Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-100S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-100S 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 JSIJ63X450-100S
A built-in magnet (-S) allows CMSE/DMSE sensors to drop directly into the side grooves for precise position detection. The hard-anodized aluminum extruded barrel keeps the total envelope more compact than a same-bore ISO 15552 unit. Air connects via a G3/8 port.
The external stop screw provides a 100 mm adjustment window, letting you tune the usable extend stroke anywhere from 350 mm up to the 450 mm maximum without changing the cylinder itself, while the retract end remains fixed. Note that the adjustable air cushions only decelerate the piston near the ends; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.

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 JSIJ63X450-100S Is Used
Sorter Diverter Tuning
Fine-tune the extend stop in the field to perfectly match varying package sizes on a sorting line without swapping out the entire actuator.
Press Pinion Depth
Adjust the 100 mm window to set precise lower end positions for a pressing operation, ensuring accurate insertion depth across different material batches.
Multi-Height Pallet Stop
Use the external adjuster to quickly change the extend stroke limit for different pallet heights, maximizing spare part commonality in a packaging cell.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-100S the Right Cylinder?
The -100 mm adjustable window is highly useful when you need to share a spare cylinder across slightly different stroke variants or fine-tune the end position on-site. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke creates leverage, always use an external guide to prevent rod bending and side loads. The -S magnet supports reed or electronic 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 JSIJ63X450-100S FAQ
The -100 indicates a 100 mm external adjuster window. You can shorten the extend stroke on-site from the 450 mm maximum down to 350 mm, while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
