Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-40
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-40 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 JSIJ63X350-40
The hard-anodized aluminum barrel keeps the total length shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing power.
The -40 code defines an external adjuster window that lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 310 to 350 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder, and the G3/8 port matches the 63 mm bore standard. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without upgrading to the -S variant.

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 JSIJ63X350-40 Is Used
Transfer Line Diverter
Dial in the 310 to 350 mm extend reach on-site to push varying pallet sizes off a main conveyor belt without changing the actuator body.
Vertical Lift Gate
Lifts a 79 kg safety gate using the 0.5 MPa push force, relying on the 29 mm adjustable air cushions to decelerate the load smoothly at the top.
Carton Flap Folder
Fine-tune the extend end position by up to 40 mm to accommodate different carton depths on the fly, ensuring precise folding without mechanical shims.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-40 the Right Cylinder?
The 40 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in final end positions during commissioning. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 350 mm, always use an external guide rail to prevent rod bending and absorb side loads. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ63X350-40 FAQ
It features a 63 mm bore, a 20 mm rod, a G3/8 port, and 29 mm adjustable air cushions at both ends.
The external adjuster allows you to shorten the extend stroke by up to 40 mm on-site, providing a usable extend range of 310 to 350 mm while the nominal 350 mm remains the maximum. The retract end is fixed, and this mechanism only sets the end position; it does not lock or hold the load.
