Airtac SED Double Rod Cylinder SED80X50S
The AirTAC Airtac SED Double Rod Cylinder SED80X50S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 50mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X50S
The AirTAC SED80X50S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A Ø25mm rod exits both end covers, yielding an identical annulus area on each side. This means you get 2268 N of output force at 0.5 MPa in both extend and retract directions.
The integrated -S magnet enables position detection using DMSE electronic or CMSE reed switches. Because the rear rod protrudes from the back cover, you can mount a secondary cam or sensor flag directly onto it to trigger downstream logic without taking up primary tooling space.
Airtac SED Double Rod Cylinder SED80X50S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X50S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 mm |
| Configuration | Double rod, double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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 |
| Max stroke | Up to 1500 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X50S Is Used
Servo Press Peening
Drives a reciprocating peen head with 2268 N of balanced force, using the rear rod end to trip a physical limit cam at the start of every stroke.
Panel Alignment Jig
Pushes and pulls an alignment blade with equal 0.5 MPa force, leveraging the twin rods to prevent yaw during heavy sheet-metal positioning.
Dual-Side Transfer Arm
Actuates a transfer arm that shuttles parts between two conveyors, using the symmetrical rod layout to maintain speed parity in both directions.
Is the Airtac SED Double Rod Cylinder SED80X50S the Right Cylinder?
Choose this 80mm bore when you need 2268 N of equal both-way force at 0.5 MPa. Stepping down to the 63mm bore drops the output to 1402 N, while moving up to the 100mm bore increases it to 3681 N. The twin-rod design inherently resists torsional rotation better than a single-rod SE cylinder, making it ideal for guided lifts. Note that a plain SED will drift on air loss; for fail-safe holding, select a BSED or use an external rod lock. To replace an existing ISO 15552 unit, match the 80mm bore, 50mm stroke, PT3/8 port, and mounting style (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 SED80X50S FAQ
Because the double-rod design occupies piston area on both sides, force is identical in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
The twin rods provide equal extend and retract force, prevent torsional load rotation, and give you a protruding rear rod end for mounting secondary cams or sensor flags.
