Airtac JSI Series Standard Cylinder JSI80X300
The AirTAC Airtac JSI Series Standard Cylinder JSI80X300 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.

About the Airtac JSI Series Standard Cylinder JSI80X300
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 ISO 15552 unit of the same 80 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this specific SKU lacks the -S magnet, it cannot host CMSE or DMSE position switches without changing the variant.
For practical sizing, plan for about 1508 N of real work at 0.5 MPa, which translates to lifting roughly 128 kg vertically with a 2:1 safety margin. Air enters via the G3/8 port, driving the 25 mm carbon steel rod at speeds between 30 and 800 mm/s. Adjustable 29 mm air cushions at both ends absorb end-of-stroke impact, though they only decelerate the piston and do not lock the load if air pressure drops.

Where the Airtac JSI Series Standard Cylinder JSI80X300 Is Used
Pallet Diversion
Pushes heavy wood or aluminum pallets sideways off a main conveyor line using its 2513 N push force and 300 mm travel.
Carton Stacking
Lifts packaged goods weighing up to 128 kg vertically onto outbound pallets, relying on the hard-anodized barrel for smooth operation.
Press Ejection
Ejects formed metal parts from a hydraulic press bed, utilizing the adjustable 29 mm cushions to soften the end-of-stroke impact.
Is the Airtac JSI Series Standard Cylinder JSI80X300 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm JSI yields 1559 N of push at 0.5 MPa, while moving up to a 100 mm bore provides 3927 N. Since this is a 300 mm stroke, external guides are strongly recommended to prevent rod bending and premature seal wear caused by side loads. Remember that a standard cylinder drifts when air is lost or the valve is centered; add an external rod lock or pilot-operated check valve if the load must be held in place. To add CMSE or DMSE sensors, you must select the -S magnet variant, as this base SKU cannot accept them.
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 JSI Series Standard Cylinder JSI80X300 FAQ
This 80 mm bore cylinder features a G3/8 air port and an M22x1.5 rod thread. It generates 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 JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore. It uses an extruded hard-anodized aluminum barrel with no external rods, saving space on tight machines.
