Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 80mm 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 JSIJ80X80-40
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for applications needing on-site end-position tuning. Its hard-anodized aluminum extruded barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The external adjuster allows you to shorten the extend stroke by up to 40 mm on site, meaning the usable extend range is 40 to 80 mm, while the retract end remains fixed.
This double-acting single-rod actuator handles about 1508 N of real work safely, which equates to roughly 128 kg lifted vertically with a 2:1 margin. It features a 25 mm rod, M22x1.5 rod thread, G3/8 ports, and 29 mm adjustable air cushions at both ends. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; you would need the -S variant for position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-40 Is Used
Press Stroke Tuning
Fine-tune a 40 to 80 mm pressing action on-site to accommodate material thickness variations without swapping the entire actuator.
Divertor Adjustment
Dial in the exact extend length needed to push varying box sizes onto a secondary line, using the external stop screw for rapid changes.
Pallet Stop Gate
Set a precise 60 mm stop position for pallets on a roller conveyor, adjusting the stroke later if pallet dimensions change.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-40 the Right Cylinder?
When sizing this model, the neighboring 63 mm bore offers 1559 N push at 0.5 MPa for lighter loads, while the 100 mm bore steps up to 3927 N if you need significantly more power. The 40 mm adjustable window is ideal for sharing a spare cylinder across slightly different stroke variants or fine-tuning the end position without physically remounting the actuator. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetized SKU, it cannot host a sensor. For any stroke length of 300 mm or more, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ80X80-40 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it delivers 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa.
The 80 mm nominal stroke is the maximum. An external adjuster lets you shorten the extend stroke by up to 40 mm on site, giving a usable extend range of 40 to 80 mm. The retract end is fixed, and this stop mechanism only sets the end position—it does not lock the load.
