Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 80mm 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 MACJ16X80-20S
The 20 mm window on this 80 mm stroke lets maintenance teams trim the extend position with a stop screw instead of shimming the fixture, and the variable air cushion at both ends can be tuned to kill end-of-stroke bang at higher speeds. Double-acting throughout, it delivers 100.5 N forward and 86.4 N return at 0.5 MPa on filtered air. Construction is a riveted stainless round barrel with aluminium covers and a hard-chrome 6 mm rod that resists corrosion in wet or food-line areas.
Run it anywhere in 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s. The theoretical ceiling at 1.0 MPa is 20.5 kgf, but plan real work around 60 N so the seals and cushion last. The magnet is factory built in - CMSG, DMSG and EMSG reed switches mount straight on for end-of-stroke signalling. Note the adjuster is purely an extend-side stop; it will not lock position if air pressure fails.

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 MACJ16X80-20S Is Used
Carton tab tucker
Folds small flaps on cosmetic cartons; the 20 mm window absorbs carton thickness variation without changing the fixture.
Fixture clamp
Clamps small aluminium brackets during drilling; 100.5 N at 0.5 MPa holds light parts while the cushion damps clamp-in impact.
Sensor target actuator
Moves a metal flag between positions on an assembly station, using the standard built-in magnet for cycle confirmation.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-20S the Right Cylinder?
Size against neighbours: at 0.5 MPa, bore 16 gives 100.5 N push while bore 20 jumps to 157.0 N - pick the larger bore if your 80 mm job needs more headroom or runs on a lower supply pressure. The 20 mm window covers moderate variation between part sizes. Mount via FA flange or LB foot; I and Y knuckles suit swinging loads. Treat the adjuster as an extend-side end stop, not a holding brake - the piston moves if supply air fails.
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 MACJ16X80-20S FAQ
Rated 100.5 N push and 86.4 N pull at 0.5 MPa; at 0.7 MPa that rises to 140.7 N push and 120.9 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. Supply air between 0.15-1.0 MPa (22-145 psi) and run the rod at 30-800 mm/s.
Both ends carry a variable air cushion: a needle valve bleeds the last air pocket so the piston decelerates before touching the cover. Turn it in for heavier loads or higher speeds to remove end-of-stroke shock and stretch seal life.
