Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-100 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 JSIJ63X450-100
Its extruded hard-anodized aluminium barrel is noticeably shorter than a same-bore ISO 15552 unit, saving machine footprint. The G3/8 port feeds the 20 mm rod for smooth 30-800 mm/s operation.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, giving a usable range of 350-450 mm from the 450 mm maximum. You can fine-tune the end position without swapping the cylinder. This plain SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 JSIJ63X450-100 Is Used
Transfer Push-Off
Pushes parts off a belt at 450 mm, with the 100 mm adjuster used to dial in the exact reject position for different product lengths.
Pallet Stopper Gate
Acts as a 63 mm bore pallet stop where the extend stroke is fine-tuned on-site to 380 mm to match varying pallet depths.
Vertical Press Head
Provides 1559 N of downward thrust for light pressing, using the external adjuster to set a precise 350 mm lower limit.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-100 the Right Cylinder?
The 100 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or trim the end position on-site. Mounting options include FA, LB, TC, TCM1 and TCM2. Because the 450 mm stroke invites rod bending, always use an external guide to absorb side loads. This no-magnet version cannot host position sensors; specify the -S variant for 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 JSIJ63X450-100 FAQ
This 63 mm bore cylinder has a G3/8 port and a 20 mm rod.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm. The nominal 450 mm stroke is the maximum, so the usable extend range is 350-450 mm. The retract end is fixed. Note that this stop only sets position; it does not lock the load, so use a pilot-operated check valve for holding.
