Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MACJ32X20-10S
A short-travel, double-acting round-body cylinder, the MACJ32X20-10S lets you shorten the extend stroke on site anywhere within its 10 mm window, with a variable air cushion at each end to kill impact. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N, peaking at 82 kgf theoretical.
Its riveted stainless barrel and hard-chrome plated 12 mm rod stand up to washdown and damp air far better than painted minis. Sized sensibly, count on about 241 N of usable push at 0.5 MPa, enough to raise roughly 20 kg vertically even after doubling your margin.

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 MACJ32X20-10S Is Used
Press die ejection
Ejects small stamped parts from a punch die with a push tuned anywhere from 10 to 20 mm, landing soft on the cushion.
Weld jig clamping
Clamps brackets against a fixture stop in automotive weld cells, where the trim screw sets the exact grip point per part.
Reject kicker
Kicks failed assemblies off a bench-top inspection conveyor with 402 N of push, so cycle speed stays high even on sticky parts.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X20-10S the Right Cylinder?
Compare before you buy: the MACJ25 pushes 245.3 N at 0.5 MPa and may suffice, while the MACJ40 raises the figure to 628.3 N if you want reserve. Note that the adjuster only shortens the extend stroke - it is an end stop, not a mid-stroke lock, so the rod will drift if air pressure is lost. FA flange and LB foot mounts plus the standard magnet (CMSG/DMSG/EMSG compatible) cover most fixture needs.
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 MACJ32X20-10S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa that rises to 563.0 N push and 483.8 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
The barrel is stainless steel rolled onto aluminium covers, and the 12 mm piston rod is hard-chrome plated carbon steel. That combination shrugs off mild corrosion and rinsing, a real advantage over painted mini cylinders in food and damp environments.
