Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm 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 JSIJ80X800-75S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder keeps your footprint tight and is noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum extruded barrel contains no tie rods, and the G3/8 air port matches the bore size. Because it carries the -S suffix, a built-in piston magnet is present for drop-in CMSE or DMSE reed and electronic switches.
The external stop screw provides a 75 mm adjustable window, meaning you can fine-tune the extend stroke anywhere from 725 mm up to the 800 mm maximum right on the floor without swapping the cylinder. The retract end remains fixed. This adjuster sets the end position and decelerates the load via the 29 mm cushions, but it is not a lock. It handles about 1508 N of real work safely, which is roughly 128 kg lifted vertically with a 2:1 margin.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75S Is Used
Transfer Line Diverter
Fine-tune the 725 to 800 mm extend reach on-site to push pallets of varying widths off a main conveyor belt without re-mounting the actuator.
Vertical Material Lift
Lifts roughly 128 kg vertically using the 2513 N push force, with the external adjuster allowing precise upper-stop positioning for different shelf heights.
Press Pin Insertion
Dial in the exact 725 mm extend endpoint to seat pins without bottoming out, relying on the 29 mm adjustable air cushions to decelerate the stroke.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-75S the Right Cylinder?
When sizing this unit, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to the 100 mm bore provides 3927 N. The 80 mm bore sits comfortably in the middle for medium-duty tasks. The 75 mm extend-shortening window is highly useful when you need to synchronize end positions across multiple stations or want a single spare cylinder to cover several stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 800 mm stroke is long, always use external guides to prevent rod bending and account for side loads.
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 JSIJ80X800-75S FAQ
This 80 mm bore cylinder features a G3/8 air port and a 25 mm piston rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum force of 513 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 725 to 800 mm where 800 mm is the maximum. The retract end is fixed. This mechanism sets the end position and is not a load lock.
