Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-30S 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 MACJ16X80-30S
Shortening the extend stroke is done on the machine, not in the order book: order the 80 mm stroke and trim it anywhere within 30 mm using the built-in stop screw. Both ends carry a variable air cushion, so faster cycles or heavier light loads land softly on the aluminium covers. At 0.5 MPa the bore 16 piston gives 100.5 N push and 86.4 N pull; push it to 0.7 MPa and forward force climbs to 140.7 N.
The stainless barrel and hard-chrome plated rod stand up to splash, humidity and periodic washdown where painted mini cylinders blister. It holds about 10 kg vertically in theory at 0.5 MPa - treat 5 kg as the practical lift with a 2:1 margin. The magnet comes standard for CMSG, DMSG and EMSG switches; the trim screw is a hard stop for the extend stroke only and never acts as a brake against load drop.

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 MACJ16X80-30S Is Used
Glue bead follower
Presses a dosing nozzle onto a bead line; the 30 mm trim range is reset during commissioning as nozzle wear opens the gap.
Vial sorting kicker
Deflects small vials into a reject lane at 30-800 mm/s, with the cushion tuned so glass never cracks against the stop.
Terminal block press
Seats wire ferrules into terminal blocks with roughly 60 N of real force, trimmed to each block series within the 30 mm window.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X80-30S the Right Cylinder?
If 100.5 N at 0.5 MPa feels thin for the task, bore 20 delivers 157.0 N and bore 32 reaches 402.2 N at the same pressure; the 30 mm trim window makes this cylinder a good fit when the final stop position will be tuned during commissioning. FA flange or LB foot fixing, plus I or Y rod knuckles, cover most mini-machine layouts. The trim screw only limits the extend stroke and will not arrest a falling load when air is cut.
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 MACJ16X80-30S FAQ
Push 100.5 N and pull 86.4 N at 0.5 MPa; push 140.7 N and pull 120.9 N at 0.7 MPa; 20.5 kgf theoretical maximum at 1.0 MPa. Working pressure 0.15-1.0 MPa (22-145 psi), speed range 30-800 mm/s, air port M5x0.8, rod thread M6x1.0.
The round barrel is stainless steel rolled directly onto aluminium covers, and the 6 mm rod carries a hard-chrome plating about 20 um deep. That combination resists splash, humidity and periodic washdown far better than painted-steel mini cylinders in food or outdoor cells.
