Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-50S 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 MACJ16X225-50S
An AirTAC MA-series round-body mini cylinder in the MACJ version: double-acting, with an extend stroke you can trim on site by up to 50 mm and a variable air cushion at both ends. At 0.5 MPa this 16 mm bore delivers 100.5 N on the extend stroke and 86.4 N on retract, rising to 140.7 N at 0.7 MPa.
The stainless barrel and hard-chrome plated 6 mm rod handle damp and washdown spots far better than painted minis, and the riveted aluminium covers keep the body sealed. Every unit carries a built-in magnet, so CMSG / DMSG / EMSG switches clip on without a special piston. In practice, budget roughly 60 N for real work at 0.5 MPa - about a 5 kg vertical lift with a 2:1 margin.

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 MACJ16X225-50S Is Used
Carton diverter on a packaging line
The 225 mm travel sweeps cartons across a belt lane, and the 50 mm trim lets the pusher park clear of the product stream.
Hopper slide-gate actuator
Cycles a slide gate on a small dosing hopper; the twin cushions absorb the slam as the gate seats, even near 800 mm/s.
Inspection raise-and-hold fixture
Raises a light camera bracket of about 5 kg into the vision position; CMSG switches on the built-in magnet confirm both end positions.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X225-50S the Right Cylinder?
Need more muscle? Bore 20 pushes 157.0 N at 0.5 MPa in the same MA family; bore 25 reaches 245.3 N. The 225 mm stroke sits within the 300 mm standard range for this bore, but a 6 mm rod is slender - carry side loads on external guides and anchor with the LB foot or FA flange, adding an I or Y rod knuckle if the load pivots. The trim screw shortens the extend stroke only; it is a stop, not a lock, so the rod can drift if air is lost.
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 MACJ16X225-50S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa, 140.7 N push and 120.9 N pull. Theoretical maximum is 20.5 kgf at 1.0 MPa. Stroke is 225 mm with a 50 mm adjustable window on the extend side, cushioned at both ends, running 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
FA flange and LB foot mounts plus I and Y rod knuckles cover most fixtures, the port is M5x0.8, and the male rod thread is M6x1.0. The magnet comes standard, so CMSG, DMSG or EMSG switches mount straight onto the barrel - no special-order piston.
