About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-30S
A 30 mm trim window makes this 16 mm bore mini cylinder a fit for stations where the extend length must be dialled in on site - the external stop screw shortens the 120 mm stroke but never lengthens travel past the ordered value. Air works both ways (double-acting), the barrel is stainless steel rolled onto aluminium covers, and the rod is 6 mm carbon steel with a 20 um hard-chrome face.
Rated 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push at 0.7 MPa. For vertical lifts, 100.5 N is about 10 kg of raw lift - set the job at roughly 5 kg and you keep a 2:1 margin. Running speed is 30-800 mm/s over a 0.15-1.0 MPa (22-145 psi) supply, and the standard magnet pairs with CMSG / DMSG / EMSG switches straight out of the box.

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 MAJ16X120-30S Is Used
Micro press depth set
A dial-table micro press seats terminals at two depths thanks to the 30 mm window; about 60 N of usable push keeps light crimps safe from over-force.
Carton tab folding
Folds small carton tabs on a packaging line; the stainless barrel tolerates wipe-downs near food-grade zones and a CMSG sensor on the built-in magnet counts each fold.
Label head height set
Lowers a labelling head onto flat pouches; trimming 30 mm off the extend stroke lets one cylinder serve two pouch formats without shims.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-30S the Right Cylinder?
If 100.5 N at 0.5 MPa undershoots the load, the next bore up (20 mm) offers 157 N push - the 16 mm is the entry size, so nothing smaller exists in the MAJ line. Keep in mind the stop screw sets an end-of-stroke position, not a brake: when supply air drops, the piston still drifts. Foot (LB) and flange (FA) mounts plus I or Y knuckles suit tight frames, and the M5x0.8 ports keep the plumbing compact.
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 MAJ16X120-30S FAQ
Key numbers: 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push at 0.7 MPa, and a theoretical 20.5 kgf maximum at 1.0 MPa for the 16 mm bore. Supply clean air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and cycle anywhere from 30-800 mm/s.
No. Fixed anti-impact pads take the sharpness off the stroke end, but they decelerate only - an adjustable air cushion belongs to the MAC family, not this model. The screw sets where the extend stroke ends inside your 30 mm window; it is not a mid-stroke lock and the rod can move if air is lost.
