Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-75S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 450mm 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 JSIJ63X450-75S
The hard-anodized aluminum barrel skips external rods for a clean exterior, while the G3/8 port feeds the 20 mm rod to generate 1402 N of pull force. A built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
The external adjuster allows you to trim the extend stroke by up to 75 mm on-site, giving a usable forward travel of 375 to 450 mm without swapping the cylinder. This on-site tuning means you can fine-tune the end position to match machine wear or shared spare requirements, while the retract end remains fixed.

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 JSIJ63X450-75S Is Used
Divert Gate Tuning
Dial in the 375 to 450 mm extend reach on a sorting line by turning the external stop screw to match varying package sizes without replacing the actuator.
Pallet Stopper Gate
Fine-tune the stopping position of a pallet flow lane by shortening the extend stroke up to 75 mm, ensuring precise alignment for downstream wrapping.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-75S the Right Cylinder?
The 75 mm adjuster window is ideal for machines needing precise end-position tuning after installation or sharing a single spare across multiple stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the 450 mm stroke is long, always support the load with an external guide to prevent rod bending and side-load damage. The -S suffix ensures you have the magnet required for CMSE/DMSE sensors.
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 JSIJ63X450-75S FAQ
This 63 mm bore cylinder features a G3/8 air port and a 20 mm rod with an M18x1.5 thread.
The external stop screw lets you shorten the extend stroke by up to 75 mm on-site, providing a usable forward travel range of 375 to 450 mm where 450 mm is the maximum. The retract end is fixed, and this mechanism sets the end position rather than locking the load.
