Airtac JSI Series Standard Cylinder JSI100X400
The AirTAC Airtac JSI Series Standard Cylinder JSI100X400 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 400mm stroke, G1/2 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 JSI100X400
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X400 is a double-acting JIS-standard profile cylinder built for heavy-duty positioning. Its extruded hard-anodized aluminum barrel omits external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring low-friction operation over long cycle life.
With a 400 mm stroke, this model handles substantial linear motion while operating at speeds of 30-800 mm/s through its G1/2 air port. For practical sizing, plan for about 2356 N of real work at 0.5 MPa, which safely lifts roughly 200 kg vertically with a 2:1 margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position sensors.

Where the Airtac JSI Series Standard Cylinder JSI100X400 Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure heavy injection mold halves over the 400 mm opening stroke.
Pallet Diversion
Shifts loaded pallets laterally on a packaging line, utilizing the full 400 mm travel to clear adjacent lanes.
Vertical Lift Gate
Actuates a heavy materials handling gate, easily lifting roughly 200 kg of steel framework through its vertical cycle.
Is the Airtac JSI Series Standard Cylinder JSI100X400 the Right Cylinder?
When sizing this 100 mm bore, verify if the 80 mm class (delivering 2513 N push at 0.5 MPa) is sufficient, or if you need to step up to the 125 mm bore for 6136 N. For this 400 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. Note that a standard cylinder drifts when air is lost or the valve is centered; the adjustable 33 mm cushions only decelerate the piston near the end of travel. To hold a suspended load securely, install an external rod lock or a pilot-operated check valve.
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 JSI100X400 FAQ
The JSI100X400 delivers 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. It features a G1/2 air port, an M26x1.5 rod thread, and a 32 mm piston rod.
As a JIS-standard profile cylinder, the JSI100X400 features an extruded aluminum barrel without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. This space-saving footprint is ideal for tight machine layouts.
