Airtac JSI Series Standard Cylinder JSI100X190S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X190S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 190mm 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 JSI100X190S
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 ISO 15552 cylinder of the same 100 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 the -S suffix provides a built-in piston magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa, which safely lifts a 200 kg vertical load with a 2:1 margin. The unit features a 32 mm carbon steel rod with an M26x1.5 thread, adjustable 33 mm air cushions at both ends, and a G1/2 port. It operates between 0.15-1.0 MPa at speeds of 30-800 mm/s.

Where the Airtac JSI Series Standard Cylinder JSI100X190S Is Used
Injection Mold Clamping
Provides the heavy 3927 N push force required to secure injection mold halves within compact machinery frames.
Pallet Stopper Gate
Acts as a robust 190 mm stroke stopper gate on high-throughput conveyor lines, handling heavy pallets with ease.
Press Ejection System
Ejects dense formed metal parts from hydraulic presses, using the 33 mm cushions to absorb end-of-stroke impact.
Is the Airtac JSI Series Standard Cylinder JSI100X190S the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI63 gives 1559 N push at 0.5 MPa, while stepping up to a JSI125 yields 6136 N. This JSI100X190S includes the -S magnet for CMSE/DMSE sensors and supports LB foot, FA/FB flange, CA/CB/CR clevis, TC trunnion mounts, or an I/Y/F/U rod knuckle. Keep in mind the adjustable air cushion only decelerates the piston near stroke end; if air is lost, the piston drifts. To hold a 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 JSI100X190S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it gives 5497 N push and 5003 N pull. The theoretical maximum is 801 kgf at 1.0 MPa. The air port is G1/2, and the rod thread is M26x1.5.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 unit of the same bore. The -S suffix means it has a built-in magnet, allowing CMSE or DMSE switches to drop into the side grooves for position detection.
