Airtac JSI Series Standard Cylinder JSI100X550
The AirTAC Airtac JSI Series Standard Cylinder JSI100X550 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 550mm 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 JSI100X550
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X550 is a double-acting JIS-standard profile cylinder built for heavy-duty automation. Its extruded hard-anodized aluminum barrel omits external rods, making the unit noticeably shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring long, low-friction life even under demanding cycles.
With a 550 mm stroke and a robust 32 mm piston rod, this model operates at 30-800 mm/s via a G1/2 port. Plan for about 2356 N of real work at 0.5 MPa, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. Note that this SKU lacks the -S magnet, so it cannot host CMSE or DMSE position sensors.

Where the Airtac JSI Series Standard Cylinder JSI100X550 Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure heavy injection mold halves during the 550 mm closing cycle.
Pallet Diversion
Shifts loaded pallets along a transfer line, using the long 550 mm stroke to move parts cleanly between adjacent belts.
Vertical Lift Gate
Actuates a heavy materials handling gate, safely lifting components while relying on external guides for stability.
Is the Airtac JSI Series Standard Cylinder JSI100X550 the Right Cylinder?
When sizing this 100 mm bore actuator, consider the 80 mm option (2513 N push at 0.5 MPa) for lighter loads, or the 125 mm bore (6136 N) if you need substantially more thrust. Because this is a 550 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. Remember that the adjustable air cushion only decelerates the piston near stroke end; it will not hold a load if air pressure drops. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve to prevent drifting.
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 JSI100X550 FAQ
This 100 mm bore cylinder features a G1/2 port and delivers 3927 N push / 3574 N pull at 0.5 MPa, 5497 N push / 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 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 bore. This space-saving extruded barrel design omits external rods while retaining adjustable cushions at both ends.
