Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X225-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X225-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 225mm 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 MACJ50X225-10S
Washdown lines and humid plants are where this stainless mini earns its keep: the riveted round barrel resists mild corrosion that quickly ruins painted-steel minis, and the hard-chrome plated 16 mm rod keeps scoring at bay through thousands of cycles. Push force is 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa, with a tight 10 mm stop-screw window for trimming the extend stroke. Air supply is 0.15-1.0 MPa (22-145 psi).
In practice, plan on around 589 N of real work at 0.5 MPa rather than the full rating, which leaves margin for friction and pressure droop. The variable air cushion at both ends dials out end-of-stroke shock across the 30-800 mm/s speed range, and the magnet fitted as standard accepts CMSG / DMSG / EMSG switches with no 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 | 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 MACJ50X225-10S Is Used
Drill-head clamp trim
A 10 mm band is enough to dial the clamp shoe onto aluminium housings after each fixture change in a small machining cell.
Bottle-rinse carriage
Carries rinse nozzles into a stainless wash tunnel; damp, splashy duty the chrome rod and rolled tube handle without paint flaking off.
Carton platen top-off
Tucks flaps on a case packer; the last 10 mm of travel can be shortened so the platen seats exactly on taller cartons.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X225-10S the Right Cylinder?
Compared with the 40 mm bore (628.3 N at 0.5 MPa) this 50 mm unit offers 981.3 N; the 63 mm bore takes it further to 1557.9 N. Air at 0.15-1.0 MPa (22-145 psi) feeds 1/4 in. ports, rod thread M14x1.5. FA flange, LB foot and I / Y knuckle mountings cover most frames. The external stop shortens extend stroke within the ordered 10 mm window but is not a load-holding brake: with air lost the rod still drifts. Long strokes like 225 mm deserve external guidance if the load is not self-aligning.
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 MACJ50X225-10S FAQ
Push is 981.3 N and pull 880.8 N at 0.5 MPa; at 0.7 MPa expect 1373.8 N push and 1233.1 N pull, peaking at 200.1 kgf theoretical at 1.0 MPa. Bore 50 mm, stroke 225 mm trimmed within a 10 mm extend window, double-acting with variable cushioning at each end, 30-800 mm/s, 1/4 in. ports, M14x1.5 rod thread.
The riveted stainless tube plus the 20 um hard-chrome plating on the carbon-steel rod resist mild corrosion and washdown, an edge over painted-steel and plain-aluminium minis in food, beverage or outdoor service.
