Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X100-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X100-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 100mm 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 MACJ16X100-20S
Double acting, cushioned at each end, and tunable: the MACJ16X100-20S lets a stop screw pull the extend stroke back by as much as 20 mm from its 100 mm ordered travel. The actuator wraps a stainless steel tube in a rolled, riveted body with aluminium covers, swinging a hard-chrome carbon-steel rod that copes with washdown corners and outdoor mist. Rated 100.5 N push and 86.4 N pull at 0.5 MPa.
For sizing, treat about 60 N as the honest working force at 0.5 MPa - that lifts close to 5 kg vertically once you halve the raw 10 kg equivalent for margin. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-800 mm/s. The magnet is standard fitment, so CMSG / DMSG / EMSG sensors attach with no option codes.

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 MACJ16X100-20S Is Used
Vertical indexing pin
Drops a locating pin into fixture bushings under an SMT stencil cart, trimmed per tray height within the 20 mm window.
Tote latch release
Pops latch hooks on dairy totes at a washdown palletiser, where the stainless barrel handles caustic rinse cycles.
Glue-dab station

Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X100-20S the Right Cylinder?
Consider the MACD16X100 double-rod version if you ever need a rod at both ends - this adjustable model has no double-rod variant. If 100.5 N at 0.5 MPa is marginal for your load, bore 20 offers 157.0 N in the same family. The screw trims stroke but does not lock it: with air lost, the piston can be back-driven, so fit an external check for suspended loads. Long 100 mm strokes on a 6 mm rod dislike side loads - carry the load on an external guide and keep the cylinder in pure push-pull. FA flange or LB foot, I and Y knuckles, and PT / G / NPT threads (M5x0.8 on this bore) round out the order.
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 MACJ16X100-20S FAQ
Full figures: 100.5 N push and 86.4 N pull at 0.5 MPa; 140.7 N push and 120.9 N pull at 0.7 MPa; and a theoretical maximum of 20.5 kgf at 1.0 MPa. A practical target is about 60 N of working force at 0.5 MPa, near 5 kg of vertical lift.
Each end carries a variable air cushion: turn the adjustment screw to meter the exhaust and the 100 mm stroke decelerates progressively instead of hammering the covers. That lets you push toward the top of the 30-800 mm/s band with heavier jigs and still get a soft landing, with no external shock absorbers needed on light loads.
