Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-10S 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 JSIJ63X225-10S
The hard-anodized aluminum extruded body makes it shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the double-acting double rod, and the integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for position feedback.
The external stop screw provides a 10 mm adjustable window, letting you fine-tune the extend end position from 215 to 225 mm without changing the mount. The retract end remains fixed. Note that the adjustable stop sets the end position but does not lock the load; a separate rod lock or pilot-operated check valve is required to hold a load on air loss.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
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 JSIJ63X225-10S Is Used
End-Stop Calibration
Fine-tune the extend position by up to 10 mm on-site to dial in the exact clamping depth without swapping the cylinder.
Divert Gate Positioning
Adjusts the extend endpoint precisely to deflect varying package sizes on a sorting line while using the fixed retract end.
Pallet Stop Tuning
Sets the exact stop height for different pallet configurations, using the 225 mm stroke with a 10 mm on-site adjustment window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-10S the Right Cylinder?
The 10 mm extend adjustment window is ideal for sharing a spare cylinder across slightly different stroke variants or fine-tuning end positions on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The built-in -S magnet supports CMSE/DMSE switches for electronic or reed sensing. Because the 225 mm stroke exceeds 300 mm, ensure you use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ63X225-10S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod.
An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 215 to 225 mm. The nominal 225 mm stroke is the maximum. The retract end is fixed, and this mechanism only sets the end position rather than holding the load.
