Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 225mm 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 JSIJ80X225-30S
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 pneumatics. An external adjuster lets you shorten the forward travel by up to 30 mm, giving a usable range of 195 to 225 mm without swapping the actuator. The hard-anodized aluminum barrel keeps the total length shorter than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which is roughly 128 kg lifted vertically with a 2:1 margin.
This double-acting single-rod unit features a G3/8 port and a 25 mm piston rod with an M22x1.5 thread. The -S suffix means a built-in magnet is present, allowing CMSE or DMSE sensors to drop directly into the side grooves for position detection. Adjustable 29 mm air cushions at both ends absorb end-of-stroke impact. Note that a plain cylinder drifts on air loss; the cushion decelerates but does not lock, so fit an external rod lock for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-30S Is Used
Press Fit Tuning
Dial in the exact 195 to 225 mm extend position on-site to seat bearings without bottoming out the tooling.
Variable Stroke Diversion
Adjust the extend reach up to 30 mm to accommodate different package widths on a sorting line.
Pallet Stop Calibration
Fine-tune the stopping height for mixed pallet sizes using the external adjuster rather than repositioning mounts.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-30S the Right Cylinder?
Size this 80 mm bore against the neighboring 63 mm and 100 mm options. The 63 mm provides 1559 N push at 0.5 MPa, while the 100 mm reaches 3927 N, so choose the 80 mm when you need 2513 N of thrust. The 30 mm adjustable window is ideal for sharing a spare across slightly different stroke variants or fine-tuning the end position on the machine. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because the 225 mm stroke exceeds 300 mm when combined with the bore, ensure external guides support any side loads to prevent rod binding.
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 JSIJ80X225-30S 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 is 513 kgf at 1.0 MPa. This 80 mm bore uses a G3/8 port.
The nominal 225 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable range of 195 to 225 mm. The retract end remains fixed.
