Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 25mm 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 JSIJ80X25-10S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for applications demanding exact end-position tuning. The external stop screw provides a 10 mm adjustable window, letting you shorten the extend stroke down to 15 mm on-site without swapping the actuator. Because the nominal 25 mm stroke is the maximum, you can dial in the precise travel right at the machine. This translates to a safe working load of about 1508 N, or roughly 128 kg lifted vertically with a 2:1 margin. The hard-anodized aluminum barrel uses no tie rods, making the body shorter and more compact than a same-bore ISO 15552 cylinder.
This -S variant includes a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Pneumatic connections use a G3/8 port, and adjustable air cushions of 29 mm at each end absorb impact energy. Note that a plain cylinder does not hold load on air loss; the cushion only decelerates near the end of travel. For a held load, you must fit an external rod lock or a pilot-operated check valve.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10S Is Used
Short-Stroke Clamping
Dial in the exact clamping travel between 15 and 25 mm on-site to accommodate varying material thicknesses without changing the cylinder.
Precise Pressing
Use the external stop screw to set a precise lower dead center for light pressing tasks, ensuring consistent contact force.
End-Stop Positioning
Fine-tune the extend endpoint on a conveyor divert mechanism to handle different product sizes quickly and reliably.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10S the Right Cylinder?
When sizing this actuator, the 80 mm bore sits between the 63 mm class (1559 N push at 0.5 MPa) and the 100 mm class (3927 N push at 0.5 MPa), giving you 3518 N at 0.7 MPa if you need extra force. The 10 mm adjustable window is ideal when you want a shared spare across slight stroke variants or need to fine-tune a clamping distance on-site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE sensors for position feedback. Even at this short 25 mm stroke, always guide the load to prevent side-load binding.
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 JSIJ80X25-10S 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 port.
The 25 mm nominal stroke is the maximum extend travel. The external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 15 to 25 mm. The retract end is fixed, and the stop sets position only—it does not lock the load.
