Airtac JSI Series Standard Cylinder JSI100X150SFB
The AirTAC Airtac JSI Series Standard Cylinder JSI100X150SFB is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 150mm 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 JSI100X150SFB
Delivering 3927 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 100 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. A G1/2 port and M26x1.5 rod thread handle the required air volume and mounting loads.
Because the code includes the -S suffix, a built-in piston magnet is fitted so CMSE or DMSE switches can drop directly into the side grooves for position sensing. In real-world use, 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. The included FB front flange provides a robust mounting interface for this 150 mm stroke unit.

Where the Airtac JSI Series Standard Cylinder JSI100X150SFB Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure heavy injection mold halves, utilizing the FB flange for rigid face-mounting on the press frame.
Pallet Stopper Gate
Acts as a heavy-duty 150 mm stroke stop gate on high-throughput conveyor lines, using the built-in -S magnet to confirm gate closure for the packaging controller.
Press Ejection System
Ejects dense stamped metal parts from a hydraulic press, where the compact JIS profile saves critical clearance in a crowded tooling die.
Is the Airtac JSI Series Standard Cylinder JSI100X150SFB the Right Cylinder?
When sizing this 100 mm bore actuator, verify your force needs against its neighbors: a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 125 mm provides 6136 N. This model hits a solid middle ground for heavy payloads. The FB flange accessory supports straightforward face-mounting, and the -S magnet ensures compatibility with reed or electronic sensors. Operating speed ranges from 30-800 mm/s.
Remember that a standard pneumatic cylinder drifts if air pressure is lost or the valve is centered, as the adjustable 33 mm air cushions only decelerate the piston near stroke ends rather than locking it. To hold a vertical load securely in an emergency, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 JSI100X150SFB FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it provides 5497 N push and 5003 N pull. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving machine space. It uses an extruded aluminum barrel without external rods and includes an FB flange mount and -S magnet for CMSE/DMSE sensors.
