Airtac JSI Series Standard Cylinder JSI100X475S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X475S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 475mm 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 JSI100X475S
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore cylinder handles heavy-duty automation with ease. Built to JIS standards, its extruded hard-anodized aluminum profile is purposefully shorter and more compact than an equivalent ISO 15552 cylinder of the same bore, saving valuable machine space without sacrificing power. The two-way piston seal retains grease for a long, low-friction service life.
Because this SKU includes the -S magnet, it is fully ready for CMSE or DMSE position switches that drop directly into the side sensor grooves. For practical sizing, plan for about 2356 N of real work at 0.5 MPa, which means it safely lifts roughly 200 kg vertically with a 2:1 margin. The unit features a G1/2 port, an M26x1.5 rod thread, and 33 mm adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSI Series Standard Cylinder JSI100X475S Is Used
Automotive Body Welding
Clamps heavy chassis panels with 3927 N of force at 0.5 MPa, while the 475 mm stroke reaches across wide welding fixtures.
Pallet Transfer Divert
Pushes loaded pallets onto secondary lines, using the built-in -S magnet to confirm full extension via CMSE sensors.
Heavy Crate Ejection
Ejects dense finished goods from packaging stations, relying on the 33 mm adjustable cushions to brake the 475 mm travel smoothly.
Is the Airtac JSI Series Standard Cylinder JSI100X475S the Right Cylinder?
When sizing this 100 mm bore model, the smaller JSI80 offers 2513 N push at 0.5 MPa, while stepping up to the JSI125 yields 6136 N, giving you clear force boundaries if your load changes. With a 475 mm stroke, the 32 mm rod is highly susceptible to side-loading and bending; always use external guide rails to support the payload and prevent premature seal wear.
This JSI100X475S variant includes the -S magnet for direct CMSE/DMSE sensor integration. Remember that a standard cylinder will drift and cannot hold a load if air pressure drops or the valve is centered—the end cushions only decelerate the piston, so add an external rod lock or pilot-operated check valve if you need strict position holding.
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 JSI100X475S FAQ
This 100 mm bore cylinder has a G1/2 port and generates 3927 N push / 3574 N pull at 0.5 MPa, 5497 N push / 5003 N pull at 0.7 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, utilizing an extruded aluminum barrel without external rods to save machine footprint.
