Airtac SED Double Rod Cylinder SED63X185
The AirTAC SED Double Rod Cylinder SED63X185 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 185mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X185
The AirTAC SED63X185 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimension standard. Because a rod extends from both end covers, the effective piston area is identical on extend and retract. This cylinder generates exactly 1402 N of thrust each way at 0.5 MPa. It uses an extruded aluminum barrel with no external tie rods.
This specific SKU lacks the internal magnet option, meaning it cannot host CMSE or DMSE position sensors without modification. The rear rod protrusion allows you to mount a mechanical cam or secondary tooling directly opposite the primary work end, doubling your actuation points from one cylinder body.

| Port size | PT3/8 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C (0–150 °C with FKM seals) |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 36 mm |

Specifications follow the official AirTAC SED datasheet and ISO 15552 / VDMA 24562 dimensions. Confirm against the product label before installation. Port options: PT (standard) / G (BSPP).
Theoretical Output Force (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 kgf |
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.

Where the Airtac SED Double Rod Cylinder SED63X185 Is Used
Web Edge Guiding
Provides 1402 N of equal bidirectional force to steer material webs, using the twin rods to prevent binding during rapid reversing.
Shuttle Transfer
Drives a dual-sided pick-and-place shuttle where the rear rod mounts a secondary cam, keeping speed and force identical both ways.
Indexing Gate
Actuates a heavy sorting gate on a packaging line, relying on the 63mm bore's anti-rotation properties and 36mm adjustable cushioning.
Is the Airtac SED Double Rod Cylinder SED63X185 the Right Cylinder?
At 0.5 MPa, this 63mm bore yields 1402 N in both directions. If you need less force, step down to the 50mm bore (825 N both ways). If your payload is heavier, move up to the 80mm bore (2268 N both ways). Choose this double-rod SED over a single-rod SE when your mechanism demands high torsional rigidity and resistance to load rotation, or when you must drive a secondary mechanism off the rear rod end.
Remember that a standard SED cannot hold position upon air loss; the piston will drift. For fail-safe holding, consider the BSED series rod-lock cylinder or an external pilot-operated check valve. To replace an existing ISO 15552 unit, match the 63mm bore, 185mm stroke, PT3/8 port, and mounting style (available in Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Quick checklist
- ✓ Equal force/speed both directions needed?
- ✓ Back-rod space for tooling or a flag
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Support both rod ends; avoid side load.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SED Double Rod Cylinder SED63X185 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods offer superior resistance to side-load rotation and allow you to mount tooling, cams, or secondary mechanisms to the rear rod end. The SED is dimensionally interchangeable per ISO 15552, but omits the FB, CA, CB, and CR mounting styles.
