Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-10S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-10S 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 MACJ50X175-10S
Ten millimetres of on-site trim is the whole point of the MACJ50X175-10S: an external stop screw shortens the extend stroke by up to 10 mm so the same cylinder can be re-tuned when the fixture or stop position changes. It is double-acting, so air drives the rod out and back, and a variable air cushion at both ends lets you soften landing shock anywhere in the 30-800 mm/s speed band.
Construction is a riveted round body: stainless barrel, hard-chrome plated carbon-steel rod, aluminium covers - no tie rods to retighten, and a build that tolerates washdown and damp plant air far better than painted minis. The magnet is standard on every MA cylinder, so CMSG, DMSG or EMSG switches clip straight on without a special-order piston.

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 MACJ50X175-10S Is Used
Carton stopper gate
Raises a stop blade to halt cartons on a packaging conveyor; 880.8 N of pull retracts the pin briskly and the built-in magnet feeds a CMSG switch for gate-position feedback.
Reject pusher on filler line
Ejects off-weight bottles from a rotary filler discharge; the variable cushion lets the pusher run near the 800 mm/s top speed without hammering the cover.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X175-10S the Right Cylinder?
Size by force, not bore pride: the 40 mm MACJ40 pushes 628.3 N at 0.5 MPa and will do if your work sits under roughly 600 N, while the 63 mm MACJ63 at 1557.9 N is the step up once you pass about 900 N of real load. A 175 mm stroke on a 16 mm rod is fine for guided loads, but keep the payload on its own guide - the rod is not meant to carry side force over a long span. Mount on the FA flange or LB foot, fit an I or Y knuckle if the linkage needs it, and note the adjustable series omits the SDB option. Because the trim screw only stops the rod while air is applied, never count on it to hold a load if the supply fails.
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 MACJ50X175-10S FAQ
At 0.5 MPa it pushes 981.3 N (about 100 kgf) and pulls 880.8 N. At 0.7 MPa push rises to 1373.8 N and pull to 1233.1 N. Theoretical maximum at 1.0 MPa is 200.1 kgf. Port is 1/4", rod thread M14x1.5, rod 16 mm, operating pressure 0.15-1.0 MPa (22-145 psi).
No. The stop screw shortens the extend stroke by up to 10 mm and acts only while air pressure is present; if the supply fails, the piston can still be moved by the load. For true holding, add a check or locking valve in the circuit. The variable cushions at both ends handle deceleration across the 30-800 mm/s range - not holding.
