Airtac JSI Series Standard Cylinder JSI100X260S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X260S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 260mm 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 JSI100X260S
Generating 3927 N of push force at 0.5 MPa, this double-acting AirTAC profile cylinder saves valuable machine space by being noticeably shorter than an ISO 15552 unit of the same 100 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. Because the SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
Plan for about 2356 N of real work at 0.5 MPa, which safely lifts a 200 kg vertical load with a 2:1 margin. The G1/2 air port feeds the 32 mm hard-chrome rod, and adjustable 33 mm cushions at both ends decelerate the piston smoothly across its 30-800 mm/s speed range.

Where the Airtac JSI Series Standard Cylinder JSI100X260S Is Used
Injection Mold Clamping
Provides 3927 N of push at 0.5 MPa to secure mid-sized injection mold halves, utilizing the 260 mm stroke to accommodate varying die heights.
Heavy Pallet Diverting
Shifts loaded pallets along a packaging line, where the 200 kg vertical lift capacity and compact profile keep the diverting head within tight machine envelopes.
Vertical Carton Stacking
Lifts corrugated cartons to upper tiers, relying on the -S magnet and DMSE switches to confirm the 260 mm stroke position before releasing the load.
Is the Airtac JSI Series Standard Cylinder JSI100X260S the Right Cylinder?
If you need slightly less force, the 80 mm bore offers 2513 N push at 0.5 MPa, whereas stepping up to the 125 mm bore yields 6136 N for heavier demands. This 260 mm stroke sits comfortably below the 1500 mm standard limit, keeping rod bending stress minimal without requiring an external guide. Remember that the adjustable cushions only decelerate the piston near the end of travel; they do not function as a brake. If your application must hold a load vertically during air loss or valve centering, install an external rod lock or a pilot-operated check valve to prevent drift.
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 JSI100X260S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull; at 0.7 MPa it provides 5497 N push and 5003 N pull. The theoretical maximum force is 801 kgf at 1.0 MPa, and the air port size is G1/2.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving machine space. The -S suffix means it has a built-in magnet for CMSE or DMSE sensors in the side grooves.
