Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-20S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 500mm 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 JSIJ63X500-20S
The external adjuster lets you shorten the forward travel by up to 20 mm, giving a usable range of 480 to 500 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port and M18x1.5 rod thread handle the air and mounting demands of mid-range automation.
Built for position feedback, the -S suffix adds a piston magnet for CMSE/DMSE switches that clip directly into the side grooves. The retract end remains fixed, and while the adjustable air cushions absorb end-of-stroke impact, a plain cylinder cannot hold a load on air loss—use an external rod lock or pilot-operated check valve for vertical safety.

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 JSIJ63X500-20S Is Used
Transfer Line Diverter
Fine-tune the 480 to 500 mm extend position to match varying pallet widths on the fly without re-mounting the actuator.
Press Sub-assembly
Dials in the exact 20 mm contact approach window for delicate part seating before the full 500 mm stroke completes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-20S the Right Cylinder?
The 20 mm adjustable window is highly useful for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because the 500 mm stroke creates a long lever arm, always guide the load externally to prevent rod bending and side-load damage. The built-in magnet supports CMSE/DMSE sensors for precise positioning.
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 JSIJ63X500-20S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. This 63 mm bore model uses a G3/8 air port.
The nominal 500 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable extend range of 480 to 500 mm. The retract end position remains fixed, and the cushion only decelerates the piston rather than locking the load.
