Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50 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 JSIJ80X450-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. Its extruded hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds the 25 mm rod to generate 2268 N of pull force on the retract stroke.
The external stop screw lets you trim the extend stroke on-site by up to 50 mm, dropping the usable travel from the 450 mm maximum down to 400 mm without swapping the cylinder. This on-site tuning means it handles about 1508 N of real work safely, roughly 128 kg lifted vertically with a 2:1 margin. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor; you would need the -S variant for position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50 Is Used
Transfer Diverter
Fine-tunes the 450 mm extend stroke by up to 50 mm to set the exact push distance for diverting heavy pallets between conveyor lanes.
Vertical Lift Gate
Lifts materials safely using its 2513 N push capacity, with the adjustable end-stop allowing precise gate positioning without re-mounting hardware.
Press Clamping
Clamps large workpieces where the 50 mm on-site adjust window dials in the exact contact position to compensate for material thickness variations.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50 the Right Cylinder?
When sizing, the adjacent 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N, so the 80 mm sits squarely in the mid-heavy range. The adjustable stroke is ideal when you need to fine-tune an end position across multiple stations or keep a shared spare for slightly different travel needs. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Since the 450 mm stroke creates a long lever arm, always use an external guide to prevent rod bending and side loads. Remember that the plain air cushion only decelerates the piston; it will not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for vertical safety.
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 JSIJ80X450-50 FAQ
This 80 mm bore cylinder uses a G3/8 air port and a 25 mm rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, or 3518 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 450 mm stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 400 to 450 mm. The retract end remains fixed, and the stop screw sets the end position rather than locking the load.
