Airtac JSI Series Standard Cylinder JSI100X1000STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1000STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1000mm 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 JSI100X1000STC
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 equivalent ISO 15552 unit 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. A built-in magnet (-S) allows CMSE or DMSE electronic switches to drop directly into the side grooves for position sensing.
Plan for roughly 2356 N of real work at 0.5 MPa, which safely lifts about 200 kg vertically with a 2:1 margin. The unit features a G1/2 air port, an M26x1.5 rod-end thread, and 33 mm adjustable air cushions at both ends to decelerate the payload smoothly. For tasks needing opposing or adjustable movements, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Where the Airtac JSI Series Standard Cylinder JSI100X1000STC Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between machining centers, utilizing the 3927 N push force to overcome sliding friction over the full 1000 mm travel.
Automated Storage Crane
Drives the horizontal extraction arm in a high-density vertical lift module, where the compact JIS profile saves critical overhead clearance.
Large Carton Erector
Actuates the folding mechanism for oversized corrugated boxes, relying on the 33 mm air cushions to soften the impact at full extension.
Is the Airtac JSI Series Standard Cylinder JSI100X1000STC the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI80 drops the 0.5 MPa push force to 2513 N, while moving up to a JSI125 raises it to 6136 N. The included TC trunnion mount provides a pivoting axis that accommodates slight misalignments over long distances. Because this model features a 1000 mm stroke, external guide rails are strongly recommended to prevent rod bending and excessive side-loading on the front cover packing.
Remember that a standard pneumatic cylinder drifts when air is lost or the valve is centered; the adjustable cushion only decelerates the piston near stroke end and does not act as a lock. To suspend a load safely in an emergency, install an external rod lock or a pilot-operated check valve.
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 JSI100X1000STC FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3574 N of pull force. At 0.7 MPa, push increases to 5497 N and pull to 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
No, a standard pneumatic cylinder will drift downward if air is lost or the directional valve is centered. The adjustable air cushions only decelerate the piston near the end of the stroke and do not function as a braking lock. You must add an external rod lock or pilot-operated check valve to hold a vertical load securely.
