The AirTAC Airtac JSI Series Standard Cylinder JSI100X520S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 520mm 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.
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore JIS-standard profile cylinder is built for heavy-duty positioning. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the unit shorter and more compact than an ISO 15552 cylinder of the same bore. The internal two-way piston seal retains grease, ensuring low-friction operation over a long service life.
Because the SKU includes the -S suffix, a built-in piston magnet is present, allowing CMSE or DMSE electronic switches to drop directly into the side sensor grooves for position detection. 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 unit features a G1/2 air port, an M26x1.5 rod-end thread, and adjustable 33 mm air cushions at both ends to decelerate the payload smoothly.

Pushes heavy loaded pallets weighing up to 200 kg onto a secondary packaging line using the 520 mm stroke.
Provides the robust 3927 N push force required to eject dense plastic automotive interior panels from a mold cavity.
Actuates a heavy materials handling lift gate, moving components between floor levels while external guides absorb side loads.
When sizing this 100 mm bore actuator, compare your actual load against its 3927 N push and 3574 N pull figures at 0.5 MPa. If your application requires less force, the smaller 80 mm bore offers 2513 N push, while stepping up to the 125 mm bore yields 6136 N. For this specific 520 mm stroke configuration, external guide rails are strongly recommended to prevent rod bending and premature seal wear under side loading. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, or TC/TCM1/TCM2 trunnion brackets.
Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it does not function as a brake. If the air supply is lost or the valve is centered, the piston will drift. To safely hold a suspended load, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 100 mm bore model uses a G1/2 air port and generates 3927 N push / 3574 N pull at 0.5 MPa, and 5497 N push / 5003 N pull at 0.7 MPa. The theoretical maximum force is 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 bore. It uses an extruded hard-anodized aluminum barrel with no external rods, and the included -S magnet allows CMSE or DMSE switches to be fitted directly into the side grooves.
