Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75 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 JSIJ80X800-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder shortens on-site from its 800 mm maximum extend stroke down to 725 mm via a 75 mm external adjuster window. The retract end remains fixed. Built with an extruded hard-anodized aluminum barrel, the body is noticeably more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
This double-acting single-rod actuator uses a G3/8 port and a 25 mm piston rod with an M22x1.5 thread. Adjustable 29 mm air cushions at both ends manage end-of-stroke deceleration. Because this SKU lacks a magnet, it cannot take CMSE or DMSE sensors. The cushion only slows the piston near the end of travel; it does not lock the load, so fit an external rod lock or pilot-operated check valve if you need to hold a vertical load against air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75 Is Used
Transfer Line Diverter
Pushes pallets onto a secondary conveyor and uses the 75 mm adjuster to dial in the exact push distance for varying product sizes without changing the cylinder.
Long-Press Platen
Drives an 800 mm platen down into a forming press, relying on the external stop screw to set the precise bottom dead center for different material thicknesses.
High-Bay Extractor
Reaches deep into storage racks to extract totes, using the adjustable extend window to accommodate different shelf depths while maintaining a compact JIS footprint.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75 the Right Cylinder?
When sizing this 80 mm bore actuator, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N. The JSIJ adjustable-stroke mechanism is ideal when you need to fine-tune the extend end position without physically swapping cylinders, or when you want a shared spare across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For this 800 mm stroke, you must support the rod against bending and use external guides to prevent side-loading damage. To add position sensing, you must select the -S magnet version for CMSE or DMSE switches, as this base SKU cannot accept them.
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 JSIJ80X800-75 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. The air port size is G3/8.
The 800 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 725 to 800 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
