Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 25mm 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 MACJ16X25-30S
Compact yet capable, the MACJ16X25-30S pairs a 16 mm stainless barrel with a 25 mm stroke whose extend length can be trimmed on site within a 30 mm window via the external stop screw. Double acting throughout, it pushes 100.5 N and pulls 86.4 N at 0.5 MPa, rising to 140.7 N at 0.7 MPa, while variable air cushions at both ends soak up end-of-stroke shock so light tooling can cycle at speed without hammering the covers.
The riveted round body keeps a hard-chrome plated 6 mm rod sliding inside a stainless tube, a build that shrugs off washdown and damp shop air where painted minis rust. In practice, size around 60 N of working push at 0.5 MPa rather than the full rating, and remember the built-in magnet means CMSG, DMSG or EMSG switches clip straight on. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s.

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 MACJ16X25-30S Is Used
Fixture presence check
A short 25 mm probe stroke with a 30 mm trim window lets a jig builder set exact probing depth on an aluminium die-cast fixture, with a DMSG switch confirming contact.
Carton flap tuck
At 100.5 N push the cylinder tucks small flaps on a bakery carton line, and cushioning at both caps keeps rapid cycling quiet at the end of each throw.
Lab slide actuation
The stainless barrel and M5x0.8 ports fit a compact sample-slide pusher in a water-testing rig where splashes would corrode painted bodies.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X25-30S the Right Cylinder?
With 100.5 N of push at 0.5 MPa, this 16 mm bore suits low-load clamping and sensing stations; step to a 20 mm bore (157.0 N push) if parts grow heavier, or drop to the fixed-stroke MAC version if the trim screw is never needed. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a lock, so the rod can still drift if air is lost. Mount with the FA flange or LB foot, add an I or Y rod knuckle where the load hangs off-axis, and order G or NPT threads if PT ports do not suit your manifold.
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 MACJ16X25-30S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those figures rise to 140.7 N push and 120.9 N pull. The theoretical ceiling at 1.0 MPa is 20.5 kgf for the 16 mm bore. Run it on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
The rolled stainless tube and hard-chrome 6 mm rod resist mild corrosion in damp or washed-down cells, unlike painted mini cylinders. A magnet is built in as standard, so CMSG / DMSG / EMSG switches mount without a special piston, and the FA flange or LB foot bolts straight to small fixtures.
