Airtac SED Double Rod Cylinder SED80X150
The AirTAC Airtac SED Double Rod Cylinder SED80X150 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 150mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X150
The AirTAC SED80X150 is a double-acting, double-rod profile cylinder fully dimensionally interchangeable per the ISO 15552 standard. Because a 25 mm rod exits both end covers, the effective piston area is identical on extend and retract. It generates exactly 2268 N of force in both directions at 0.5 MPa, eliminating the thrust asymmetry found in single-rod units.
This unit features an extruded aluminum barrel without external tie rods and a PT3/8 port. Field-adjustable air cushioning at both ends manages end-of-stroke deceleration over a 36 mm length. This specific SKU lacks the -S magnet option, meaning it does not support CMSE or DMSE position sensing without modification.

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 SED80X150 Is Used
Web Guiding Mechanism
Drives a paper or film web guide with 2268 N of equal both-way force, using the twin 25 mm rods to keep the guiding roller perfectly parallel and prevent material wrinkling.
Multi-Station Transfer Die
Shifts sheet metal blanks between press stations. The rear rod extension actuates a secondary cam, synchronizing the 150 mm stroke transfer with the press cycle.
Equal-Power Clamping Fixture
Secures heavy automotive castings. The double-rod design ensures the clamp retracts with the same 2268 N authority as it extends, preventing workpiece ejection under vibration.
Is the Airtac SED Double Rod Cylinder SED80X150 the Right Cylinder?
Select this 80 mm bore when a task demands 2268 N of symmetrical thrust at 0.5 MPa (or 3175 N at 0.7 MPa). If your mechanism requires less force, the adjacent 63 mm bore yields 1402 N both ways. For heavier payloads, stepping up to the 100 mm bore provides 3681 N. The twin 25 mm rods provide superior anti-rotation guidance compared to a single-rod SE cylinder, and the extending rear rod can drive a secondary mechanism. Remember that an SED relies on air pressure; it will drift upon air loss. For fail-safe holding, specify a BSED double-rod lock or an external pilot-operated check valve. When replacing an ISO 15552 unit, match the 150 mm 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 SED80X150 FAQ
Because the double-rod design subtracts the 25 mm rod area from both sides of the piston, force is equal in both directions. It outputs 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
No. The adjustable air cushion at both ends only decelerates the piston near the 150 mm stroke limits; it is not a brake. If air loss occurs, the load will drift. For fail-safe position holding, use an AirTAC BSED double-rod lock cylinder or an external rod lock.
