About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-50S
Half the battle with small cylinders is mounting space; the riveted round body of the MAJ16X120-50S keeps a low profile while the stainless barrel and 6 mm hard-chrome rod stand up to damp, dusty or outdoor conditions that ruin painted minis. Double-acting air drives both strokes, and an external stop screw trims the extend travel anywhere within a 50 mm window of the ordered 120 mm.
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa; sized for steady work that is roughly 60 N of real push force per cycle. Speed range is 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply, and the standard magnet lets CMSG / DMSG / EMSG switches report position with no special-order piston.

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 MAJ16X120-50S Is Used
Bin pick feed
In a small-parts store the cylinder nudges bins forward to the pick face while a DMSG switch on the built-in magnet confirms each nudge; 100.5 N at 0.5 MPa slides loaded bins along a rail.
Machine height dial-in
Retrofit stations gain a 50 mm tuning range, letting one cylinder serve three product heights without shimming; about 60 N of working push handles light clamps.
Sleeve neck guiding
Guides shrink-sleeve necks on bottleneck lines; the stainless barrel shrugs off condensation near the steam tunnel and M5x0.8 ports keep the tubing tidy.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-50S the Right Cylinder?
This bore tops out at a theoretical 20.5 kgf, so for heavier jobs move to the 20 mm MAJ with 157 N push at 0.5 MPa - or pair two 16 mm cylinders side by side to double the force on wide parts. The 50 mm window is the widest extend trim in this group, useful when one machine runs several product heights. Mount by FA flange or LB foot, fit I or Y knuckles for pivoting loads, and remember the screw only fixes the extend end point - it is not a holding brake if supply air drops.
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 MAJ16X120-50S FAQ
At 0.5 MPa: 100.5 N push, 86.4 N pull. At 0.7 MPa: 140.7 N push, 120.9 N pull. Theoretical maximum at 1.0 MPa: 20.5 kgf for this 16 mm bore. Those numbers assume 40 um filtered air, a 0.15-1.0 MPa (22-145 psi) supply and 30-800 mm/s speed.
A high-precision stainless tube is rolled together with aluminium-alloy covers and a stainless block, forming a sealed round body of compact length. The 6 mm carbon-steel rod carries a 20 um hard-chrome plating, so mild corrosion and outdoor damp cause little trouble, and the stop screw adds up to 50 mm of on-site extend trim.
