Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 500mm 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 JSIJ80X500-40S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. The hard-anodized aluminium barrel keeps the total length shorter than a comparable ISO 15552 unit. A built-in magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for precise end-of-stroke detection.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 460-500 mm while the retract end stays fixed. This on-site tuning handles about 1508 N of real work safely, roughly 128 kg lifted vertically. Air connects via a G3/8 port, and the 29 mm adjustable cushions decelerate the load. Note that the cushion only slows the piston; use an external rod lock or pilot-operated check valve to hold a load securely.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40S Is Used
Stamping Press Feed
Fine-tune the 460-500 mm extend position on-site to match varying material widths without swapping the entire cylinder.
Pallet Drop Station
Lower heavy fixtures using the 2513 N push force, relying on the 29 mm cushions to decelerate smoothly at the end of the 500 mm stroke.
Long-Reach Divert
Push products across a wide belt, using the built-in magnet and DMSE switches to confirm full extension.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40S the Right Cylinder?
Size this 80 mm bore against the 63 mm class, which provides 1559 N push at 0.5 MPa, or the 100 mm class offering 3927 N. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. Because this unit has the -S magnet, it accepts CMSE/DMSE sensors. Since the 500 mm stroke is quite long, always support the load with an external guide to prevent rod bending and side-load damage. The 40 mm adjuster window is ideal for sharing one spare cylinder across several stroke variants.
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 JSIJ80X500-40S 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 force is 513 kgf at 1.0 MPa.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 460-500 mm. The retract end remains fixed.
