Airtac SED Double Rod Cylinder SED80X800
The AirTAC Airtac SED Double Rod Cylinder SED80X800 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 800mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X800
The AirTAC SED80X800 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a Ø25mm rod exits both end covers, the effective piston area is identical on extend and retract. It yields 2268N of output force each way at 0.5 MPa, ensuring perfectly balanced motion for demanding tasks.
This 800mm stroke unit features an extruded aluminum barrel without external tie rods. Field-adjustable air cushions at both ends absorb kinetic energy over a 36mm length. Note that this specific SKU lacks a piston magnet, meaning no CMSE or DMSE position sensing is possible without a model change.

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 SED80X800 Is Used
Pallet Transfer Reject
Uses the balanced 2268N force to push heavy pallets off a high-speed line. The twin rods prevent binding across the 800mm stroke during abrupt lateral redirects.
Web Guide Tensioning
Employs the rear rod end to mount a dancer arm cam. Equal force both ways maintains consistent tension on wide material webs without drift.
Press Feed Pusher
Drives a blank into a stamping press. The 3175N available at 0.7 MPa moves heavy steel blanks, while the double-rod design resists twisting under offset loads.
Is the Airtac SED Double Rod Cylinder SED80X800 the Right Cylinder?
Step down to the 63mm bore if your application only requires 1402N at 0.5 MPa, or step up to the 100mm bore for 3681N. The 80mm bore provides 2268N both ways, striking a balance for heavy loads. Choose this double-rod SED over a single-rod SE when you need superior anti-rotation resistance or want to mount a rear cam and sensor flag to drive a secondary mechanism.
When replacing an existing ISO 15552 cylinder, match the 80mm bore, 800mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). At 800mm of travel, external guide rails are critical to prevent side-load damage to the M20x1.5 rod threads. Plain air pressure will not hold position on failure; the piston drifts, so specify a BSED rod-lock variant if fail-safe holding is required.
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 SED80X800 FAQ
Because the double-rod design subtracts rod area on both sides, force is equal in both directions. It provides 2268N at 0.5 MPa, 3175N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
No. The adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. If power fails, the cylinder will drift. For fail-safe holding, use a BSED double-rod rod-lock cylinder or an external pilot-operated check valve.
