Airtac JSI Series Standard Cylinder JSI100X380S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X380S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 380mm 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 JSI100X380S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X380S is a JIS-standard profile cylinder built for heavy-duty automation. Its extruded hard-anodized aluminum barrel omits external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring low-friction operation over long cycle counts. Fitted with a G1/2 port and an M26x1.5 rod thread, it handles speeds of 30-800 mm/s.
Because this SKU includes the -S magnet, CMSE or DMSE switches drop directly into the side sensor grooves for precise position detection. Plan for roughly 2356 N of real work at 0.5 MPa, which translates to lifting about 200 kg vertically with a 2:1 safety margin. The 33 mm adjustable air cushions at both ends absorb kinetic energy smoothly, though they only decelerate the piston near stroke end rather than locking it in place.

Where the Airtac JSI Series Standard Cylinder JSI100X380S Is Used
Automotive Body Welding
Clamps heavy steel chassis panels securely in robotic welding cells, utilizing the 3927 N push force to hold parts against fixture pins.
Pallet Diverting
Pushes fully loaded 150 kg pallets sideways onto spur lines, safely within the 200 kg vertical lift equivalent capacity.
Heavy Carton Stacking
Deposits large shipping containers onto high-tier warehouse racks, relying on the 33 mm cushions to soften end-of-stroke impacts.
Is the Airtac JSI Series Standard Cylinder JSI100X380S the Right Cylinder?
When sizing this 100 mm bore, verify if the 80 mm class (delivering 2513 N push at 0.5 MPa) is sufficient, or if you need to step up to the 125 mm bore for 6136 N. For this 380 mm stroke, external guide rails are highly recommended to prevent rod-bending under heavy side loads. Since air loss or a centered valve will cause the piston to drift, install an external rod lock or pilot-operated check valve if the load must be held in position. The included -S magnet pairs perfectly with CMSE/DMSE sensors, and mounting options span LB foot, FA/FB flange, CA/CB clevis, and TC trunnion.
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 JSI100X380S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it yields 5497 N push and 5003 N pull. The theoretical maximum 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, saving valuable machine space while retaining the same mounting flexibility.
