Airtac JSI Series Standard Cylinder JSI100X75S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X75S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 75mm 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 JSI100X75S
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore cylinder is built for heavy machinery. As a JIS-standard profile unit, it is notably shorter and more compact than an equivalent ISO 15552 model, saving valuable space on dense production lines. 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.
Equipped with a piston magnet (-S), it accepts CMSE or DMSE reed and electronic sensors that drop directly into the side grooves for position detection. Plan for about 2356 N of real work at 0.5 MPa, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The unit features a G1/2 port, an M26x1.5 rod thread, and adjustable 33 mm air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSI Series Standard Cylinder JSI100X75S Is Used
Injection Mold Clamping
Provides the robust 3927 N push force needed to secure mid-sized injection mold halves, utilizing the compact JIS profile to fit within tight press enclosures.
Palletized Goods Diversion
Actuates heavy diverter arms on packaging conveyors, easily handling the 200 kg vertical lift equivalent to redirect loaded pallets onto secondary lines.
Press Ejection Systems
Drives ejection pins in automated stamping presses, relying on the 33 mm adjustable air cushions to softly stop the 32 mm rod at stroke end.
Is the Airtac JSI Series Standard Cylinder JSI100X75S the Right Cylinder?
When sizing this 100 mm bore actuator, compare its 3927 N push force at 0.5 MPa against the neighboring options: stepping down to an 80 mm bore yields 2513 N, while stepping up to a 125 mm bore provides 6136 N. Because this is a standard 75 mm stroke under the 1500 mm maximum, no side-load concerns arise, but always ensure the mounting method—whether LB foot, FA/FB flange, TC trunnion, or an I/Y/F/U rod knuckle—matches your frame geometry.
Remember that the adjustable air cushion only decelerates the piston near the stroke ends and does not function as a braking device. If your application must hold a vertical load when air pressure drops or the valve is centered, you must add an external rod lock or a pilot-operated check valve to prevent drifting.
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 JSI100X75S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3574 N. At 0.7 MPa, push is 5497 N and pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore cylinder uses a G1/2 air port, a 32 mm rod, and features an M26x1.5 rod-end thread.
No, the -S designation means it has a piston magnet for CMSE or DMSE position sensors, but it does not lock the rod. If air is lost or the valve is centered, the piston will drift. You need an external rod lock or pilot-operated check valve to hold a load safely.
