The AirTAC Airtac JSID Double Rod Cylinder JSID100X500S is a genuine double acting, double rod 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.
Delivering 3574 N of thrust in both directions at 0.5 MPa, this double-acting profile cylinder uses a single piston with a rod exiting both ends. The symmetric layout prevents rotation and provides a stable load path. It yields a safe working load of about 2144 N, which translates to lifting roughly 182 kg vertically with a 2:1 margin. Built to JIS standards, the hard-anodized aluminum body is significantly shorter than a same-bore ISO 15552 unit.
This 100 mm bore variant features a 500 mm stroke, a 32 mm rod, and a G1/2 port. The -S suffix denotes a built-in piston magnet for CMSE/DMSE switches that mount directly into the side grooves. Adjustable 33 mm air cushions at both ends absorb kinetic energy near stroke end, though a plain cylinder drifts on air loss, so fit an external rod lock for held loads.

Double-rod: the rod passes through both covers, so output force is equal in both directions.

Drives two opposing machining heads simultaneously using both rod ends, ensuring perfectly synchronized cutting cycles.
Pushes a diverter blade from either side without twisting, keeping product flow aligned across the belt width.
Lifts loads up to 182 kg with a 2:1 safety margin, using the equal both-ways force to raise and lower smoothly.
Flanking this 100 mm bore are the 80 mm (2268 N) and 125 mm (5734 N) sizes, both delivering equal push and pull forces at 0.5 MPa. Choose a double-rod design when your mechanism demands anti-rotation guidance, twin tooling operation from one actuator, or a sensor cam at the back end. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke generates leverage, always support the load with external guides to prevent rod bending and premature seal wear.
Quick checklist
Force is equal both ways: 3574 N at 0.5 MPa, 5003 N at 0.7 MPa, and a theoretical max of 729 kgf at 1.0 MPa. It operates at 0.15-1.0 MPa, runs at 30-800 mm/s, and uses a G1/2 port with a 32 mm rod.
The -S indicates a built-in piston magnet. This allows CMSE or DMSE reed and electronic switches to drop into the side barrel grooves for precise position detection at either end of the 500 mm stroke.
