Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 700mm 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 JSIJ80X700-40
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder offers a 700 mm extend stroke with a 40 mm on-site shortening window. The external stop screw lets you fine-tune the end position down to 660 mm without swapping the actuator, while the retract end remains fixed. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. The extruded hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 cylinder.
Air connects via a G3/8 port, driving the 25 mm single rod at 30-800 mm/s with 29 mm adjustable air cushions at both ends. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Note that the adjustable stop sets the stroke endpoint but is not a load lock; the cushion only decelerates the piston. To hold a load securely on air loss, you must fit an external rod lock or a pilot-operated check valve.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40 Is Used
Long-Reach Diversion
Pushes heavy pallets across a wide transfer section, using the 40 mm adjuster to dial in the exact contact point without repositioning the cylinder.
Multi-Tier Lowering
Lowers fixtures onto varying stack heights, relying on the 660-700 mm usable extend window to accommodate different pallet thicknesses on the fly.
Adjustable Stopper Gate
Acts as a heavy-duty end-stop on a packaging line, fine-tuning the 700 mm extension to handle different box sizes while absorbing kinetic energy via the 29 mm cushions.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40 the Right Cylinder?
When sizing this 80 mm bore actuator, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927 N, giving you a clear force gradient for tuning your payload. The 40 mm adjustable window is highly useful for sharing a single spare cylinder across multiple machines that need slightly different extend lengths, letting you dial in the exact endpoint on the floor. You can mount this JIS body using FA, LB, TC, TCM1, or TCM2 brackets. Because the 700 mm stroke is quite long, you must support the load with an external guide to prevent rod bending and excessive side loading. Remember that this non-magnet version cannot host position 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 JSIJ80X700-40 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 maximum force is 513 kgf at 1.0 MPa. It uses a G3/8 air port and features a 25 mm rod with an M22x1.5 thread.
The 700 mm nominal stroke is the maximum extension. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 660 to 700 mm. The retract end is fixed, and this stop mechanism only sets the end position rather than locking the load.
