Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MACJ32X300-50S
With 300 mm of travel and a 50 mm trim window, the MACJ32X300-50S covers long push-and-return jobs where the stop position has to be dialed in after installation. It is double-acting with a variable air cushion at both ends; the 32 mm bore pushes 402 N at 0.5 MPa and 563 N at 0.7 MPa, across a supply range of 0.15-1.0 MPa (22-145 psi) and speeds from 30 to 800 mm/s.
As a vertical lifter, the 402 N extend rating equates to about 41 kg - plan on raising roughly 20 kg to keep a comfortable 2:1 margin. The riveted round body keeps a stainless barrel and a hard-chrome plated 12 mm rod working in washdown-prone corners where painted mini cylinders rust out. The magnet comes as standard, so CMSG, DMSG and EMSG switches mount straight onto the barrel.

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 MACJ32X300-50S Is Used
Carton diverter
Kicks cartons off a sorting lane on a warehouse conveyor; 402 N at 0.5 MPa clears typical 15 kg parcels with speed to spare.
Sliding guard door
Opens a machine-guard sliding door across its full 300 mm travel; the 50 mm adjustable stop sets the exact opening width after install.
Pallet stopper
Raises a stop blade at the end of a pallet conveyor lane; roughly 240 N of usable push at 0.5 MPa holds light pallet flow in check.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X300-50S the Right Cylinder?
Compare forces before committing: the 25 mm bore manages 245 N at 0.5 MPa and the 40 mm bore reaches 628 N, so step up if friction or gravity eats into the 402 N rating. On a 300 mm stroke, keep side loads low - a 12 mm rod loaded sideways over this travel will bend long before the cushion can help; guide the load externally if needed. The stop screw fixes the extend end only; with air removed the piston is free to move, so add a separate lock for hanging loads. FA flange or LB foot mounting; I and Y knuckles fit the rod.
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 MACJ32X300-50S FAQ
Extend force is 402.2 N and retract 345.6 N at 0.5 MPa; raise the supply to 0.7 MPa and extend reaches 563.0 N. Maximum theoretical output at 1.0 MPa is 82 kgf. Proof pressure stands at 1.5 MPa (215 psi) with a working range of 0.15-1.0 MPa (22-145 psi).
The stop screw shortens the extend stroke anywhere inside the 50 mm window, and because the cushioning is a variable air cushion rather than a fixed bumper, it keeps absorbing energy at whatever trimmed position you choose. Stroke speed of 30-800 mm/s can therefore run higher than an uncushioned mini of the same size would survive.
