Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-40
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X160-40 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 160mm 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 JSIJ63X160-40
You get a usable extend range of 120-160 mm from the 160 mm nominal maximum, while the retract end stays fixed. The hard-anodized aluminum extruded barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. Air connects via a G3/8 port.
This double-acting double-rod actuator runs at 30-800 mm/s with 29 mm adjustable air cushions at both ends. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor. The external stop screw sets your end position precisely but does not lock the load; if you need to hold a vertical load against air loss, add an external rod lock or pilot-operated check valve.

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

| 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 JSIJ63X160-40 Is Used
End-Stop Tuning for Clamping
Dial in the exact 120-160 mm clamp reach on a machining fixture using the external adjuster, accommodating varied part thicknesses without remounting the actuator.
Variable Length Diverting
Shorten the extend stroke by up to 40 mm on a sorting pusher to handle different carton sizes on the fly while maintaining the full retract distance.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-40 the Right Cylinder?
The -40 mm adjustable window is ideal for fine-tuning the extend end position on site without swapping cylinders, letting you standardize spares across slightly different stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. For any stroke at or over 300 mm, guide the load externally to prevent side-load wear on the rod seals. To add position sensing, you must select the -S magnet version for CMSE/DMSE switches.
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 JSIJ63X160-40 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
The 160 mm nominal stroke is the maximum extend travel. The external adjuster lets you shorten the extend stroke on site by up to 40 mm, giving a usable extend range of 120-160 mm. The retract end remains fixed. This mechanism sets the end position but does not hold the load.
