About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X350-20S
With a 20 mm trimming band on the extend stroke, this 16 mm bore double-acting cylinder lets one unit serve several product heights - just turn the stop screw. Rated output is 100.5 N push and 86.4 N pull at 0.5 MPa, with 140.7 N available at 0.7 MPa.
Vertically, the 100.5 N push is worth roughly 10 kgf at face value, so with a 2:1 margin it lifts about 5 kg - a good match for small jigs and caps. The stainless barrel and chrome-plated rod handle humid or lightly washed areas, and the built-in magnet takes CMSG, DMSG or EMSG switches straight from stock.

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 MAJ16X350-20S Is Used
Tray height changeover
On a snack-tray packing line, the 20 mm window covers two tray heights without re-drilling brackets; 100.5 N at 0.5 MPa seats each tray softly onto its nest.
Glue bead follower
Keep a dispensing nose at a set height above moving boards; the stop screw trims the drop in seconds during product changeovers on a woodworking bench.
Small-parts press
A bench fixture that presses dowel pins into wooden knobs, using about 60 N of working force at 0.5 MPa for a safe margin below the 100.5 N rating.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X350-20S the Right Cylinder?
Compare across the range: the 20 mm bore gives 157 N push at 0.5 MPa and the 32 mm bore 402.2 N if you later need more muscle. Note the 350 mm stroke exceeds the 300 mm standard for bore 16, so it is produced to order; keep the 6 mm rod side-load free with an external guide. Mount with an FA flange or LB foot, and remember the screw stop holds position only while air is present - it never locks the load mid-stroke.
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 MAJ16X350-20S FAQ
For the MAJ16X350-20S: 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 theoretical maximum of 20.5 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-800 mm/s.
No. Every MAJ ships with the magnet already fitted - no special piston is ordered. Snap a CMSG, DMSG or EMSG switch onto the stainless barrel and you have end-of-stroke signals in both directions.
