Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 50mm 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 MACJ16X50-10S
When the last few millimetres of positioning matter most, this 10 mm window is the tool: the stop screw on the MACJ16X50-10S trims the extend stroke by up to 10 mm from its 50 mm length, and the variable cushion at each end softens whatever remains. Thrust from the 16 mm bore reads 100.5 N out and 86.4 N back at 0.5 MPa, reaching 140.7 N out at 0.7 MPa.
Like every MA cylinder it is a riveted round body - stainless barrel, aluminium covers, hard-chrome rod - with seals chosen to hold grease along the bore, so nothing needs retightening after months in a humid filling room. Planning real work at about 60 N of the rated push leaves headroom for friction and load swings in indexing fixtures. The piston magnet ships fitted, letting CMSG / DMSG / EMSG switches drop straight onto the barrel, and the supply span is 0.15-1.0 MPa (22-145 psi).

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 MACJ16X50-10S Is Used
Sample tray stopper
Halts 30-place microtube trays at a pick station in a cold-store doorway, well inside the cylinder's -20 to +70 C rating; the fine 10 mm window sets the exact stop depth.
Label sensor flag
Drives a flag through a label-web sensor path; the standard magnet plus a CMSG / DMSG / EMSG switch confirms the flag home position every cycle.
Web guide trim
Makes small lateral corrections on a film web guide, where 86.4 N of pull return holds the guide roller against drift at 0.5 MPa.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-10S the Right Cylinder?
Size check: this 16 mm bore provides 100.5 N at 0.5 MPa; if the fixture needs more, the 20 mm bore in the same series reaches 157 N at the same supply. Because the adjuster acts as an extend-side end stop rather than a position lock, treat it as a repeatability aid, not a clamp - the piston is free to move if pressure drops. Choose FA flange or LB foot plates, thread the M5x0.8 ports to your manifold, and fit CMSG / DMSG / EMSG switches straight onto the magnet-equipped barrel.
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 MACJ16X50-10S FAQ
0.5 MPa: 100.5 N extend, 86.4 N retract. 0.7 MPa: 140.7 N extend, 120.9 N retract. Maximum theoretical: 20.5 kgf at 1.0 MPa supply. The adjustment window is 10 mm on the 50 mm extend stroke, cushioning is variable at both ends, and the operating envelope is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
No. The adjuster is a mechanical end stop that trims the extend stroke for repeatable positioning - it is not a mid-stroke lock, and the piston will still drift if air pressure is lost. For load holding, add a locking valve or a separate brake to the circuit.
