Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50S 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 JSIJ80X80-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic actuator brings on-site flexibility to demanding operations. The external stop screw provides a 50 mm adjustment window, allowing you to shorten the extend stroke from the 80 mm maximum down to 30 mm without swapping the cylinder. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically.
Built as a JIS-standard profile cylinder, the hard-anodized aluminium body is noticeably shorter than a same-bore ISO 15552 unit. This -S variant includes a piston magnet for CMSE/DMSE sensors that mount directly into the side grooves. The G3/8 port feeds the 29 mm adjustable air cushions at both ends, ensuring smooth deceleration across the 30-800 mm/s speed range.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50S Is Used
Press Fit Tuning
Dial in the exact 30 to 80 mm extend position for seating bearings without machining custom spacers or changing actuators.
Variable Transfer Stops
Adjust the stroke stop on the line to handle mixed carton sizes on the fly, using the 50 mm window to reposition the diverter.
Pallet Positioning
Shift the extend end-point to interface with different pallet depths, relying on the 2513 N thrust to push loads firmly into place.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50S the Right Cylinder?
When sizing this 80 mm bore, the neighbouring 63 mm offers 1559 N push at 0.5 MPa, while the 100 mm steps up to 3927 N if you need heavier thrust. The 50 mm extend-shortening window is ideal for fine-tuning end positions on-site or sharing a single spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this -S model has the built-in magnet, it fully supports CMSE/DMSE reed and electronic switches. For any stroke length over 300 mm, 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 JSIJ80X80-50S 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 uses a G3/8 air port, a 25 mm rod, and features 29 mm adjustable cushions.
The 80 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 30 to 80 mm. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
