About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X500-20S
Fine positioning gets easier with the MAJ16X500-20S: after installation, the external stop screw shortens the extend stroke by any amount up to 20 mm, absorbing tolerance stack between the cylinder and its fixture. The action stays fully double acting, with fixed bumper pads calming both ends of the long 500 mm travel.
Force output sits at 100.5 N push and 86.4 N pull at 0.5 MPa; budget around 60 N for real work and expect roughly 5 kg of vertical lift capability at a 2:1 margin. A riveted stainless-steel barrel, hard-chrome plated rod and aluminium covers give the little cylinder a corrosion edge in damp or food-adjacent areas, while the built-in magnet lets CMSG / DMSG / EMSG switches clamp on without a 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 MAJ16X500-20S Is Used
Blister tray seating
A pharma packaging line seats blister trays into a nest, using the 20 mm window to match nest-depth changes between products.
Print head height set
A pad-printing fixture raises and lowers its ink cup, with the stop screw locking the exact contact height after plate changes.
Small-parts chute gate
A machining-cell parts chute gates swarf bins over a 500 mm slide, with CMSG switches confirming the gate is fully open.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X500-20S the Right Cylinder?
Compare before you commit: this bore gives 100.5 N at 0.5 MPa, while MAJ20 (157 N) and MAJ25 (245.3 N) suit heavier small-part jobs. The 20 mm adjuster is an extend-end stop only, so treat it as a positioning reference rather than a brake - the rod is free to move if supply pressure drops. FA flange and LB foot mounts plus I / Y rod knuckles fit most light frames; over a 500 mm stroke, guide the load separately to protect the 6 mm rod from bending.
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 MAJ16X500-20S 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. Maximum theoretical output is 20.5 kgf at 1.0 MPa. Ports are M5x0.8, rod thread M6x1.0, operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
No. Every MAJ carries a standard built-in piston magnet, so CMSG, DMSG or EMSG switches mount straight onto the barrel. Switch positions are set along the 500 mm travel, and the 20 mm extend window can be trimmed afterward without touching the sensing setup.
