Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 100mm 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 JSIJ80X100-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to heavy pneumatic machinery. Its external stop screw provides a 75 mm adjustment window, meaning you can shorten the extend stroke from the 100 mm maximum down to 25 mm without swapping the unit. The retract end remains fixed. Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. It handles about 1508 N of real work, roughly 128 kg lifted vertically with a 2:1 margin.
This double-acting single-rod actuator uses a G3/8 port and a 25 mm piston rod with an M22x1.5 thread. Adjustable 29 mm air cushions at both ends absorb kinetic energy near the end of travel. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; you would need the -S variant for position detection. Furthermore, the cushion decelerates the load but does not hold it on air loss—for any suspended load, fit an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-75 Is Used
Press Stroke Tuning
Dial in the exact 25 to 100 mm clamping extension on a light press without machining custom spacers or changing the cylinder.
Variable Transfer Stops
Adjust the extend stop position on the fly for diverter arms handling mixed product sizes on a single packaging line.
Shared Spare Actuator
Keep one cylinder in stock and set the 75 mm window to match various 80 mm bore machines, minimizing inventory complexity.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-75 the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate both directions: the smaller 63 mm bore yields 1559 N push at 0.5 MPa, while the larger 100 mm bore jumps to 3927 N. The 75 mm adjustable window is exceptionally useful when you want a shared spare across machines with slightly different extend lengths, or when you need to fine-tune the end position on-site without disassembling the cylinder. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this model has no -S suffix, it cannot host magnetic sensors. For any stroke at or above 300 mm, always use a external guide rail to prevent side-load damage to the rod seal.
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 JSIJ80X100-75 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it delivers 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 100 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable extend range of 25 to 100 mm. The retract end is fixed, and the stop sets the end position rather than locking the load.
