Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-75 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 JSIJ80X450-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic unit handles about 1508 N of real work, roughly 128 kg lifted vertically with a 2:1 margin. The hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder, and the G3/8 port feeds a 25 mm rod with M22x1.5 threading.
An external stop screw provides a 75 mm adjustment window, letting you fine-tune the extend stroke down from the 450 mm maximum to 375 mm on site without swapping the cylinder. The retract end remains fixed, and the 29 mm adjustable air cushions at both ends only decelerate the piston near stroke end. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor, and the stop screw sets end position rather than holding the load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-75 Is Used
Divert Gate Tuning
Fine-tunes the extend position of a sorting diverter on site by up to 75 mm to accommodate different package sizes without machining new mounts.
Press Stroke Setup
Adjusts the working stroke of a light-duty assembly press from 450 mm down to 375 mm to handle varying part heights safely.
Pallet Stopper Adjustment
Sets the exact stopping point for pallets on a transfer line, allowing quick changes between pallet formats using the external adjuster.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-75 the Right Cylinder?
When sizing this actuator, 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 you need more power. The 75 mm extend-shortening window is ideal for sharing one spare cylinder across multiple stroke variants or finalizing end positions during machine commissioning. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Since this is a no-magnet SKU, it cannot accept position sensors; add the -S variant for CMSE/DMSE switches. With a 450 mm stroke, always support the load with external guides to prevent rod bending and excessive side loading.
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 JSIJ80X450-75 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore cylinder uses a G3/8 air port.
The 450 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 75 mm on site, giving a usable extend range of 375 to 450 mm. The retract end is fixed, and this mechanism only sets the end position rather than locking the load.
