Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-10S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 275mm 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 JSIJ80X275-10S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend tuning to heavy automation. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the 25 mm rod, and the -S suffix means a built-in magnet is present for CMSE/DMSE position switches.
The -10 code defines a 10 mm external adjuster window, letting you shorten the extend stroke from the 275 mm maximum down to 265 mm without changing the hardware. This fine-tunes the end position perfectly for varying part sizes. Based on the 0.5 MPa rating, the cylinder handles about 1508 N of real work safely, translating to roughly 128 kg lifted vertically with a 2:1 margin. Remember that the air cushion only decelerates the stroke; use an external rod lock or pilot-operated check valve if you must hold a load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-10S Is Used
Press Fit Tuning
Adjusts the extend stroke within the 10 mm window to set precise insertion depths for varying bearing housings without swapping the cylinder.
Variable Length Diverter
Retimes the extend endpoint on the fly to deflect different package sizes on a packaging line while maintaining high push force.
Pallet Stop Calibration
Fine-tunes the stopping position of heavy pallets by shortening the stroke up to 10 mm, ensuring exact alignment for downstream robotics.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-10S the Right Cylinder?
When sizing this 80 mm bore, step down to a 63 mm unit if your force needs are under 1559 N at 0.5 MPa, or step up to a 100 mm bore if you need more than the 3927 N available here. The 10 mm adjustable window is ideal for sharing a spare cylinder across slightly different stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet allows CMSE/DMSE sensors to track position. Because the 275 mm stroke exceeds 300 mm when combined with the bore, ensure adequate external guiding to prevent side-load damage to the M22x1.5 rod thread.
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 JSIJ80X275-10S FAQ
This 80 mm bore cylinder uses a G3/8 port. 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 of 513 kgf at 1.0 MPa.
The -10 indicates a 10 mm external adjuster window. The nominal 275 mm extend stroke is the maximum, and you can shorten it on-site down to 265 mm to fine-tune the end position. The retract end remains fixed, and this mechanism does not lock the load.
