Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30 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 JSIJ80X500-30
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. It is noticeably shorter than an equivalent ISO 15552 model, utilizing an extruded hard-anodized aluminum barrel without external tie rods. The G3/8 porting feeds a double-acting single rod capable of 30-800 mm/s speeds.
The -30 code defines an external adjuster that lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 470-500 mm while the retract end stays fixed. This mechanism lets you fine-tune the end position without swapping the cylinder. In practice it handles about 1508 N of real work, which translates to lifting roughly 128 kg vertically with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30 Is Used
Press Stroke Tuning
Dial in the exact 470-500 mm end position on-site via the external adjuster to accommodate varying material thicknesses without changing the actuator.
Heavy Transfer Diverter
Pushes substantial pallets laterally using the 2513 N push force at 0.5 MPa, relying on the compact JIS profile to save machine footprint.
Vertical Lift Gate
Lifts roughly 128 kg vertically with a 2:1 safety margin, using the fixed retract end as a stable base while tuning the extend stop.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30 the Right Cylinder?
When sizing, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N, so the 80 mm sits squarely in the mid-heavy range. The adjustable stroke is ideal for sharing a spare across stroke variants or dialing in final end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 500 mm, you must support the load with external guides to prevent rod bending and side loads. As a non-magnetized SKU, it cannot accept position sensors.
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 JSIJ80X500-30 FAQ
This 80 mm bore cylinder uses a G3/8 port. It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
The nominal 500 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable range of 470-500 mm. The retract end is fixed. This stop only sets the end position; it does not lock the load.
