Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-50 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 JSIJ80X500-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site flexibility to long-stroke automation. The hard-anodized aluminium barrel keeps the overall body more compact than a same-bore ISO 15552 unit. A G3/8 port supplies air, while adjustable cushions at both ends absorb the kinetic energy of the 500 mm travel.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable range of 450-500 mm without swapping the cylinder. This adjuster sets the end position; it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against air loss. 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 and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-50 Is Used
Long-Transfer Pushing
Advances pallets along a 500 mm conveyor section, using the 50 mm adjuster to dial in the exact push-off distance for different box sizes without changing the cylinder.
Multi-Height Pressing
Applies up to 3518 N of downward force at 0.7 MPa, with the external stop screw allowing quick on-site changes to the press depth for varying material thicknesses.
Diverting Gate Actuation
Drives a sorting diverter arm across a wide belt, relying on the compact JIS profile to fit within tight side-frame clearances where a longer ISO 15552 cylinder would clash.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-50 the Right Cylinder?
When sizing this unit, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter duties, while the 100 mm bore steps up to 3927 N if you need more thrust. The 50 mm adjuster window is ideal when you need to fine-tune a long end-position across multiple stations or share a spare cylinder across slightly different 450-500 mm stroke variants. Mounting options include FA, LB, TC, TCM1 and TCM2 brackets. Because the stroke is 500 mm, always use an external guide rail to prevent rod bending and side-load damage. As this is a non-magnet SKU, you cannot mount position sensors; select an -S variant if you need CMSE or DMSE switches.
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 JSIJ80X500-50 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa this rises to 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. The bore is 80 mm with a 25 mm rod, a G3/8 port, an M22x1.5 rod thread, and 29 mm adjustable cushions at both ends.
The nominal 500 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable extend range of 450-500 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
