Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 80mm 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 JSIJ80X80-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder integrates a 75 mm external adjuster to shorten the extend stroke on site. The hard-anodized aluminium barrel omits external rods, making the body noticeably shorter and more compact 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 connections use a G3/8 port, and the unit runs at 30-800 mm/s.
The -75 code means the nominal 80 mm extend stroke can be reduced down to 5 mm without changing the cylinder itself, while the retract end remains fixed. This SKU has no magnet and cannot take a CMSE or DMSE sensor; order an -S variant if you need position detection. Note that the adjustable stop only sets the end position and decelerates the piston via the 29 mm air cushions—it is not a load lock, so fit an external rod lock or pilot-operated check valve if the load must be held on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-75 Is Used
Press Stroke Tuning
Dial in the exact 5 to 80 mm extend position on a light stamping press without swapping cylinders, using the external stop to accommodate varying material thicknesses.
Variable-Length Diverter
Adjust the extend reach on a package diverter arm on site to handle different box sizes, relying on the 2513 N push force to redirect heavy cartons reliably.
Shared Spare Cylinder
Keep one cylinder in maintenance stock for multiple machines with slightly different extend requirements, fine-tuning the end position during installation to minimize downtime.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-75 the Right Cylinder?
When sizing this 80 mm bore, step down to a 63 mm bore for 1559 N push at 0.5 MPa, or step up to a 100 mm bore for 3927 N if your payload exceeds the 1508 N safe working load. The 75 mm adjustable window is ideal for sharing a single spare cylinder across machines that need slightly different extend end-positions, letting you fine-tune the stroke on the floor. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot accept position sensors. For any stroke length at or above 300 mm, always guide the load externally to prevent side-load wear on the M22x1.5 rod thread and seals.
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 JSIJ80X80-75 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. The air port size is G3/8.
The nominal 80 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on site by up to 75 mm, giving a usable extend range of 5 to 80 mm. The retract end is fixed and cannot be adjusted.
