Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-100
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 350mm 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 JSIJ80X350-100
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 aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, dropping the usable forward travel from the 350 mm maximum down to 250 mm without swapping the cylinder. Air connects via a G3/8 port. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-100 Is Used
Press Tooling Stop
Dial in the exact 250 to 350 mm extend stop on-site to accommodate different material thicknesses without machining a new spacer block.
Multi-Length Divert
Adjust the extend window from 350 mm down to 250 mm on the fly to push varying box sizes onto different downstream lanes.
Pallet Positioning
Fine-tune the forward end position to align pallets precisely against a fixed stop, absorbing mechanical tolerance variations easily.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-100 the Right Cylinder?
Stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. The 80 mm bore hits a strong middle ground for medium-heavy tooling. The 100 mm adjuster window is ideal when you need to fine-tune the extend end position on-site or want a single spare cylinder that can cover multiple stroke variants between 250 and 350 mm. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 350 mm, always use an external guide rail to prevent rod bending and manage side loads. Without the -S suffix, this unit cannot support 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 JSIJ80X350-100 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 force is 513 kgf at 1.0 MPa. The air port size is G3/8.
The nominal 350 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 250 to 350 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
