Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 25mm 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 JSIJ80X25-10
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS actuator brings heavy-duty clamping into a compact footprint that is noticeably shorter than a same-bore ISO 15552 cylinder. The extruded hard-anodized aluminium profile barrel keeps the assembly rigid without external rods. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
Fitted with a G3/8 port and an external stop screw, the -10 code provides a 10 mm on-site extend-shortening window. You can fine-tune the end position down to a 15 mm usable stroke without swapping the cylinder, while the retract end remains fixed. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10 Is Used
Short-Stroke Clamping
Provides 2513 N of solid clamping force at 0.5 MPa, with the 10 mm adjuster allowing precise tuning of the jaw closure without retooling the fixture.
Press Fit Positioning
Uses the external stop screw to set a 15 to 25 mm extend stroke for delicate press fits, ensuring components bottom out accurately every time.
Compact Ejector Station
Fits into tight machine spaces thanks to the shorter JIS profile barrel, delivering rapid ejection forces within a 25 mm travel window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X25-10 the Right Cylinder?
Size this 80 mm bore against the neighbouring 63 mm (2182 N push at 0.7 MPa) and 100 mm (5497 N push at 0.7 MPa) options to match your pressure limits. The 10 mm adjuster is perfect for sharing a single spare across slightly different short-stroke variants, letting you set the exact extend end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, you cannot add position sensors; choose the -S variant if you need CMSE or DMSE switches. Side loads should always be guided by external bearings to prevent rod 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 JSIJ80X25-10 FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N and pulls 3175 N, with a theoretical maximum force of 513 kgf at 1.0 MPa. It uses a G3/8 air port and features a 29 mm adjustable air cushion at each end.
The nominal 25 mm extend stroke is the maximum travel. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 15 to 25 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load.
