Airtac JSI Series Standard Cylinder JSI100X230S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X230S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 230mm 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 JSI100X230S
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 unit of the same 100 mm bore. The extruded hard-anodized aluminum barrel eliminates external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. Because the SKU includes the -S suffix, a built-in piston magnet is present, allowing CMSE or DMSE electronic switches to drop directly into the side sensor grooves for position detection.
Air enters through the G1/2 port to drive the 32 mm carbon steel rod at speeds of 30-800 mm/s, with a 33 mm adjustable air cushion at both ends to decelerate the payload smoothly. For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin.

Where the Airtac JSI Series Standard Cylinder JSI100X230S Is Used
Injection Mold Clamping
Provides the 3927 N of push force at 0.5 MPa needed to secure medium-sized injection mold halves, utilizing the 230 mm stroke to clear the tooling during part ejection.
Heavy Pallet Diverter
Shifts loaded pallets weighing up to 200 kg on a packaging line, relying on the built-in -S magnet and DMSE sensors to confirm full diversion stroke.
Vertical Lift Gate
Raises a horizontal material handling gate through 230 mm of travel, with the adjustable 33 mm air cushions absorbing the kinetic energy at both stroke ends.
Is the Airtac JSI Series Standard Cylinder JSI100X230S the Right Cylinder?
When sizing this 100 mm bore against its neighbors, note the 80 mm class provides 2513 N of push at 0.5 MPa, while the 125 mm class jumps to 6136 N; this JSI100X230S sits comfortably in the middle for medium-heavy machinery. The 230 mm stroke is well within the 1500 mm maximum, but for any application exceeding 300 mm of travel, you should use external guide rails to prevent rod bending and premature seal wear under side loads. If the machine requires the load to remain suspended during a sudden air loss or valve centering, add an external pilot-operated check valve or a dedicated rod lock, as the standard air cushion only decelerates the piston near the end of stroke and will not hold a drifting load.
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 JSI100X230S FAQ
This 100 mm bore cylinder features a G1/2 air port and an M26x1.5 rod thread. It generates 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 force of 801 kgf at 1.0 MPa.
It is a JIS-standard profile cylinder that is physically shorter and more compact than an ISO 15552 cylinder of the same bore, saving space on tight machines. The extruded aluminum barrel has no external rods, and the -S suffix means it includes a magnet for side-groove CMSE/DMSE sensors.
