Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10 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 JSIJ80X450-10
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings compact power to long-stroke tasks. Its hard-anodized extruded aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit, while the G3/8 port feeds a 25 mm piston rod. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
The external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 440-450 mm without changing the cylinder itself; the retract end remains fixed. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor. Note that the 29 mm adjustable air cushions only decelerate the load near stroke ends, so fit an external rod lock or pilot-operated check valve if you need to hold a load against gravity.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10 Is Used
Transfer Push-Off
Pushes heavy pallets off a conveyor line, using the 10 mm adjuster to dial in the exact push-off distance for varying box widths.
Press Down Stop
Lower a 128 kg tooling head in a vertical press, relying on the adjustable stop to set the precise lower dead center without shims.
Divert Arm Actuation
Drives a heavy sorting divert arm on a packaging line, making on-site end-position tweaks easy to accommodate new product sizes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-10 the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter loads, while the 100 mm bore jumps to 3927 N if you need more thrust. The 10 mm adjustable window is ideal for sharing one spare across slight stroke variants or fine-tuning a final end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. With a 450 mm stroke, you must support the load with an external guide to prevent rod bending and excessive side loading. This non-magnet version cannot accept a sensor; choose the -S variant for CMSE or DMSE switches.
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 JSIJ80X450-10 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 max force is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod with an M22x1.5 thread, and 29 mm adjustable cushions at both ends.
The nominal 450 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable extend range of 440-450 mm. The retract end is fixed, and this stop mechanism only sets the end position rather than locking the load.
