Airtac JSI Series Standard Cylinder JSI100X25TC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X25TC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 25mm 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 JSI100X25TC
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X25TC is a JIS-standard double-acting profile cylinder built for tight machinery. Its extruded hard-anodized aluminum barrel omits external rods entirely, making it 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 service life.
This specific SKU lacks the -S magnet, meaning it cannot accept CMSE or DMSE position switches. 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. It features a G1/2 port and a 25 mm stroke, arriving configured for TC trunnion mounting.

Where the Airtac JSI Series Standard Cylinder JSI100X25TC Is Used
Injection Mold Clamping
Uses the 3927 N push force at 0.5 MPa to secure mid-sized injection mold halves within a compact machine frame where overall cylinder length is restricted.
Heavy Stamping Press
Provides a robust 25 mm high-force impact stroke for stamping sheet metal components, leveraging the hard-anodized barrel for wear resistance.
Pallet Stopper Gate
Acts as a heavy-duty physical stop block in high-mass pallet conveyors, safely halting loads using the TC trunnion mount to handle pivot stresses.
Is the Airtac JSI Series Standard Cylinder JSI100X25TC the Right Cylinder?
When sizing this 100 mm bore, stepping down to the 80 mm JSI yields 2513 N of push at 0.5 MPa, while the larger 125 mm bore provides 6136 N if your application demands more power. Because this is a plain double-acting cylinder, the piston will drift if air pressure drops or the valve is centered; the end-of-stroke air cushion only decelerates the piston rather than locking it. For suspended loads, install an external rod lock or pilot-operated check valve. The short 25 mm stroke keeps side-load stress minimal, but always verify your TC trunnion pin alignment to prevent rod binding.
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 JSI100X25TC FAQ
The 100 mm bore generates 3927 N push and 3574 N pull at 0.5 MPa, or 5497 N push and 5003 N pull at 0.7 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and M26x1.5 rod thread.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSE or DMSE switches. You must select the -S variant to use the side sensor grooves. The unit is configured for TC trunnion mounting and is shorter than a standard ISO 15552 cylinder.
