The AirTAC Airtac JSI Series Standard Cylinder JSI80X30 is a genuine double acting JIS-standard air cylinder with a Ø80mm bore and 30mm 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, the AirTAC JSI80X30 is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the unit significantly shorter and more compact than a same-bore ISO 15552 cylinder without sacrificing structural rigidity.
Equipped with a G3/8 port and a 25 mm carbon steel rod, it handles speeds of 30-800 mm/s. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSE or DMSE position sensors. For real-world sizing, plan for about 1508 N of actual work at 0.5 MPa, which translates to lifting roughly 128 kg vertically with a 2:1 safety margin. The internal two-way piston seal retains grease to ensure long, low-friction service life.

Provides high clamping force in a short stroke for securing small injection mold inserts within confined machine frames.
Acts as a robust end-stop for heavy pallets on packaging lines, absorbing impact via its 29 mm adjustable air cushions.
Folds and holds heavy cardboard carton flaps during automated taping operations where a brief 30 mm travel is required.
If 2513 N of push at 0.5 MPa is excessive for your fixture, stepping down to the 63 mm bore yields 1559 N; conversely, upgrading to the 100 mm bore provides 3927 N for heavier payloads. This 80 mm bore uses an M22x1.5 rod thread and a 29 mm adjustable air cushion at both ends to soften end-of-stroke impact. Note that a standard cylinder drifts when air is lost or the valve is centered, as the cushion only decelerates the piston and acts as no lock. For suspended loads, integrate an external rod lock or a pilot-operated check valve. The short 30 mm stroke keeps the assembly highly rigid, minimizing rod-bending concerns.
Quick checklist
The JSI80X30 delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa. The air port size is G3/8.
No, because this SKU lacks the -S magnet suffix, it cannot accept CMSE or DMSE magnetic switches. You must select the JSI80X30-S variant to utilize the side sensor grooves for position detection.
