Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 300mm 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 MACJ16X300-10S
A compact round-body actuator built around a stainless-steel barrel and a hard-chrome plated rod, the MACJ16X300-10S extends and retracts on air with a variable cushion at each end. Its extend stroke can be trimmed on site within a 10 mm window by the external stop screw, and the riveted aluminium covers keep the 16 mm bore body sealed on its smooth round tube.
At 0.5 MPa the piston pushes 100.5 N and pulls 86.4 N, which in practice means planning jobs around roughly 60 N of real work. The magnet is fitted as standard, so CMSG, DMSG or EMSG switches clamp straight onto the barrel, and the mild-corrosion resistance of the stainless tube makes it a fit for damp or washdown-prone corners of a line.

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 MACJ16X300-10S Is Used
PCB push-off
Ejecting populated circuit boards off a transfer rail into an inspection nest, where the 10 mm trim dials travel to the exact rail height.
Vial tray indexing
Advancing sample vial trays one pocket at a time on a lab filling line; about 60 N of usable thrust suits light plastic carriers.
Cosmetic cap press
Seating snap-on caps onto small cream jars with a gentle, cushioned 100.5 N press that will not crush thin walls.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-10S the Right Cylinder?
Bore 16 is the smallest MA size, so nothing sits below it; if 100.5 N at 0.5 MPa feels tight, step up to bore 20 (157.0 N) or bore 25 (245.3 N) rather than running this one near its limit. Keep real workloads near 60 N and let the cushion absorb the last few millimetres. Note that the stop screw sets extend travel only - it is not a position lock, and the rod can still drift if air is lost.
Mount on an FA flange or LB foot, add I or Y rod knuckles where the load pivots, and clip a CMSG switch to the barrel for end-of-stroke signals. Porting is a single M5x0.8. Over a 300 mm stroke the 6 mm rod will bend under side load, so guide the payload externally and couple through a knuckle or floating joint.
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 MACJ16X300-10S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N. The theoretical ceiling is about 20.5 kgf at 1.0 MPa. Supply pressure runs 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s.
No - every MA-series cylinder ships with the piston magnet built in, so CMSG, DMSG or EMSG switches clip onto the stainless barrel straight out of the box.
