Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X250-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X250-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MACJ32X250-75S
With a 75 mm on-site trim range across its 250 mm stroke, the MACJ32X250-75S lets one cylinder serve several part heights or gate positions. It is double-acting with a variable air cushion at both ends, and at 0.5 MPa it pushes 402.2 N while pulling 345.6 N. Run it anywhere from 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The round stainless barrel riveted to aluminium-alloy covers stays sealed and corrosion-free in damp plants, a genuine edge over painted minis in food or outdoor lines. The magnet comes standard, so CMSG / DMSG / EMSG switches drop straight on. In practice, plan on roughly 241 N of usable push at 0.5 MPa - enough to lift about 20 kg vertically with a comfortable 2:1 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 MACJ32X250-75S Is Used
CNC fixture clamping arm
Clamps tall workpieces on a machining jig; trim the 75 mm window to match different part heights without swapping cylinders.
Case flap folder
Folds top flaps on a carton sealer along the 250 mm stroke, with the variable cushion softening the fold-over hit at speed.
Bin-fill diverter
Swings a divert chute between two filling bins; a CMSG switch on the standard magnet confirms which route is active.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X250-75S the Right Cylinder?
Sizing check: this 32 mm bore gives 402.2 N push at 0.5 MPa - budget about two thirds of that for real work. Bore 25 tops out at 245.3 N and bore 40 reaches 628.3 N at the same pressure, so move one step only when the load demands it. If the load must stay put on air loss, remember the 75 mm adjuster is an end stop, not a lock; choose the MACD double-rod version or add external stops instead. FA flange and LB foot mountings, plus I and Y rod knuckles, cover most frame designs.
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 MACJ32X250-75S FAQ
Full figures: 402.2 N push and 345.6 N pull at 0.5 MPa; 563.0 N push at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. The rod is 12 mm with M10x1.25 thread and the air port is 1/8 inch, sized by the 32 mm bore.
No. Every MA-series cylinder ships with a built-in magnet as standard, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel and report both end positions without any special-order hardware.
