Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm 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 JSIJ80X800-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder manages long 800 mm reaches while staying shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light, and the G3/8 port feeds a 25 mm rod to handle about 1508 N of real work, roughly 128 kg lifted vertically with a 2:1 margin.
The external stop screw provides a 50 mm on-site extend-shortening window, letting you fine-tune the end position down to a 750 mm usable stroke without swapping the cylinder. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor. Note that the adjustable cushion only decelerates the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50 Is Used
Long-Reach Transfer
Pushes heavy pallets along a conveyor with a 750 to 800 mm extend stroke, using the adjuster to match exact stop distances.
Material Lowering
Lowers fixtures with a 50 mm end-position window for soft landing calibration, though an external check valve is needed to hold the load.
Press Ejection
Ejects wide parts from a press bed where the compact JIS profile saves machine space compared to standard ISO 15552 builds.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50 the Right Cylinder?
Size this 80 mm bore against the 63 mm option, which offers 1559 N push at 0.5 MPa, or the 100 mm class delivering 3927 N if you need more thrust. The 50 mm adjuster is ideal for sharing one spare across multiple stroke variants or dialing in exact end positions on-site. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. With an 800 mm stroke, you must support the rod against bending using external guides to prevent side-load damage.
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 JSIJ80X800-50 FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical max force is 513 kgf at 1.0 MPa, and the air port is G3/8.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a 750 to 800 mm usable range. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
