Airtac JSI Series Standard Cylinder JSI100X500S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X500S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSI100X500S
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore double-acting actuator tackles heavy machinery tasks while maintaining a smaller footprint than an equivalent ISO 15552 cylinder. The hard-anodized aluminum extrusion omits external rods entirely, and the two-way NBR piston seal actively retains grease for low-friction longevity. Air enters via a G1/2 port to drive the 32 mm hard-chrome rod across a 500 mm travel distance.
Because the SKU includes the -S suffix, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise end-of-stroke detection. For real-world sizing, plan for roughly 2356 N of actual work at 0.5 MPa, which equates to lifting about 200 kg vertically with a 2:1 safety margin. Adjustable 33 mm air cushions at both ends absorb kinetic energy to protect the end caps.

Where the Airtac JSI Series Standard Cylinder JSI100X500S Is Used
Injection Mold Clamping
Provides the heavy 3927 N push force required to secure mid-sized injection mold halves, utilizing the 500 mm stroke to clear the tooling during part ejection.
Pallet Dispenser Pusher
Shoves empty pallets into positioning chutes using its 200 kg safe vertical-lift equivalent, relying on the compact profile to fit within tight conveyor framework.
Heavy Stamping Feed
Advances thick steel blanks into a hydraulic press, where the 33 mm adjustable air cushions absorb the kinetic energy of the heavy 100 mm piston at high cycle speeds.
Is the Airtac JSI Series Standard Cylinder JSI100X500S the Right Cylinder?
When sizing this 500 mm stroke unit against its neighbors, note the 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm option steps up to 6136 N. If your payload drops when air is lost or the valve centers, remember this cylinder will drift; the end cushions only decelerate the piston near stroke end and act purely as buffers, never as a locking brake. To hold a suspended load securely, install an external rod lock or a pilot-operated check valve.
Spanning half a meter of travel, the 32 mm rod is susceptible to bending under offset loads. Always use an external linear guide to prevent side-load damage and premature seal wear over such a long extension. The -S magnet matches perfectly with DMSE sensors for position feedback.
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 JSI100X500S FAQ
This 100 mm bore cylinder features 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.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore, saving valuable machine space. It achieves this via an extruded aluminum barrel with no external rods, while still offering LB, FA, FB, CA, CB, and TC mounting options.
