Airtac JSI Series Standard Cylinder JSI100X550FA
The AirTAC Airtac JSI Series Standard Cylinder JSI100X550FA 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 JSI100X550FA
Delivering massive thrust in a tight footprint, this double-acting JIS-standard profile cylinder pushes with 3927 N and pulls with 3574 N at 0.5 MPa. The extruded hard-anodized aluminum barrel omits external rods entirely, making the unit shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. A heterogeneous two-way piston seal retains grease for long, low-friction life.
Because this SKU lacks the -S magnet, it cannot accept CMSE or DMSE position sensors. For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa (60% of the rated push), which safely lifts a 200 kg load vertically with a 2:1 margin. The G1/2 air port and M26x1.5 rod thread handle high flow rates required for moving the 32 mm rod at 30-800 mm/s.

Where the Airtac JSI Series Standard Cylinder JSI100X550FA Is Used
Injection Mold Clamping
Provides the 5497 N push force at 0.7 MPa needed to secure heavy injection mold halves, utilizing the FA flange to bolt directly to the press frame.
Pallet Diverting
Shifts loaded pallets along a high-throughput line, with the 550 mm stroke giving enough travel to clear wide product profiles completely.
Heavy Crate Pushing
Ejects dense freight crates from packaging stations, where the 200 kg vertical-lift equivalent translates into reliable horizontal mass movement.
Is the Airtac JSI Series Standard Cylinder JSI100X550FA the Right Cylinder?
If 3927 N of push at 0.5 MPa is too much, step down to the 80 mm bore (2513 N push); if you need more, the 125 mm bore offers 6136 N. This 550 mm stroke variant includes an FA flange mount for secure face-mounting, but because it lacks the -S suffix, you cannot fit reed or solid-state switches. The end-of-stroke air cushions decelerate the piston but do not function as a lock; if air is lost, the piston drifts. Use an external rod lock or pilot-operated check valve to hold a load. Furthermore, a 550 mm stroke generates significant leverage on the 32 mm rod, so external guide rails are recommended to prevent rod bending under side loads.
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 JSI100X550FA FAQ
At 0.5 MPa it pushes with 3927 N and pulls with 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port, an M26x1.5 rod thread, and has 33 mm adjustable air cushions at both ends.
It is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. It uses an extruded hard-anodized aluminum barrel with no external rods. Note that this specific SKU has no -S magnet, so it cannot accept CMSE or DMSE sensors.
