Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-20
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 500mm 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 JSIJ80X500-20
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic unit brings on-site flexibility to long-stroke automation. The hard-anodized aluminum profile barrel keeps the overall body shorter than a same-bore ISO 15552 cylinder. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
The external adjuster allows you to shorten the extend stroke by up to 20 mm directly at the machine, giving a usable range of 480-500 mm without swapping the cylinder. Air connections use a G3/8 port. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-20 Is Used
Transfer Push-off
Fine-tunes the 500 mm extend position by up to 20 mm to push varying carton sizes off a belt without repositioning the cylinder mount.
Press Lowering
Regulates the downstroke end point on a light assembly press, letting operators dial in the exact 480-500 mm stopping height on site.
Pallet Stopper
Adjusts the extend limit to act as a physical stop for different pallet depths while benefiting from the 2513 N push force at 0.5 MPa.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-20 the Right Cylinder?
When sizing this unit, the neighboring 63 mm bore offers 1559 N push at 0.5 MPa for lighter duties, while the 100 mm bore steps up to 3927 N if your application demands more power. The 20 mm adjustable window is ideal for fine-tuning the extended end position across multiple stations or sharing a spare cylinder between stroke variants. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Since the stroke is 500 mm, always use an external guide to prevent rod bending and absorb side loads. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 JSIJ80X500-20 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 air port and features a 29 mm adjustable air cushion at both ends.
The nominal 500 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 20 mm on site, providing a usable range of 480-500 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
