Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 225mm 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 JSIJ63X225-100
Its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port and M18x1.5 rod thread keep pneumatic and mounting integration straightforward.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 125 to 225 mm without swapping the cylinder. The retract end remains fixed, and the 29 mm adjustable air cushions at both ends only decelerate the piston near stroke end.

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 JSIJ63X225-100 Is Used
Transfer Push-Off Tuning
Dial in the exact push-off distance on a conveyor diverter by shortening the extend stroke on-site by up to 100 mm to match varying package sizes.
Clamp Position Adjustment
Fine-tune the clamping end position on a machining fixture without machining new spacers, using the external stop screw to hit the exact 125 to 225 mm forward travel.
Pallet Stopper Calibration
Set the precise stopping height for incoming pallets on a packaging line, adjusting the extend stroke on the fly to accommodate different pallet thicknesses.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-100 the Right Cylinder?
The 100 mm adjuster window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the end position during machine commissioning. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Since this SKU lacks the -S suffix, it cannot take a magnetic switch; order the -S variant for CMSE/DMSE sensors. For this 225 mm stroke, ensure external guide rails are used to prevent excessive side-loading on the rod.
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 JSIJ63X225-100 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The nominal 225 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 125 to 225 mm. The retract end is fixed, and this stop only sets the end position; it does not lock the load.
