Airtac JSI Series Standard Cylinder JSI100X1200
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1200 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 JSI100X1200
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 ISO 15552 cylinder 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. Operating at speeds of 30-800 mm/s, it features a G1/2 air port and an M26x1.5 rod-end thread.
For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa, which safely lifts a 200 kg load vertically with a 2:1 margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. The 33 mm adjustable air cushions at both ends absorb end-of-stroke impact, and related types like the JSID double-rod or JSIJ adjustable-stroke variants cover specialized motion needs.

Where the Airtac JSI Series Standard Cylinder JSI100X1200 Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between machining centers over a 1200 mm gap using its 3927 N push force at 0.5 MPa.
Automated Storage Crane
Drives the horizontal extractor arm in high-bay racking, where the compact JIS profile saves overhead clearance.
Injection Mold Ejector
Actuates a large secondary ejection mechanism for automotive trim parts, relying on the 33 mm cushions to halt smoothly.
Is the Airtac JSI Series Standard Cylinder JSI100X1200 the Right Cylinder?
When sizing this 100 mm bore unit, the neighboring JSI80 offers 2513 N push at 0.5 MPa for lighter loads, while the larger JSI125 steps up to 6136 N if your application demands more power. Since this 1200 mm stroke is highly extended, you must use an external guide to prevent rod bending and manage side loads. Note that a standard cylinder drifts when air is lost or the valve is centered; the cushion only decelerates the piston near stroke end and acts as no lock. For secure load holding, 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 JSI100X1200 FAQ
This 100 mm bore cylinder 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.
No, this specific SKU does not include a magnet, so it cannot accept CMSE or DMSE switches. You must select the -S variant to enable side-groove sensor mounting.
