Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 350mm 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 JSIJ63X350-30S
The extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit.
The -30 code means an external stop screw lets you fine-tune the extend end position on-site, shortening the usable stroke from the 350 mm maximum down to 320 mm without swapping the cylinder. The retract end remains fixed. This -S variant carries a built-in piston magnet for CMSE/DMSE switches in the side grooves, and the air port is G3/8.

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 JSIJ63X350-30S Is Used
Press Stroke Tuning
Dial in the exact 320 to 350 mm extend position on-site to accommodate different material thicknesses without changing the actuator.
Transfer Diverters
Fine-tune the extend stop to adjust the diverter gate angle precisely for varying package widths on the line.
Vertical Lift Stops
Shorten the extend stroke by up to 30 mm to set precise vertical lift heights while relying on external guides for the long rod.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-30S the Right Cylinder?
The adjustable stroke is ideal for sharing a single spare across multiple stroke variants or dialing in end positions on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 350 mm stroke is long, always use external guides to prevent rod bending and side loads. The -S magnet supports CMSE/DMSE sensors.
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 JSIJ63X350-30S FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum is 318 kgf at 1.0 MPa. The air port is G3/8.
The 350 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable range of 320 to 350 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
