The AirTAC SED Double Rod Cylinder SED63X155 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 155mm, PT3/8 ports, adjustable cushioning.
The AirTAC SED63X155 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a 20mm rod exits both end covers, the annulus area is identical on extend and retract. This gives you exactly 1402N of output force in both directions at 0.5 MPa.
This SKU ships without a magnet, so it is ready for pure mechanical drive duties rather than position sensing. The extruded aluminum barrel has no external tie rods, and you can fine-tune the 36mm adjustable air cushions at both ends to soften end-of-stroke impact.

Because a rod exits both ends, the effective piston area — and therefore the force — is identical on extend and retract. Actual usable force is lower than theoretical; size with a safety margin.

Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B). Seals: TPU (blank) / FKM high-temp (H) / NBR (N). Thread: PT (blank) / G. Mounting (SED): Basic, LB, FA, TC, FTC, TCM1, TCM2. Related: SE (single rod), SEJ (double-rod adjustable stroke), BSED (double-rod rod lock).
Drives a parallel steering roller in a film converting line. The twin rods prevent chassis yaw, applying 1402N of perfectly balanced force to keep the material web tracking straight.
Raises and lowers a transfer shuttle in a packaging machine. The rear rod end acts as a stable cam follower, ensuring the 155mm vertical lift remains perfectly parallel under load.
Synchronizes a clamping action on an CNC fixture. Equal push and pull force guarantees that the workpiece is centered without rotational drift during machining.
Step down to a 50mm bore if you only need 825N both ways at 0.5 MPa, or step up to an 80mm bore for 2268N. Choose this 63mm SED over a single-rod SE when your mechanism requires twin-side guidance to resist rotation, or when you need to mount a cam on the rear rod. Note that a plain SED will drift on air loss; the cushions only decelerate near stroke end. For fail-safe holding, use a BSED rod lock. To match this ISO 15552 footprint, confirm your 155mm stroke, PT3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Quick checklist
Because the double-rod design occupies equal piston area on both sides, force is identical in both directions: 1402N at 0.5 MPa, 1962N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes. The SED63X155 is a true ISO 15552 profile cylinder. As long as you match the 63mm bore, 155mm stroke, PT3/8 port, and mounting style, it serves as a direct dimensional replacement for any standard ISO 15552 double-rod cylinder.
