Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-50 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 JSIJ63X450-50
Its hard-anodized extruded aluminum barrel omits tie rods entirely, making the overall body shorter and more streamlined than a same-bore ISO 15552 unit. The G3/8 port feeds a double-acting double-rod system rated for 30-800 mm/s speeds.
The external adjuster lets you trim the extend stroke by up to 50 mm on site, yielding a usable 400-450 mm end-position window while the retract end stays fixed. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 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 JSIJ63X450-50 Is Used
Transfer Push-Off Tuning
Trim the 450 mm extend stroke down by 50 mm on-site to perfectly strike a product diverter on a conveyor without remounting the actuator.
Press End-Position Dial-In
Use the adjustable window to set a precise 400 mm lower end position for a light assembly press, accommodating varying material thicknesses.
Pallet Stopper Adjustment
Dial the external stop screw to fine-tune the stopping face for mixed pallet sizes in a compact handling cell where JIS profile space is tight.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-50 the Right Cylinder?
The adjustable stroke is highly useful when you need to fine-tune the extend endpoint on the machine or want a single shared spare across slightly different stroke variants. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. Since the 450 mm stroke is long, always use an external guide to prevent rod bending and side-load wear.
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 JSIJ63X450-50 FAQ
The nominal 450 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on site, giving a usable range of 400-450 mm. The retract end is fixed, and this stop only sets position—it does not lock the load.
