Airtac SED Double Rod Cylinder SED80X55S
The AirTAC Airtac SED Double Rod Cylinder SED80X55S 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 55mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X55S
The AirTAC SED80X55S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract. This means you get exactly 2268 N of thrust and pull at 0.5 MPa, ensuring perfectly symmetrical force for demanding cycles.
This 80mm bore unit features a PT3/8 port and an M20x1.5 rod thread. The integrated -S magnet allows direct mounting of CMSE reed or DMSE electronic sensors into the barrel groove. Field-adjustable air cushions at both ends absorb kinetic energy near stroke limits, while the rear rod extension can drive a secondary mechanism or cam.

| 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 SED80X55S Is Used
Servo Press Dismantler
Uses the 2268 N equal both-way force to extract and insert heavy bearing races without reversing load characteristics.
Web Guide Mechanism
Leverages the twin 25mm rods for high torsional resistance, keeping a film tracking roller perfectly aligned.
Dual-Side Shuttle Drive
Drives a packaging carton transfer from both ends simultaneously, using the rear rod to trip a DMSE electronic sensor.
Is the Airtac SED Double Rod Cylinder SED80X55S the Right Cylinder?
Selecting this 80mm bore gives you 2268 N both ways at 0.5 MPa. If you need less force, the 63mm bore provides 1402 N. If your application requires more power, step up to the 100mm bore for 3681 N. Choose this double-rod SED over a single-rod SE when you need anti-rotation stability or rear-end tooling. Remember that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED rod-lock cylinder or an external pilot-operated check valve. To replace an existing ISO 15552 unit, match the 80mm bore, 55mm stroke, PT3/8 port, and your preferred mounting (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 SED80X55S FAQ
Because the 25mm rod occupies both piston sides, force is equal 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-rod design prevents piston rotation and provides identical force both ways. It also leaves a rear rod extension available for mounting a cam or sensor flag, which is impossible on a standard single-rod SE cylinder.
