Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 75mm stroke, 1/4" 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 MACJ50X75-75S
A riveted round-body mini cylinder with a stainless-steel barrel and a hard-chrome plated rod, the MACJ50X75-75S pushes 981 N at 0.5 MPa and pulls 881 N. Air drives the piston both ways, and a stop screw sets the extend stroke anywhere inside the 75 mm window you ordered. A variable air cushion at each end soaks up end-of-stroke shock, so you can cycle faster without hammering the covers.
The grease-storing two-way piston seal runs long shifts in aluminium-alloy covers, and the magnet comes built in as standard, so CMSG, DMSG or EMSG switches drop straight on. Plan on roughly 589 N of realistic working push at 0.5 MPa once you keep a 40% margin - that slides a loaded 50 kg crate along a roller rail without straining the bore.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X75-75S Is Used
Carton rejector
Kicks misprinted cartons off a food-packaging conveyor; the 75 mm window lets line staff fine-tune the push distance without swapping cylinders.
Small lid press
Snaps caps onto 20 L pails at a bottling bench - 981 N at 0.5 MPa is ample for light snap-fits, and the cushion keeps the die from slamming.
Welding jig clamp arm
Clamps aluminium extrusions on a fabrication jig; the stainless barrel and hard-chrome rod tolerate grinding dust and coolant mist around the cells.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X75-75S the Right Cylinder?
Against neighbours, the 40 mm bore delivers 628 N at 0.5 MPa and the 63 mm bore 1558 N, so this 50 mm barrel is the middle band: under 600 N of demand, step down; above 1400 N, step up. Note the stop screw only fixes where extend ends - it is not a mid-stroke lock, and the rod can still drift if air pressure is lost, so add a valve when the load must stay put. FA flange or LB foot mounting, I and Y rod knuckles, PT / G / NPT ports and the standard magnet 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 MACJ50X75-75S FAQ
At 0.5 MPa it pushes 981 N (about 100 kgf) and pulls 881 N; at 0.7 MPa those rise to 1374 N push and 1233 N pull. The theoretical ceiling is 200 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the extend stroke is settable anywhere within the 75 mm window.
The stainless barrel plus the 20 um hard-chrome rod shrug off mild corrosion and washdown that rust painted-steel minis, and the built-in magnet (standard, not an option) lets you add CMSG / DMSG / EMSG position switches at any time.
