Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-100
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 400mm 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 JSIJ80X400-100
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site flexibility to long-stroke automation. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port supplies air, while adjustable cushions at both ends absorb end-of-stroke impact.
The external stop screw provides a 100 mm adjustment window, letting you fine-tune the extend stroke down from the 400 mm maximum to 300 mm without swapping the cylinder. This on-site tuning handles about 1508 N of real work safely, which means roughly 128 kg lifted vertically with a 2:1 margin. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors; the retract end remains fixed, and the stop screw sets position only.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-100 Is Used
Divert Gate Tuning
Dial in the exact extend reach of a sorting diverter on-site using the 100 mm window, accommodating varying package sizes without changing the actuator.
Pallet Stop Adjustment
Fine-tune the stopping position for different pallet depths on a 400 mm stroke, using the external screw to shorten the extend reach as needed.
Press Positioning
Set a precise lower pressing height for varying workpieces, shortening the extend stroke from 400 mm down to 300 mm directly at the machine.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-100 the Right Cylinder?
When sizing this unit, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter loads, whereas stepping up to the 100 mm bore yields 3927 N for heavier demands. The 100 mm extend-shortening window is ideal when you need to share a spare cylinder across slightly different stroke variants or dial in a final end position on the machine. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke is long, always use an external guide rail to prevent rod bending under side loads. Remember that a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ80X400-100 FAQ
This 80 mm bore cylinder uses a G3/8 port and generates 2513 N push and 2268 N pull at 0.5 MPa. 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 nominal 400 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 300-400 mm. The retract end is fixed, and this mechanism sets end position only; it does not lock the load.
