Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-100
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-100 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 JSIJ80X800-100
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder handles about 1508 N of real work, roughly 128 kg lifted vertically. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit, while the G3/8 port feeds a 25 mm rod running at 30-800 mm/s.
The external adjuster lets you shorten the extend stroke on site by up to 100 mm, giving a usable 700-800 mm range without changing the cylinder itself. It is a double-acting single-rod actuator with 29 mm adjustable air cushions at both ends. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors, and the cushions only decelerate the load rather than holding it on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-100 Is Used
Long-Transfer Diversion
Pushes heavy pallets along a 700-800 mm transfer line, using the adjuster to dial the exact push distance without swapping actuators.
High-Bay Ejection
Ejects goods from a vertical rack where the 100 mm window sets the precise clearance, relying on 2513 N of push at 0.5 MPa.
Large-Part Pressing
Presses components over an 800 mm travel, fine-tuning the final 100 mm of the stroke on site to accommodate material thickness variations.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-100 the Right Cylinder?
Size this 80 mm bore against the neighbouring 63 mm (1559 N push at 0.5 MPa) and 100 mm (3927 N push) options to match your force needs. The 100 mm extend-shortening window is ideal when you need to fine-tune a long end position on site or want a shared spare across stroke variants. Mounting options include FA, LB, TC, TCM1 and TCM2. Because the stroke is 800 mm, always use an external guide to prevent rod bending and side loads. Add the -S variant if you require CMSE/DMSE sensors, as this plain SKU cannot accept them.
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 JSIJ80X800-100 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N; at 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod with an M22x1.5 thread, and 29 mm adjustable cushions.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, yielding a 700-800 mm usable range, while the retract end remains fixed. This mechanism sets the end position and is not a load lock.
