Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X15-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X15-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 15mm 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 MACJ16X15-20S
A 15 mm stroke, 16 mm bore MACJ with a 20 mm adjustable extend window and a variable air cushion at both ends. Double-acting throughout: air drives the rod out and pulls it back at 30-800 mm/s on 0.15-1.0 MPa (22-145 psi). At 0.5 MPa it pushes 100.5 N, which translates to a vertical lift of about 5 kg with a 2:1 margin, and 140.7 N at 0.7 MPa.
The stainless round barrel and 20 um hard-chrome plated rod shrug off splashes and washdown better than painted minis, while the riveted aluminium covers keep the body reliably sealed. A magnet ships as standard, so CMSG, DMSG or EMSG switches clip on without ordering a special piston.

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 MACJ16X15-20S Is Used
PCB test nest ejection
The 100.5 N push at 0.5 MPa is enough to lift finished circuit boards out of a test fixture nest, and the 20 mm trim window absorbs fixture height changes.
Cosmetic cap seating
Short-stroke pressing of snap caps onto 15 ml vials on a filling line, where the dual variable cushions keep the seating impact gentle at speed.
Vibratory bowl stop pin
A stainless 6 mm rod trimmed by the -20 adjuster makes a durable, splash-tolerant stop pin for a vibratory parts feeder.

Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X15-20S the Right Cylinder?
Need more muscle? Step up to the 20 mm MA bore for 157.0 N push at 0.5 MPa; there is no smaller MA bore, so if 100.5 N overshoots your load, lower the supply pressure instead of downsizing. The 20 mm trim range lets you dial the extend stroke on site, but the stop screw is an end stop only and will not hold a load if air is lost. FA flange or LB foot mounting, PT threads standard with G and NPT options.
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 MACJ16X15-20S FAQ
At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those figures rise to 140.7 N and 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The -20 suffix sets a 20 mm window in which an external stop screw trims the extend stroke on site. It shortens the stroke, never lengthens it, and because the adjuster is a mechanical end stop rather than a brake, the rod can still drift if air pressure drops.
