Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-10
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 250mm 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 JSIJ80X250-10
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings compact power to pneumatic setups. The extruded hard-anodized aluminium barrel leaves external tie-rods behind, making the overall body shorter than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin. Air connects via a G3/8 port, driving a 25 mm piston rod at 30-800 mm/s.
The -10 suffix marks an external adjuster that shortens the extend stroke by up to 10 mm on site, giving a usable range of 240-250 mm without swapping the cylinder. This on-site end-position tuning is ideal for sharing spares across stroke variants. Note that this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors. The retract end remains fixed, and while adjustable 29 mm air cushions decelerate the piston at both ends, a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-10 Is Used
Press Fit Tuning
Dial in the exact 240-250 mm extend endpoint on-site via the 10 mm adjuster window to perfect light-duty press fits without reprogramming machine stops.
Divert Arm Positioning
Leverage the 2513 N push force to actuate heavy conveyor divert arms, using the compact JIS profile to save axial space in tight transfer lines.
Pallet Stop Adjustment
Fine-tune the retract-to-extend stop position for varying pallet sizes, relying on the 29 mm adjustable cushions to decelerate the load smoothly.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-10 the Right Cylinder?
When sizing this 80 mm bore, the neighbouring 63 mm option yields 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927 N, letting you fine-tune force margins. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. Because this is a no-magnet SKU, position sensing is unavailable here; choose an -S variant if you need CMSE or DMSE switches. For this 250 mm stroke, always guide the load to prevent rod side-loading, and remember the 10 mm adjuster lets you dial in the exact extend endpoint mechanically. The G3/8 port and M22x1.5 rod thread match the standard 80 mm JIS architecture.
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 JSIJ80X250-10 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it yields 3518 N push and 3175 N pull. The theoretical max force is 513 kgf at 1.0 MPa. It features an 80 mm bore, a 25 mm rod with an M22x1.5 thread, a G3/8 port, and 29 mm adjustable cushions at both ends.
The nominal 250 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable extend range of 240-250 mm for fine-tuning the end position. The retract end is fixed, and this stop mechanism is for positioning only, not for holding a load on air loss.
