Airtac JSI Series Standard Cylinder JSI100X800STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X800STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 800mm 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 JSI100X800STC
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. Air connects via a G1/2 port, driving the 32 mm carbon steel rod at speeds of 30-800 mm/s.
Because the model code includes an S, a built-in piston magnet is fitted, allowing CMSE or DMSE switches to drop directly into the side sensor grooves for position detection. In real-world use, plan for about 2356 N of actual work at 0.5 MPa, which means it can lift roughly 200 kg vertically with a 2:1 safety margin. The 33 mm adjustable air cushions at both ends absorb kinetic energy smoothly at stroke ends.

Where the Airtac JSI Series Standard Cylinder JSI100X800STC Is Used
Pallet Transfer Line
Indexes heavy timber pallets along a 800 mm stroke using 3927 N of push force, relying on the TC trunnion to accommodate slight angular misalignment during transit.
Vertical Material Lift
Hoists 200 kg component racks between machinery levels, utilizing the built-in -S magnet to trigger DMSE descent sensors at the precise lower stopping point.
Press Ejection System
Clears stamped metal parts from a 100-ton press bed, absorbing rapid deceleration through the 33 mm adjustable air cushions to protect the tooling.
Is the Airtac JSI Series Standard Cylinder JSI100X800STC the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI63 provides 1559 N of push at 0.5 MPa, while moving up to a JSI125 yields 6136 N. This JSI100X800STC variant features a TC trunnion mount, ideal for pivoting loads, and includes the S magnet for electronic or reed sensing. Keep in mind the standard JSI does not hold its position if air pressure drops or the valve centers—the piston will drift, and the cushions only decelerate near the end of travel, so add an external rod lock or pilot-operated check valve if you need to secure a suspended load.
At an 800 mm stroke, the 32 mm rod is susceptible to bending under lateral stress. Always use external guide rails to support the load and prevent side-loading, ensuring the cylinder only provides linear push and pull forces rather than acting as a structural bearing.
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 JSI100X800STC FAQ
The 100 mm bore uses a G1/2 air port and an M26x1.5 rod thread. It generates 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
This cylinder is built to JIS standards using an extruded aluminum profile without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same bore. It is not dimensionally interchangeable with ISO 15552 but offers superior space efficiency on tight machinery.
