Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 250mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S
Adjustability is the headline: the MACJ16X250-30S runs a 250 mm double-acting stroke that the external stop screw can shorten by up to 30 mm on site, with a variable air cushion at both ends to soak up end-of-stroke shock. The piston magnet comes as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel. At 0.5 MPa this bore 16 unit pushes 100.5 N and pulls 86.4 N.
Its rolled stainless round barrel pairs with a hard-chrome plated 6 mm rod, standing up to washdown and damp corners that ruin painted minis. Count on roughly 60 N of usable push at 0.5 MPa, enough to lift about 5 kg vertically, across a 0.15-1.0 MPa (22-145 psi) supply and 30-800 mm/s speed range.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S Is Used
Reject pusher
Nudges misaligned bottle caps off a bottling line conveyor; the 30 mm window tunes the push distance without swapping cylinders.
Sample presenter
Slides vial trays into a lab analyzer read head, with the standard magnet and a CMSG switch confirming home position each cycle.
Carton flap tuck
Folds light card flaps on a small-box packing station, cushioned ends so the flap is creased but never crushed.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S the Right Cylinder?
Bore 16 is the smallest in the MA family; if 100.5 N at 0.5 MPa leaves too little headroom, step up to the 20 mm bore (157.0 N) or 25 mm bore (245.3 N). Keep in mind the stop screw only sets the extend position - it is not a load-holding brake, so the rod will drift if air pressure is lost. Mount with an FA flange or LB foot and add an I or Y knuckle where the load swivels; over 250 mm of travel, guide the load and keep side forces low to protect the slim 6 mm rod.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-30S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa that rises to 140.7 N on extend. Theoretical maximum at 1.0 MPa is about 20.5 kgf. Run it on 0.15-1.0 MPa (22-145 psi) of 40 um filtered air at 30-800 mm/s.
Yes. The round barrel is stainless steel with a hard-chrome plated carbon-steel rod, a combination that resists the rust and flaking paint painted minis suffer in washdown or outdoor spots. Air ports are M5x0.8, suiting compact manifold blocks.
