Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-20
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm 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 JSIJ80X800-20
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. The hard-anodized aluminum barrel keeps the overall body more compact than a same-bore ISO 15552 unit, while the G3/8 porting feeds the 25 mm rod for robust actuation.
The external adjuster allows you to trim the extend stroke by up to 20 mm directly on-site, giving a usable range of 780 to 800 mm without swapping the cylinder. It handles about 1508 N of real work safely, which means roughly 128 kg lifted vertically with a 2:1 margin. Note that this SKU lacks a magnet and cannot take CMSE/DMSE sensors; a plain cylinder also drifts on air loss, so fit an external rod lock for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-20 Is Used
Long-Transfer Diverter
Pushes heavy pallets along a 780 to 800 mm lane, using the 20 mm external adjuster to dial in the exact stopping distance without repositioning the cylinder body.
High-Bay Ejection Arm
Ejects packed goods from a vertical shelving system where the 2513 N push force clears the item and the compact JIS profile saves critical overhead clearance.
Press Sub-Assembly Stop
Acts as an adjustable hard stop for a sub-assembly press, fine-tuning the 20 mm extend window on-site to accommodate different material thicknesses.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-20 the Right Cylinder?
When sizing this unit, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927 N, letting you tune the force margin precisely. The 20 mm extend-shortening window is highly useful for synchronizing end positions across multiple stations or sharing a spare across stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is an 800 mm stroke, always use external guides to prevent rod bending and side-load damage. Select the -S variant if your application requires CMSE/DMSE magnetic sensing.
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 JSIJ80X800-20 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. It features an 80 mm bore, a 25 mm rod with an M22x1.5 thread, a G3/8 port, and 29 mm adjustable air cushions at both ends.
The external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable extend range of 780 to 800 mm. The nominal 800 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position but does not lock the load; you need a pilot-operated check valve or external rod lock to hold a load against air loss.
