Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10
The external stop screw provides a 10 mm shortening window, letting you trim the usable extend stroke down to 215 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit.
This double-acting double-rod unit features a 20 mm piston rod, an M18x1.5 rod-end thread, and a G3/8 air port. Adjustable air cushions of 29 mm at each end absorb impact energy. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors. Furthermore, the cushion only decelerates the piston; it does not hold the load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict positioning.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10 Is Used
End-Position Trimming
Dial in the exact extend reach on a machining fixture by turning the external stop screw to shave up to 10 mm off the 225 mm nominal stroke.
Transfer Pusher Adjustment
Accommodate varying product sizes on a line by tweaking the extend window on-site, avoiding the need to stock multiple fixed-stroke actuators.
Compact Divert Arm
Fit a robust 1559 N diverter into a tight machine envelope thanks to the short JIS profile barrel that saves space over standard ISO 15552 bodies.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10 the Right Cylinder?
The 10 mm adjustable window is highly useful when you need to share one spare cylinder across several stroke variants or fine-tune a final end position on the machine. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnetised SKU, you cannot fit position sensors; choose the -S variant if you require CMSE or DMSE switches. For a 225 mm stroke, ensure adequate side-load guidance to prevent premature seal wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. This 63 mm bore unit uses a G3/8 air port.
The nominal stroke is 225 mm, which is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 215 to 225 mm. The retract end is fixed, and this stop mechanism is for position tuning only, not for holding a load.
