Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 450mm 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 JSIJ80X450-10S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to heavy-duty automation. The external adjuster allows you to shorten the extend stroke by up to 10 mm, giving a usable range of 440 to 450 mm without changing the cylinder itself. This fine-tuning is ideal for dialing in exact end positions. The hard-anodized aluminum extruded barrel keeps the overall body shorter and more compact than an equivalent ISO 15552 cylinder, while the G3/8 port handles the required air volume.
With a safe working load around 1508 N, it handles roughly 128 kg lifted vertically with a 2:1 margin. The built-in magnet (-S) supports CMSE/DMSE sensors that drop directly into the side grooves for precise position detection. Remember that the adjustable stop sets the end position but does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a load securely against air loss. Because the 450 mm stroke introduces side-load risks, external guides are recommended to prevent rod bending.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10S Is Used
Press Stroke Tuning
Dial in the exact 440 to 450 mm extend position on-site to accommodate different material thicknesses in a light-duty press without swapping the cylinder.
Transfer Line Diversion
Adjust the extend stop by up to 10 mm to perfectly align a diverting arm with varying product widths on a high-throughput packaging conveyor.
Pallet Stopper Calibration
Fine-tune the end position of a pallet stop gate by a few millimeters to compensate for mechanical wear or varying pallet tolerances over time.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10S the Right Cylinder?
When sizing this 80 mm bore model, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, letting you step up or down to match your exact force requirements. The 10 mm adjustable window is particularly useful when you want a shared spare across slightly different stroke variants or need to fine-tune the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means the piston magnet is already included for CMSE/DMSE switches. For this 450 mm stroke, always factor in external guides to absorb side loads and prevent rod bending.
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 JSIJ80X450-10S FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa, and pushes 3518 N while pulling 3175 N at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa. It uses a G3/8 air port and features a 25 mm piston rod with an M22x1.5 rod-end thread.
The nominal 450 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, providing a usable range of 440 to 450 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
