Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X300-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X300-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 300mm 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 JSIJ63X300-100
The external adjuster lets you shorten the 300 mm nominal extend stroke by up to 100 mm, giving a usable range of 200-300 mm for fine-tuning the end position without swapping the actuator. Its extruded hard-anodized aluminium barrel is notably shorter than an ISO 15552 cylinder of the same bore.
It uses a G3/8 port, an M18x1.5 rod thread, and 29 mm adjustable air cushions at both ends. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor. Note that the adjuster sets end position only; it is not a load lock, so use an external rod lock or pilot-operated check valve to hold a load on air loss.

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 JSIJ63X300-100 Is Used
Press Stroke Tuning
Dial in the exact 200 to 300 mm extend position on a light stamping or press line without machining new hard stops.
Transfer Diverter
Adjust the extend reach on the fly to route different carton widths through a sorting station.
Pallet Stopper Gate
Set the precise stop height for mixed pallet sizes and readjust quickly when the line changes over.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X300-100 the Right Cylinder?
The -100 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialling in a precise end position on the machine. Mounting choices include FA, LB, TC, TCM1, and TCM2. For this 300 mm stroke, always support the load with external guides 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 JSIJ63X300-100 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and operates at speeds of 30-800 mm/s.
The 300 mm nominal stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 200-300 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
