The AirTAC Airtac JSI Series Standard Cylinder JSI80X300FA is a genuine double acting JIS-standard air cylinder with a Ø80mm bore and 300mm 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 double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an equivalent ISO 15552 unit of the same 80 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for a long, low-friction service life. It features a 25 mm piston rod, M22x1.5 rod-end thread, and G3/8 air ports.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches without changing to a magnetized variant. In practical terms, you can plan for roughly 1508 N of real work at 0.5 MPa, which translates to lifting about 128 kg vertically with a 2:1 safety margin.

Pushes heavy wooden pallets sideways onto a secondary packaging line using its 2513 N push force at 0.5 MPa.
Clears stamped metal parts from a hydraulic press bed over a 300 mm reach, requiring the FA flange to handle the shock.
Raises a 120 kg material handling gate vertically, safely within the 128 kg computed lift capacity at 0.5 MPa.
When sizing this 80 mm bore, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while moving up to a 100 mm bore increases it to 3927 N. The included FA flange accessory provides a solid front mounting interface for straightforward bolt-on installation. Since this is a 300 mm stroke, external guides are highly recommended to prevent rod bending and absorb side loads during long extensions.
Note that a standard air cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. The adjustable 29 mm air cushions at both ends only serve to decelerate the piston near the stroke ends, so fit an external rod lock or pilot-operated check valve if you need to secure a suspended load.
Quick checklist
This 80 mm bore cylinder uses a G3/8 air port and an M22x1.5 rod thread. The thrust output is 2513 N push and 2268 N pull at 0.5 MPa, increasing to 3518 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force at 1.0 MPa is 513 kgf.
No, this specific SKU does not include the -S magnet option, meaning CMSE or DMSE switches cannot detect the piston. You must select an -S variant of the JSI80 to enable magnetic sensing capabilities.
