Airtac JSI Series Standard Cylinder JSI100X1200STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1200STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1200mm 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 JSI100X1200STC
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore cylinder handles heavy-duty automation with ease. The JSI100X1200STC features a JIS-standard extruded aluminum profile that is noticeably shorter and more compact than an equivalent ISO 15552 cylinder, saving valuable machine space. Its hard-anodized barrel lacks external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Equipped with a G1/2 port and an internal magnet, it supports CMSE and DMSE sensors that drop directly into the side grooves for precise end-of-stroke detection.
For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa, which safely lifts roughly 200 kg vertically with a 2:1 margin. The 1200 mm stroke falls within the 1500 mm standard maximum, operating at speeds of 30-800 mm/s. Adjustable air cushions at both ends decelerate the heavy payload smoothly, and the included TC trunnion mount provides a pivoting anchor point for articulated mechanisms.

Where the Airtac JSI Series Standard Cylinder JSI100X1200STC Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between machining centers, utilizing the 3927 N push force to overcome sliding friction over the 1200 mm travel distance.
High-Bay Storage Extraction
Extracts deep-set totes from automated storage racks, where the compact JIS profile saves critical space and the TC trunnion accommodates structural pivot angles.
Large Press Feeding
Feeds heavy steel blanks into a hydraulic press, relying on the adjustable cushions to smoothly decelerate the 200 kg equivalent load at stroke end.
Is the Airtac JSI Series Standard Cylinder JSI100X1200STC the Right Cylinder?
When sizing this 100 mm bore actuator, stepping down to a JSI80X125 yields 2513 N of push force at 0.5 MPa, whereas stepping up to a JSI125X125STC provides 6136 N. Choose this model when your application requires the 3927 N output and a long 1200 mm reach. Because this is a plain double-acting cylinder, it will not hold a suspended load if air pressure drops or the valve is centered; the piston will drift. To prevent vertical dropping, integrate an external rod lock or a pilot-operated check valve. Additionally, at 1200 mm of extension, the 32 mm rod is highly susceptible to side-loading and bending; always use external linear guides to support the load and prevent premature seal failure. The built-in magnet allows seamless integration with CMSE or DMSE reed and electronic switches.

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 JSI100X1200STC FAQ
This 100 mm bore model uses a G1/2 port. At 0.5 MPa it provides 3927 N of push force and 3574 N of pull force. At 0.7 MPa, push is 5497 N and pull is 5003 N. The theoretical maximum force is 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 bore. This specific SKU includes a TC trunnion mount for pivoting applications and features a built-in magnet for CMSE/DMSE sensors.
