Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 900mm 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 JSIJ80X900-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore unit handles about 1508 N of real work, roughly 128 kg lifted vertically. The G3/8 ported body uses an extruded hard-anodized aluminium profile and is more compact than a same-bore ISO 15552 cylinder.
A 50 mm external adjuster lets you fine-tune the extend end position on site, making the usable forward travel 850 to 900 mm while the retract end stays fixed. This SKU lacks a magnet and cannot take a CMSE or DMSE sensor, so order an -S variant if you need position detection. The 29 mm adjustable air cushions only decelerate the piston near the ends and do not lock the load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50 Is Used
Transfer Line Diverter
Dial in the 850 to 900 mm extend reach with the 50 mm adjuster to push heavy pallets onto a side lane without overtravel.
Vertical Lift Gate
Lift roughly 128 kg of gate material using the 2513 N push force, tweaking the final raised position on site.
Long-Reach Push Station
Use the 80 mm bore thrust to clear large machined parts from a work area, relying on the 29 mm cushions to stop the 900 mm travel.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50 the Right Cylinder?
Size both ways against the 80 mm bore: the 63 mm gives 1559 N push at 0.5 MPa, while the 100 mm yields 3927 N. The 50 mm adjuster window is ideal for sharing one spare across stroke variants or dialing in final end positions without swapping the cylinder. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke is long, always use external guides to prevent rod bending and side loads. Without a magnet, this specific SKU cannot support 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 JSIJ80X900-50 FAQ
It has a G3/8 port and delivers 2513 N push and 2268 N pull at 0.5 MPa, or 3518 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 900 mm extend stroke is the maximum. An external stop screw lets you shorten the forward stroke by up to 50 mm on site, giving a usable extend range of 850 to 900 mm. The retract end remains fixed.
