Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-10S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-10S 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 JSIJ63X500-10S
The external adjuster lets you shorten the extend stroke by up to 10 mm, giving a usable range of 490-500 mm without swapping the actuator. The retract end remains fixed. The hard-anodized aluminum extruded barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 cylinder.
Because this SKU carries the -S suffix, it includes a built-in piston magnet for CMSE/DMSE switches that mount directly into the side sensor grooves. Pneumatic connections use a G3/8 port, while a 29 mm adjustable air cushion at each end manages end-of-stroke deceleration. Note that a plain cylinder does not hold load on air loss; the cushion only decelerates, so fit an external rod lock or pilot-operated check valve if you need true load holding.

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 JSIJ63X500-10S Is Used
Transfer Line Diverter
Fine-tune the 490-500 mm extend position by up to 10 mm on-site to perfectly align a diverter gate without machining new hard stops.
Long-Reach Part Forming
Deploys the 500 mm stroke to reach into a press, relying on the 29 mm cushions to decelerate the tooling before the final position is dialed in.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-10S the Right Cylinder?
The 10 mm adjustable window is highly useful when you need to fine-tune a final end position across multiple stations or want a shared spare for slightly different stroke variants. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. Because the 500 mm stroke is long, always guide the load externally to prevent rod bending and side-load damage.
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 JSIJ63X500-10S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod with an M18x1.5 thread.
The nominal 500 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable extend range of 490-500 mm. The retract end is fixed, and this stop only sets position, it does not lock the load.
