Airtac JSID Double Rod Cylinder JSID50X900S

Delivering 825 N of equal thrust in both directions at 0.5 MPa, this 50 mm bore double-rod actuator uses a single piston with a rod exiting each cover. That symmetric layout creates an identical pressure area on both faces, meaning push and pull forces match exactly at 1154 N when running at 0.7 MPa. This translates to a safe working load of about 495 N, which is enough to vertically lift roughly 42 kg with a 2:1 safety margin. The extruded hard-anodized aluminum profile barrel keeps the unit more compact and noticeably shorter than an ISO 15552 cylinder of the same bore.

Because this is an -S variant, the piston carries a built-in magnet for direct mounting of CMSE or DMSE position switches into the side grooves. The G1/4 air port feeds the double-acting chambers, while adjustable 20.5 mm air cushions at both ends manage end-of-stroke deceleration. Note that this 900 mm stroke is a long extension; to prevent rod bending and premature seal wear, you must support the load with an external guide to absorb any lateral forces.
