About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X55-30S
Need fine end positioning in a compact envelope? The MAJ16X55-30S gives Dia 16 double-acting force with a 30 mm field-adjustable extend window: turn the stop screw, not the whole machine. Output is 100.5 N push at 0.5 MPa (140.7 N at 0.7), and speed spans 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply.
Rivet-rolled aluminium covers and a stainless block seal a stainless-steel barrel around a hard-chrome plated rod, giving a slim round body that shrugs off damp shop air. A fixed bumper pad eases the stroke-end impact without acting as an adjustable cushion, and the standard-built magnet accepts CMSG, DMSG or EMSG switches for position feedback.

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 MAJ16X55-30S Is Used
Small jig clamp on CNC fixtures
Clamps a machined blank against a fixed stop with about 60 N of usable force; re-trim the 30 mm window when the fixture is re-tooled.
Sensor arm retraction on checkweighers
Pulls a thickness-sensing arm clear of passing packs; the built-in magnet and CMSG switch give a verified retract signal.
Sorter flap diversion
Flicks a lightweight diverter flap between two chutes on a packaging line; 86.4 N pull force at 0.5 MPa returns the flap against spring tension.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X55-30S the Right Cylinder?
Compare before you commit: this Dia 16 gives 100.5 N push / 86.4 N pull at 0.5 MPa, while a Dia 20 MAJ reaches 157.0 N - the step up is cheap insurance for heavier caps or jigs. The 30 mm trim range fits machines whose final stop is tuned on the commissioning floor. The adjuster is a mechanical end stop, not a mid-stroke brake, so an unpowered piston will still coast - plan external holding where drift matters. Choose FA flange or LB foot mounting, I or Y knuckles as needed; ports are M5x0.8 with an M6x1.0 rod thread.
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 MAJ16X55-30S FAQ
Push is 100.5 N and pull is 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N push and 120.9 N pull, peaking at 20.5 kgf theoretical at 1.0 MPa. Stroke is 55 mm with a 30 mm adjustable extend window, supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s. The Dia 16 bore uses M5x0.8 ports and an M6x1.0 male rod thread.
The barrel is stainless steel and the rod is hard-chrome plated to 20 um, so washdown splash and humid air cause far less trouble than on painted-steel mini cylinders. Covers are aluminium alloy riveted onto the barrel, keeping the round body slim for tight machine layouts.
