Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-30S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-30S is a genuine double acting, double rod, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 175mm 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 MACJ50X175-30S
Where a fixed-stroke MAC would force a re-order after every layout change, the MACJ50X175-30S gives a 30 mm tuning band on the extend side, set with an external screw at commissioning. Air works both directions, cushions at each end absorb the stop, and speed stays controllable between 30 and 800 mm/s. This 50 mm bore pushes 981.3 N and pulls 880.8 N at 0.5 MPa; at 0.7 MPa push rises to 1373.8 N, and the theoretical ceiling is 200.1 kgf at 1.0 MPa within the 0.15-1.0 MPa (22-145 psi) pressure window.
Round stainless barrel, riveted aluminium covers and a hard-chrome 16 mm rod give it the corrosion resistance painted mini cylinders lack, which matters in food plants and wet workshops. The piston magnet is included as standard - CMSG, DMSG and EMSG switches mount with no special order.

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 MACJ50X175-30S Is Used
Mold ejector assist
Strips cooling parts from a shallow plastics mold; the 30 mm trim band lets technicians set ejection height per mold without swapping cylinders.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-30S the Right Cylinder?
This 50 mm unit in between gives 981.3 N and a 30 mm trim band, a good match when the exact stop point will only be known at installation. Long strokes amplify side loads, so guide the payload separately instead of leaning on the 16 mm rod. Fit the FA flange for face mounting, the LB foot for base mounting, and an I or Y knuckle where the joint must pivot - the trim stop shortens extend travel only and will not arrest a falling or spring-loaded load once air is gone.
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 MACJ50X175-30S FAQ
Pressure band is 0.15-1.0 MPa (22-145 psi), ports are 1/4", and the 16 mm rod carries an M14x1.5 male thread.
The MACJ's variable air cushion at both ends can be tuned for the exact speed and load, so faster cycles or heavier tooling stop softly, while the MAJ relies on fixed bumpers. If the job has no stop-position changes, the fixed-stroke MAC is the simpler sibling; if you need a rod on both ends, that is the MACD. All ship with the magnet fitted for CMSG / DMSG / EMSG switches.
