The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 400mm 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.
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty adjustment. Its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds a 30-800 mm/s speed range, while the M22x1.5 rod thread and 29 mm cushions handle solid end-of-travel deceleration.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 360-400 mm without swapping the cylinder. It handles about 1508 N of real work safely, which means lifting roughly 128 kg vertically. Because this is an -S SKU, a built-in magnet allows CMSE or DMSE sensors to drop directly into the side grooves for position detection.

| Max (@1.0 MPa) | 513 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Dial in the exact 360-400 mm extend position on a light assembly press without machining new hard stops.
Fine-tune the extend reach of a heavy diverter arm on-site to accommodate varying package widths.
Set the precise end position for a pallet stop gate and lock it in with the external adjuster.
When sizing this unit, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter jobs, while the 100 mm bore steps up to 3927 N if you need more power. The 40 mm adjuster is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Since the stroke is 400 mm, always use external guides to prevent rod bending and manage side loads. The retract end remains fixed during adjustment.
Quick checklist
It pushes 2513 N and pulls 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 400 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 360-400 mm. The retract end is fixed, and the adjuster only sets the end position; it does not lock the load.
