Airtac JSI Series Standard Cylinder JSI100X600SFA
The AirTAC Airtac JSI Series Standard Cylinder JSI100X600SFA is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 600mm 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 JSI100X600SFA
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 denotes a built-in magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position detection.
For real-world sizing, plan for around 2356 N of actual work at 0.5 MPa (about 60 percent of the rated push), which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The unit features a 32 mm carbon steel rod with an M26x1.5 thread, G1/2 air ports, and 33 mm adjustable air cushions at both ends to decelerate the piston smoothly over the 600 mm travel.

Where the Airtac JSI Series Standard Cylinder JSI100X600SFA Is Used
Pallet Transfer Diversion
Pushes heavy loaded pallets onto a secondary packaging line using its 3927 N push force at 0.5 MPa, with the FA flange handling the heavy lateral mounting stresses.
Vertical Lift Gate
Raises a 200 kg material handling gate over the 600 mm stroke, relying on the built-in -S magnet and DMSE sensors to confirm the fully open position.
Injection Mold Ejection
Ejects large molded plastic automotive panels from a press, utilizing the 33 mm adjustable air cushions to soften the full extension impact at high cycling speeds.
Is the Airtac JSI Series Standard Cylinder JSI100X600SFA the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI63 yields 1559 N of push at 0.5 MPa, while stepping up to the JSI125 provides 6136 N. The included FA flange accessory provides a robust front mounting interface for this long 600 mm stroke. Because standard double-acting cylinders drift when air is lost or a valve centers, you must add an external rod lock or pilot-operated check valve if the application requires holding a suspended load. The end-of-stroke cushions only decelerate travel and cannot act as a brake.
At a 600 mm stroke, the 32 mm rod is subjected to higher bending moments under side loads. To prevent premature seal wear and rod damage, guide the load externally and ensure the piston rod strictly operates in tension or compression without lateral force. The cylinder operates at 30-800 mm/s and accepts a maximum standard stroke of 1500 mm.
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 JSI100X600SFA FAQ
This 100 mm bore cylinder features a G1/2 air port and an M26x1.5 rod thread. The thrust output is 3927 N push and 3574 N pull at 0.5 MPa, increasing to 5497 N push and 5003 N pull at 0.7 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
The JSI series is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving space without losing force. The hard-anodized aluminum barrel has no external rods, and the included FA flange allows rigid front mounting for demanding applications.
