Airtac JSI Series Standard Cylinder JSI100X260
The AirTAC Airtac JSI Series Standard Cylinder JSI100X260 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 JSI100X260
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The extruded hard-anodized aluminum barrel features no external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches.
With a 260 mm stroke and a G1/2 air port, the unit is built for heavy-duty positioning. Plan for about 2356 N of real work at 0.5 MPa, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The adjustable 33 mm air cushions at both ends decelerate the 32 mm chrome rod smoothly, and you can mount it via LB foot, FA/FB flange, CA/CB/CR clevis, or TC trunnion.

Where the Airtac JSI Series Standard Cylinder JSI100X260 Is Used
Injection Mold Clamping
Provides the 3927 N push force needed to secure mid-sized injection mold halves during plastic part formation.
Press Ejection Systems
Uses its 260 mm stroke and 3574 N pull force at 0.5 MPa to eject formed metal sheets from compact mechanical presses.
Pallet Dispenser Pusher
Cycles heavy empty pallets into positioning stations, leveraging the 100 mm bore to move loads up to 200 kg vertically.
Is the Airtac JSI Series Standard Cylinder JSI100X260 the Right Cylinder?
If 3927 N of push at 0.5 MPa is too much, step down to the JSI80X80, which provides 2513 N. For even heavier machinery, the JSI125X250-S offers 6136 N. Note that this JSI100X260 variant has no magnet, so it cannot host magnetic sensors; choose a -S version if you need CMSE or DMSE switches. Also, a standard cylinder drifts when air is lost or the valve is centered—the cushion only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for held loads.
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 JSI100X260 FAQ
At 0.5 MPa it pushes with 3927 N and pulls with 3574 N. At 0.7 MPa the push is 5497 N and pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port 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. It uses an extruded aluminum barrel with no external rods, saving space on tight machines.
