Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X120-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X120-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 120mm 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 MACJ32X120-30S
Travel between 100 and 150 mm is often finalised late, and the MACJ32X120-30S answers that with a 30 mm adjust window trimmed from the stop screw - it shortens the extend stroke but never extends past 120 mm. Push force at 0.5 MPa is 402.2 N, giving roughly 241 N of practical working force or enough to raise about 20 kg vertically with a 2:1 margin. Variable cushioning at each end absorbs heavier or faster moves through the 30-800 mm/s range.
The riveted MA body pairs a stainless round barrel with aluminium covers and a hard-chrome 12 mm rod, a genuine edge over painted minis in food plants and outdoor gantries. The position magnet is standard for CMSG / DMSG / EMSG switches. The pressure envelope is 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), on air filtered to 40 um.

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 MACJ32X120-30S Is Used
Tray forming on a cartoner
Push formed trays off the forming die over 120 mm; the 30 mm window absorbs tray-depth variations between products.
Lift gate on a small CNC enclosure
Roughly 20 kg of vertical lifting with margin raises a hinged polycarbonate guard; cushioned ends stop the slam.
Fixture clamp on a welding jig
A 241 N-class working force holds steel tube against the jig; the stainless barrel tolerates grinding dust and weld-shop grime.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X120-30S the Right Cylinder?
Bore 32 is the middle choice at 402.2 N of push at 0.5 MPa, against 245.3 N for bore 25 and 628.3 N for bore 40. With 120 mm of stroke, guide the load externally whenever side forces appear - longer travels amplify rod bending. The mechanical trim stop sets position only and will not keep a suspended load in place if supply air fails. Choose FA flange or LB foot mounting and order I or Y knuckles for pivoting links.
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 MACJ32X120-30S FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; 563.0 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical peak at 1.0 MPa. Cycle speed is settable from 30-800 mm/s across 0.15-1.0 MPa (22-145 psi).
A stop screw shortens the extend stroke anywhere within the ordered 30 mm window, so technicians set position without swapping cylinders. It is a mechanical end stop, not a mid-stroke lock - the piston will still drift if pressure is removed.
