Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X450-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X450-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 450mm 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 MACJ50X450-10S
Fine end-point setting over a 450 mm reach is what this model is for: the 10 mm adjust window lets you dial the extend stop in millimetres while the bore still delivers 981.3 N push and 880.8 N pull at 0.5 MPa (0.15-1.0 MPa / 22-145 psi overall). At 0.7 MPa the push rises to 1373.8 N and the theoretical 1.0 MPa figure is 200.1 kgf. Budget about 589 N for real work at 0.5 MPa and the cylinder will hold its cycle rate over long runs.
MACJ bodies are riveted stainless round tubes with a 20 um hard-chrome rod and grease-retaining two-way seals, so mist, splash and outdoor exposure age them slowly. The piston magnet is factory standard; add CMSG, DMSG or EMSG switches for end-of-stroke signalling without special ordering. Note the trim screw is a mechanical end stop rather than a holding brake: drop the air and the rod can be pushed back.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X450-10S Is Used
Fixture stop tuning
Machining fixture clamps push parts onto a hard stop; the 10 mm trim compensates for fixture tolerance without shimming.
High-bay door closer
The 450 mm stroke closes tall warehouse access doors, and the stainless barrel handles unheated, humid interiors.
Bale sampler ram
Presses a sample probe into cotton bales with 1373.8 N at 0.7 MPa while the cushions soften probe withdrawal.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X450-10S the Right Cylinder?
If your load only needs about 377 N of working force, the 40 mm bore (628.3 N push at 0.5 MPa) saves air; if you sit near the 589 N working ceiling of this bore, step up to the 63 mm bore with 1557.9 N. The narrow 10 mm window suits a fixed fixture height that needs only stop-tuning. Use the FA flange or LB foot, fit an I or Y rod knuckle where tooling swivels, and on a 450 mm stroke keep the load guided externally so the 16 mm rod never sees bending. Both ends carry a variable cushion across the 30-800 mm/s speed range.
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 MACJ50X450-10S FAQ
Push 981.3 N, pull 880.8 N at 0.5 MPa; push 1373.8 N, pull 1233.1 N at 0.7 MPa; 200.1 kgf theoretical maximum at 1.0 MPa. Working pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, port 1/4 inch, rod thread M14x1.5.
The riveted stainless tube and hard-chrome plated rod resist corrosion in washdown and outdoor air far better than painted minis, while the variable air cushion at both ends removes end-of-stroke shock when you run fast.
