Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-30S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-30S is a genuine double acting, double rod, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 200mm 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 MACJ50X200-30S
A 50 mm bore round-body mini cylinder with a 200 mm stroke and a 30 mm adjustable window, the MACJ50X200-30S is double-acting with a variable air cushion at both ends. At 0.5 MPa it pushes with 981.3 N and pulls with 880.8 N, and the stainless barrel with a hard-chrome plated rod shrugs off washdown and damp shop air.
The extend stroke can be trimmed on site within the 30 mm window by the external stop screw, while the dual cushions let you run faster or carry heavier loads without hammering the covers. With the magnet built in as standard, CMSG, DMSG or EMSG switches clip on straight from the shelf. Keep real work around 589 N at 0.5 MPa, roughly 60 percent of the push rating.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
MAJ / MACJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-30S Is Used
Pick-and-place drop stop
On a tray packing line, the 30 mm window lets operators fine-tune how far the 16 mm rod lowers a 40 kg basket before release, with cushions softening the settle.
Gate diverter on conveyors
Swing or push a conveyor gate between lanes; pull force of 880.8 N at 0.5 MPa retracts the gate even with product loading against it.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X200-30S the Right Cylinder?
The stop screw shortens the extend stroke only; it is not a mid-stroke lock, so the rod will still drift if air is lost. Mount with an FA flange or LB foot, and pair I or Y rod knuckles where the load pivots.
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 MACJ50X200-30S FAQ
The theoretical ceiling at 1.0 MPa is 200.1 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere within the ordered 30 mm window, and a variable air cushion at both ends dials out end-of-stroke shock. It is a mechanical stop, not a load-holding brake: on air loss the piston still drifts. Stroke is set on site without swapping cylinders.
