Airtac SED Double Rod Cylinder SED50X230
The AirTAC SED Double Rod Cylinder SED50X230 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 230mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X230
The AirTAC SED50X230 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 230mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding perfectly equal force in both directions—exactly 825N at 0.5MPa and 1154N at 0.7MPa. The extruded aluminum barrel eliminates external tie rods while maintaining strict ISO 15552 dimensional interchangeability.
This unit lacks the -S magnet option, meaning it has no onboard position sensing out of the box. The rear rod extension can drive a secondary mechanism or mount a physical cam, while field-adjustable air cushions at both ends (30mm stroke length) let you fine-tune end-of-stroke deceleration for moving loads.

| 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 |

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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X230 Is Used
PCB Depaneling Saw
Drives a circular saw blade with 825N of equal force in both directions, using the rear rod to mount a physical cam that triggers a dust extraction hood.
Pallet Transfer Pusher
Uses the twin rods' anti-rotation property to push heavy pallets straight on a conveyor line, ensuring the pusher plate stays perfectly perpendicular.
Pick-and-Place Gantry
Mounts to a dual-rail gantry where the symmetric 1154N force at 0.7MPa and double-ended guidance prevent binding during rapid vertical and horizontal part transfers.
Is the Airtac SED Double Rod Cylinder SED50X230 the Right Cylinder?
When sizing this 50mm bore, note the 40mm bore provides 528N and the 63mm bore provides 1402N (both at 0.5MPa, both directions). Choose the SED50X230 when your application requires exactly 825N of symmetric force and a 230mm stroke. Unlike a single-rod SE cylinder, this double-rod design uses twin guidance to resist side loads and prevent piston rotation, making it superior for driving synchronized tooling or external gantries.
Because the 230mm stroke exceeds 300mm is false here, standard side-load rules apply, but always support long strokes with external guides. Remember that a plain SED does not hold position on air loss—the piston drifts without pressure. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated check valve. To replace an ISO 15552 cylinder, match the 50mm bore, 230mm stroke, PT1/4 port, and desired mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2—note FB, CA, CB, and CR are omitted).
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 SED50X230 FAQ
Because it is a double-rod cylinder, the force is identical in both directions. It provides 825N at 0.5 MPa, 1154N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The double-rod design ensures equal force and speed on extend and retract, while the twin rods provide superior anti-rotation guidance for the load. The rear rod can also be used to mount a cam or drive a secondary mechanism.
