Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 190mm 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 MACJ32X190-30S
Order the MACJ32X190-30S and you get a 30 mm trim window: the extend stroke can be set anywhere inside that band with an external stop screw, while retraction stays at the full 190 mm. Double-acting, with a variable cushion at each end to tune deceleration.
At 0.5 MPa this 32 mm bore generates 402 N pushing and 346 N pulling; counting about 241 N as usable thrust at that pressure keeps the cylinder in its comfort zone. The stainless barrel and 20 um hard-chrome rod take coolant mist and damp air in stride, and the standard magnet lets CMSG, DMSG or EMSG switches signal stroke ends out of the box.

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 MACJ32X190-30S Is Used
Tray forming on a thermoformer
Ejects formed trays from the mold; the 30 mm window trims ejection depth as tray sizes change.
Lane merge gate on a pharma line
Routes blisters into a checkweigher lane; cushions absorb fast cycles while the switch-ready magnet confirms gate position.
Door assist on an oven loader
Opens a bake-oven loading door against a light counterweight; the stainless barrel shrugs off heat-adjacent humidity and flour dust.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X190-30S the Right Cylinder?
One bore down, MACJ25 offers 245 N push at 0.5 MPa; one up, MACJ40 offers 628 N - size by real load, not bore size. At 190 mm of travel, brace side loads with external guides or an I/Y knuckle; FA flange and LB foot choices cover fixed mounting.
The adjuster is a hard extend-side stop, so a drifting piston under air loss is normal - it will not act as a brake. Ports are 1/8" at 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 MACJ32X190-30S FAQ
Push 402 N, pull 346 N at 0.5 MPa; push 563 N, pull 484 N at 0.7 MPa; 82 kgf theoretical at 1.0 MPa. Working range is 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s, with the extend stroke adjustable over a 30 mm window.
No - it is a mechanical end stop that shortens the extend stroke within the 30 mm window, not a mid-stroke lock or brake. If the load must stay put when air is lost, add a piloted check or blocking valve to the circuit.
