Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X25-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X25-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 25mm 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 MACJ63X25-10S
Short stroke, serious muscle: the MACJ63X25-10S is a double-acting AirTAC MA round-body mini cylinder, 63 mm bore and 25 mm stroke, with an external stop screw that trims the extend stroke anywhere inside a 10 mm window. A variable air cushion at both ends lets you raise speed or load without hammering the covers. At 0.5 MPa the bore pushes 1558 N and retracts with 1457 N, running on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The stainless barrel is riveted to aluminium covers with a hard-chrome plated rod, so mild corrosion and washdown in food or outdoor cells are non-issues where painted minis would rust. Every unit ships with the magnet built in, so CMSG, DMSG or EMSG switches mount with no special-order piston. For sizing, keep real work near 935 N at 0.5 MPa; that also means it lifts roughly 79 kg vertically on a 2:1 margin.

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 MACJ63X25-10S Is Used
Mold ejector pin
Kicks cooled caps or housings off an injection mold core in one short 25 mm hit, with the 10 mm window letting the toolmaker set eject height without shims.
Die staking punch
Swages thin steel brackets at up to 2181 N on 0.7 MPa, replacing a small hydraulic press on the assembly line.
Small-part press fit
Presses bushings into machined housings on an assembly bench; the cushioned end stop protects delicate bores at high cycle rates.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X25-10S the Right Cylinder?
The 63 mm bore tops the MA range, so downsize to the 50 mm bore (981 N push at 0.5 MPa) if the load is under about 500 N. The 10 mm trim window fits dies and fixtures where the extend stop is final-set on the machine. Bolt it down with the FA flange or LB foot; I and Y rod knuckles absorb small misalignment. Keep in mind the stop screw only sets stroke length - it is not a position lock, and the rod can drift if air pressure drops.
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 MACJ63X25-10S FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N. At 0.7 MPa push reaches 2181.0 N (pull 2040.3 N), and the theoretical maximum at 1.0 MPa is 317.7 kgf. Air ports are 1/4" and the male rod thread is M14x1.5.
The stainless tube, riveted covers and 20 um hard-chrome rod resist corrosion and survive washdown, while the dual variable cushions let you run 30-800 mm/s with quiet, low-shock stops. The built-in magnet works with CMSG, DMSG and EMSG switches out of the box.
