Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30S 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 JSIJ80X500-30S
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 extrusion makes it 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 allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable range of 470 to 500 mm without changing the cylinder itself. Because this is an -S SKU, it includes a piston magnet for CMSE/DMSE sensors in the side grooves. The G3/8 port feeds the 29 mm adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30S Is Used
Pallet Divert Stroke Tuning
Dial in the exact 470 to 500 mm extend reach to push pallets off a line without relocating the cylinder mounts.
Press Head Positioning
Fine-tune the downward extend end position by up to 30 mm on-site to accommodate different material thicknesses.
Shared Spare Inventory
Keep one adjustable cylinder in stock and shorten the extend stroke on the floor to cover several 80 mm bore machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-30S the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N, so the 80 mm sits squarely in the mid-heavy range. The adjustable -30 mm window is ideal for fine-tuning the extend end position on-site or standardizing one spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 500 mm, you must use external guides to prevent rod bending and manage side loads. A plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve for held loads.
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 JSIJ80X500-30S 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. This 80 mm bore unit uses a G3/8 port and features a 25 mm rod with an M22x1.5 thread.
The nominal 500 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 470 to 500 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
