Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X160-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X160-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 160mm 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 MACJ16X160-40S
Within the 16 mm MA range, the MACJ16X160-40S is a double-acting round-body mini cylinder with an adjustable extend stroke. An external stop screw shortens the stroke anywhere inside the ordered 40 mm window, and a variable air cushion at both ends soaks up end-of-travel shock. At 0.5 MPa it delivers 100.5 N of push and 86.4 N of pull.
The riveted stainless barrel and hard-chrome plated rod handle damp, washdown-prone corners far better than painted minis. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on without a special-order piston. In practice, plan on roughly 60 N of real working force at 0.5 MPa, or about 5 kg of vertical lift with a 2:1 margin.

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 MACJ16X160-40S Is Used
Bottling-line reject pusher
Knocks a mis-capped bottle off a narrow conveyor lane at 100.5 N, with the 40 mm trim letting maintenance match the lane without re-piping air lines.
Fixture part ejection
Ejects a finished bushing from a small drilling fixture; the trim window absorbs fixture rework and the dual cushions stop the 6 mm rod slamming home.
Vial indexing on a lab bench
Steps sample vials along a benchtop indexer at 30-800 mm/s, with DMSG switches confirming each 160 mm advance on the standard magnet.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X160-40S the Right Cylinder?
If 100.5 N is too little, step up to the 20 mm bore (157.0 N push at 0.5 MPa) or the 25 mm bore (245.3 N). The 6 mm rod keeps a 160 mm travel light, but keep side loads off it and guide the part separately. FA flange and LB foot mounts, plus I and Y rod knuckles, cover most fixings, and the male rod thread is M6x1.0 with M5x0.8 ports. The stop screw only trims the extend stroke - if air drops, the piston still drifts, so do not rely on it to park a load.
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 MACJ16X160-40S FAQ
At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N; at 0.7 MPa that rises to 140.7 N push and 120.9 N pull, with a theoretical peak of 20.5 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s on air filtered to 40 um.
No. The stop screw simply caps the extend stroke anywhere inside the 40 mm window; it is not a mid-stroke lock, and on air loss the piston drifts. Both ends carry a variable air cushion for soft landings, and FA flange or LB foot mounts suit most frames.
