1.0 MPa. Speed range is 30-800 mm/s and pressure 0.15-1.0 MPa (22-145 psi). The air port is M5x0.8 and the 6 mm rod thread is M6x1.0.
The rolled stainless tube and hard-chrome 6 mm rod resist splash and humidity without coatings, an advantage over painted minis in food-adjacent or outdoor cells. The magnet comes standard for CMSG / DMSG / EMSG switches, and fixed bumper pads cushion the 20 mm stroke - just remember the 10 mm trim stop sets position only and never holds a load on its own.
