Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 350mm 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 JSIJ80X350-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminium extruded barrel keeps the assembly light while housing a 25 mm rod and G3/8 ports. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
The -50 code means an external stop screw lets you shorten the 350 mm extend stroke on-site down to 300 mm for fine end-position tuning, while the retract end stays fixed. The -S suffix adds a built-in piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Remember that the adjustable stop sets position only; it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-50S Is Used
Divert Gate Tuning
Shorten the 350 mm extend stroke by up to 50 mm on-site to perfectly set a divert gate position without machining new stops.
Pallet Stopper Adjustment
Fine-tune the end position of a pallet stopping fence across mixed product sizes using the external adjuster.
Press Head Positioning
Set the exact lower end position for a light press head, utilizing the 2513 N push force at 0.5 MPa.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-50S the Right Cylinder?
Size this 80 mm bore against the neighbouring 63 mm and 100 mm options. The 63 mm gives 1559 N push at 0.5 MPa, whereas the 100 mm reaches 3927 N, so choose the 80 mm when you need 2513 N of thrust. The 50 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions on-site without swapping the cylinder. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 350 mm stroke is long, always use external guides to prevent rod bending and side loads. The -S magnet supports CMSE/DMSE switches for position feedback.
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 JSIJ80X350-50S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it gives 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 300 to 350 mm. The nominal 350 mm is the maximum, and the retract end remains fixed.
