Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 80mm stroke, 1/8" 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 MACJ32X80-30S
A double-acting round-body mini cylinder, the MACJ32X80-30S adds a 30 mm adjustable extend window and a variable air cushion at each end. At 0.5 MPa it pushes 402 N and pulls 346 N, and its riveted stainless barrel with a hard-chromed 12 mm rod shrugs off mild corrosion, a real edge in damp or washdown-adjacent spots.
In practice, plan on roughly 241 N of usable work at 0.5 MPa to keep a healthy margin, enough for light clamping, ejecting small parts or driving a modest slide. The end-stop trim sets the extend stroke anywhere inside the 30 mm window on site, and the built-in magnet makes CMSG, DMSG or EMSG switch mounting a plug-on job.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X80-30S Is Used
Carton flap tuck station
Pushes flaps closed on a small packaging line; the 30 mm window lets operators fine-set the flap travel without re-plumbing the machine.
Bottle rejection pusher
Ejects off-spec bottles from a filler conveyor; 402 N at 0.5 MPa clears the lane quickly and the cushions soften each stroke reversal.
Glue-head indexing stop
Sets a repeatable extend position on a glue applicator; the adjustable stop trims travel as nozzle wear gradually changes the pattern.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X80-30S the Right Cylinder?
If 402 N at 0.5 MPa is more than you need, the 25 mm bore of the same family gives 245 N; step up to the 40 mm MACJ for about 628 N. Choose FA flange or LB foot mounting to suit the fixture, with I or Y rod knuckles for pivoting links. Remember the stroke adjuster is a mechanical end stop: it trims the extend stroke but holds nothing if air pressure falls.
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 MACJ32X80-30S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa, 563 N push and 484 N pull, with an 82 kgf theoretical maximum at 1.0 MPa. The extend stroke can be trimmed within a 30 mm window by the external stop screw, and speed runs 30-800 mm/s.
The barrel is stainless steel rolled onto aluminium covers, and the 12 mm rod is hard-chrome plated, so the cylinder tolerates humidity and light washdown far better than painted minis. Air ports are 1/8-inch and it operates on 0.15-1.0 MPa (22-145 psi).
