Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40 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 JSIJ80X500-40
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings heavy-duty actuation into a compact footprint that is noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum extruded barrel skips external rods for a clean exterior. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. Air connects via a G3/8 port, while a 25 mm rod and M22x1.5 thread manage the load.
The -40 code defines an external adjuster that lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 460 to 500 mm. Because the nominal 500 mm stroke is the maximum, you can fine-tune the end position without physically swapping the cylinder. Adjustable air cushions of 29 mm at each end absorb kinetic energy. This plain SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor; order an -S variant if you require position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40 Is Used
Press Stroke Trimming
Use the 40 mm extend-shortening window to precisely set the bottoming position of a pressing operation without changing the machine height.
Divertor End Tuning
Dial in the exact 460 to 500 mm reach of a diverter arm on-site to accommodate different package widths on the fly.
Long-Reach Transfer
Leverage the 2513 N push force to move heavy pallets over a 500 mm span, using external guides to manage the long rod.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-40 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while stepping up to a 100 mm bore raises it to 3927 N. The adjustable stroke feature is ideal for sharing a single spare across multiple stroke variants or dialing in final end positions on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a 500 mm stroke, you must support the load with external guides to prevent rod bending and excessive side loading. Remember that the air cushion only decelerates the piston; it does not hold the load. For vertical or suspended loads that must resist drift on air loss, add an external rod lock or a pilot-operated check valve.
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 JSIJ80X500-40 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod with an M22x1.5 thread, and 29 mm adjustable cushions at both ends.
The -40 designates an external adjuster that shortens the extend stroke by up to 40 mm on-site. The nominal 500 mm stroke remains the maximum, giving a usable extend range of 460 to 500 mm. The retract end is fixed, and the stop screw sets the end position rather than locking the load.
