Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-30
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-30 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 JSIJ80X100-30
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 automation. The external stop screw lets you shorten the forward travel by up to 30 mm, yielding a usable 70 to 100 mm range while the retract end remains fixed. You can fine-tune the end position without physically swapping the cylinder. Built with an extruded hard-anodized aluminum barrel, the body is 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. The unit features a 25 mm rod, an M22x1.5 rod thread, and G3/8 ports.
This double-acting, single-rod actuator relies on adjustable 29 mm air cushions at both ends to decelerate the payload smoothly. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Note that the cushion only slows the piston near the end of travel; a plain cylinder does not hold load on air loss. To prevent drift, you must fit an external rod lock or a pilot-operated check valve.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 70 to 100 mm extend position for seating bearings without changing the actuator body.
Variable Length Stops
Provides an adjustable hard stop for diverter arms on packaging lines where product lengths frequently change.
Pallet Positioning
Offers a robust 2513 N push force to square heavy pallets, with a 30 mm window to compensate for fixture wear.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-30 the Right Cylinder?
When sizing this 80 mm bore, compare it against the neighboring 63 mm and 100 mm options. The 63 mm bore yields 1559 N push at 0.5 MPa, whereas the 100 mm bore jumps to 3927 N, so choose the 80 mm for loads around 1508 N. The adjustable-stroke mechanism is ideal when you need to share a single spare cylinder across several stroke variants or fine-tune the end position on-site. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. For any stroke length of 300 mm or more, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ80X100-30 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. This 80 mm bore cylinder uses a G3/8 air port.
The nominal 100 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable forward range of 70 to 100 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
