Airtac SED Double Rod Cylinder SED80X700S
The AirTAC Airtac SED Double Rod Cylinder SED80X700S 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 700mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X700S
The AirTAC SED80X700S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. It features an extruded aluminum barrel without external tie rods. A Ø25 mm rod exits both end covers, yielding identical annulus areas. This equal force design outputs 2268 N in both extend and retract directions at 0.5 MPa.
Equipped with a standard magnet (-S), the rear rod end can mount a CMSE reed or DMSE electronic sensor flag. The twin rods provide dual-side guidance to resist load rotation. Adjustable air cushions at both ends decelerate the piston near stroke end, but do not lock position on air loss.
Airtac SED Double Rod Cylinder SED80X700S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED80X700S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 700 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 SED80X700S Is Used
Web Guiding Mechanism
Drives a 700 mm stroke correction roller with 2268 N both ways, using the twin rods to prevent web skew and maintain precise tracking.
Pallet Transfer Pusher
Pushes heavy pallets along a conveyor line. The equal both-way force ensures consistent 2268 N push and retract speeds for cycle stability.
Dual-Action Shuttle Gate
Alternates flow between two machine lanes. The rear rod operates a secondary cam while the front rod shifts the gate at 3175 N.
Is the Airtac SED Double Rod Cylinder SED80X700S the Right Cylinder?
The 80 mm bore yields 2268 N both ways at 0.5 MPa (3175 N at 0.7 MPa). If your drive needs less force, step down to the 63 mm bore providing 1402 N both ways. For heavier loads, step up to the 100 mm bore delivering 3681 N both ways. To replace an ISO 15552 cylinder, match the 700 mm stroke, PT3/8 port, and mounting from the SED set (Basic, FA, LB, TC, FTC, TCM1, TCM2). The SED omits FB, CA, CB, and CR mounts. For a 700 mm stroke, external guides are recommended to handle side loads. A plain SED drifts on air loss; for fail-safe holding, use a BSED double-rod lock.
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 SED80X700S FAQ
Because a rod exits both ends, the force is identical in both directions. It delivers 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 superior anti-rotation guidance and equal extend/retract forces. The protruding rear rod can also drive a secondary mechanism or carry a DMSE sensor flag, which a single-rod SE cannot do.
