Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MACJ32X75-20S
Double-acting with an on-board stroke trim, the MACJ32X75-20S lets a stop screw shorten the extend stroke anywhere inside a 20 mm window, then cushions both ends with variable air. At 0.5 MPa it pushes 402 N and pulls 346 N, so a 75 mm stroke suits mid-weight clamping and feeding across a 30-800 mm/s speed band.
The round body is a riveted stainless barrel with a hard-chrome plated 12 mm rod, so damp washdown corners and outdoor cabinets do not chew it up the way painted minis fail. Every unit ships with the magnet fitted as standard, letting CMSG, DMSG or EMSG switches clip straight on. Treat the trim screw as an end stop only: if air is lost the piston still drifts, so it is not a load lock.

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 MACJ32X75-20S Is Used
Fixture clamp on a CNC jig
Holds aluminum brackets against a drilling jig; the 20 mm trim sets clamp height without stacking shims.
Conveyor stopper gate
Pops a stop blade into a carton lane at up to 800 mm/s, cushioned so the blade never chatters against the guide.
Lid press on a filling line
Snaps caps onto 250 ml bottles; variable cushioning keeps the 82 kgf-class press gentle on the tooling.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X75-20S the Right Cylinder?
Size check: bore 25 delivers 245 N at 0.5 MPa and bore 40 delivers 628 N, so this 32 mm unit at 402 N sits squarely between them. Budget about 241 N for actual work at 0.5 MPa rather than the full rating. Mount with an FA flange or LB foot, and the I or Y rod knuckle handles linkage joints; SDB and back-cover codes do not apply to adjustable versions. Ports are 1/8 inch on this bore.
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 MACJ32X75-20S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa, 563 N push and 484 N pull. Theoretical maximum is 82 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi).
Yes - the magnet is built in as standard on the MA series, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel with no special piston or retrofit work.
