Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm 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 MACJ63X225-10S
Fine tuning is the point of the MACJ63X225-10S: the same 63 mm bore double-acting cushioned action as the rest of the MACJ line, but a compact 10 mm window for trimming the extend stroke. That is enough to dial in an end position to within millimetres while the variable air cushion at both ends soaks up the 1558 N push at 0.5 MPa. The riveted stainless round barrel and 20 um hard-chrome rod laugh at the condensation that corrodes ordinary painted-steel minis.
Plan the job around about 935 N of usable push at 0.5 MPa; expressed as lifting, that is roughly 79 kg vertical with a 2:1 safety margin built in. A standard magnet means the unit is sensor-ready out of the box with CMSG, DMSG or EMSG switches, no special piston to 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X225-10S Is Used
Test rig load positioning
Lab rigs benefit from the fine 10 mm trim: set the exact end position once, then let the variable cushion repeat smooth stops cycle after cycle.
Register stop on a rewind machine
Nudging web rolls to a precise register point needs only millimetres of adjustment, which the 10 mm window delivers while cushions protect the rolls.
Clamp fixture with fine stroke trim
Fixturing aluminum castings calls for about 935 N of clamp-side push at 0.5 MPa; the short trim window lets machinists tune clamp travel per part.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-10S the Right Cylinder?
If 1558 N is oversized for the job, bore 50 pushes 981 N at 0.5 MPa; there is no MA bore above 63 mm. Treat the 10 mm adjuster as an extend-side end stop only - it will not hold a load if air pressure drops. Choose FA or LB mounting and I or Y rod knuckles as the job demands, and remember the magnet is already in the piston for sensor work. A 225 mm unsupported stroke deserves external guiding whenever side loads are present.
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 MACJ63X225-10S FAQ
It pushes 1558 N and pulls 1457 N at 0.5 MPa. Raise pressure to 0.7 MPa and the figures become 2181 N push and 2040 N pull, with a theoretical ceiling of 317.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, and the extend stroke can be shortened anywhere within the 10 mm window.
FA flange and LB foot brackets are the standard mountings, with I and Y rod knuckles available for linkage work. For ordering, just specify the bore, the 225 mm stroke, the 10 mm window and the thread choice - PT (blank), G or NPT - since adjustable versions drop the separate back-cover code.
