Airtac SED Double Rod Cylinder SED50X80S
The AirTAC SED Double Rod Cylinder SED50X80S 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 80mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X80S
The AirTAC SED50X80S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 80mm stroke. Because a 20mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal force in both directions, generating 825 N at 0.5 MPa and 1154 N at 0.7 MPa.
Equipped with the -S magnet option, this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel contains no external tie rods, and field-adjustable air cushions at both ends manage kinetic energy. The rear rod extension is excellent for mounting a cam, driving a secondary mechanism, or providing dual-side load guidance.

| Port size | PT1/4 |
| 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, 30 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 (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 SED50X80S Is Used
PCB Lift Gates
Provides 825 N of equal both-way force to raise and lower delicate printed circuit board trays in wave soldering machines without rotational skew.
Dual-Side Grippers
Uses the through-rod design to actuate synchronized clamping jaws on both ends of an automotive machining fixture simultaneously.
Indexing Cams
Leverages the rear rod protrusion to drive a mechanical indexing cam in a packaging cartoner while the front rod executes the primary push stroke.
Is the Airtac SED Double Rod Cylinder SED50X80S the Right Cylinder?
Choose this 50mm bore when an application demands 825 N of bidirectional force at 0.5 MPa. If you need less power, the 40mm SED provides 528 N; stepping up to the 63mm bore yields 1402 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for lifting heavy parallel loads. Ensure you leave physical clearance at the rear cover for the protruding rod.
For position holding during air loss, note that a standard SED drifts; the adjustable cushions only decelerate near stroke end and do not lock the piston. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. To replace an existing ISO 15552 unit, match the 50mm bore, 80mm stroke, PT1/4 port, and preferred mounting from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 styles.
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 SED50X80S FAQ
The SED50X80S generates equal force in both extend and retract directions due to its double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and reaches a maximum of 168 kgf at 1.0 MPa.
A double-rod cylinder provides identical force and speed in both directions, which is critical for balanced reciprocating motions. The twin rods also offer superior anti-rotation resistance and allow the rear rod to drive secondary tooling or sensors.
