Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 225mm 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 MACJ16X225-40S
Where a machine stroke must be dialled in on the floor, the 40 mm window of the MACJ16X225-40S covers it: the extend stroke trims within that band and the variable cushion at both ends absorbs the last bit of shock. This 16 mm bore double-acting unit delivers 100.5 N at 0.5 MPa, so plan the real work around 60 N and keep the rest as reserve.
Its riveted stainless barrel with a hard-chrome carbon-steel rod copes with humid, food-adjacent and outdoor air. FA flange or LB foot mounting, optional I and Y knuckles, and the built-in magnet accepts CMSG, DMSG and EMSG switches out of the box.

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 MACJ16X225-40S Is Used
Pump dip-tube press
Seats dip tubes into cosmetic pump bottles on a semi-automatic bench; the 100.5 N push leaves plenty of reserve.
Cap presence gate
Swings a small check gate on a capping machine to reject uncapped jars before the filling station.
Light vertical lift
Lifts about 5 kg fixture plates or jigs with a 2:1 margin, guided by twin posts to protect the 6 mm rod.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-40S the Right Cylinder?
Sizing check: at 100.5 N push (0.5 MPa) this 16 mm bore covers light clamping and gate duty; if the load needs more, the 32 mm bore offers 402.2 N at the same pressure. Keep working force near 60 N and hold the remainder back for pressure dips. On a 225 mm stroke the 6 mm rod should see axial force only, so guide the load externally.
The 40 mm trim range comes from the end-stop adjuster, which shortens extend travel but never locks the load when air fails. FA flange or LB foot brackets, plus optional I and Y knuckles, and the built-in magnet works with CMSG / DMSG / EMSG switches.
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 MACJ16X225-40S FAQ
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push at 0.7 MPa, and 20.5 kgf maximum theoretical at 1.0 MPa. Stroke trims within the 40 mm window, pressure spans 0.15-1.0 MPa (22-145 psi), speed runs 30-800 mm/s, and ports are M5x0.8 with an M6x1.0 rod thread.
Choose FA flange or LB foot brackets; I and Y rod knuckles are also available in this series. Because the magnet is factory-fitted as standard, CMSG, DMSG and EMSG switches sense end positions with no special piston order, sitting directly on the stainless barrel of the 225 mm body.
