Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-75S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 175mm 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 JSIJ80X175-75S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to heavy pneumatic tasks. The hard-anodized aluminum barrel is noticeably shorter than a same-bore ISO 15552 unit. A built-in magnet equips it for CMSE/DMSE sensors.
The external stop screw provides a 75 mm adjustment window, letting you fine-tune the usable extend stroke anywhere from 100 to 175 mm without swapping the cylinder. In practice it handles about 1508 N of real work, which translates to lifting roughly 128 kg vertically. Air connects via a G3/8 port, and adjustable cushions decelerate the load at both ends.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-75S Is Used
Press Fit Tuning
Dial in the exact 100 to 175 mm extend position for seating bearings without machining custom spacers.
Variable Transfer Stops
Adjust the extend stop on diverter gates to handle different package sizes on a single line.
Pallet Positioning
Fine-tune the push-off distance for various pallet depths directly at the machine frame.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-75S the Right Cylinder?
When sizing this unit, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter loads, while the 100 mm bore steps up to 3927 N if you need more power. The 75 mm adjustment window is ideal for sharing a single spare across multiple stroke variants or dialing in exact end positions on-site. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports side-groove CMSE/DMSE switches. For any stroke over 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ80X175-75S FAQ
It pushes 2513 N and pulls 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 175 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 100 to 175 mm. The retract end is fixed, and this stop is for positioning only, not load holding.
