Airtac SED Double Rod Cylinder SED63X800S
The AirTAC SED Double Rod Cylinder SED63X800S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø63mm 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 SED63X800S
The AirTAC SED63X800S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 800mm stroke. Because a 20mm rod exits both end covers, the annulus area is identical on both sides, yielding exactly 1402N of force at 0.5 MPa in both extend and retract directions. The extruded aluminum barrel omits external tie rods, ensuring clean ISO 15552 dimensional interchangeability.
Equipped with a standard magnet (-S), this unit directly accepts CMSE reed and DMSE electronic sensors in the integrated barrel groove. The rear rod extension is perfect for mounting a secondary cam or limit flag to track position from the back of the machine. Field-adjustable air cushions at both ends tune deceleration for heavy 800mm traverses.

| Port size | PT3/8 |
| Rod thread | M16×1.5 |
| 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 |

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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SED63X800S Is Used
Long-Stroke Transfer Conveyor
Drives an 800mm pallet shift in a packaging line. The twin rods provide 1402N of equal force both ways, preventing chassis twist during rapid 30-800mm/s indexing.
Web Edge Guiding Mechanism
Steers a material web via a rear-rod cam. The double-rod design resists rotational torque, while DMSE electronic sensors track the 63mm piston position precisely.
Dual-Side Press Assembly
Actuates a clamping fixture from opposite sides simultaneously. The SED63X800S supplies 1962N at 0.7 MPa on both extend and retract, ensuring balanced clamping force.
Is the Airtac SED Double Rod Cylinder SED63X800S the Right Cylinder?
At 0.5 MPa, this 63mm bore delivers 1402N both ways. If your payload is lighter, the 50mm bore provides 825N, while stepping up to the 80mm bore yields 2268N. Choose this double-rod SED over a single-rod SE when the application demands anti-rotation stability, equal push/pull dynamics, or a rear rod to drive a secondary mechanism. Replacing an ISO 15552 unit requires matching the 63mm bore, 800mm stroke, PT3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
For an 800mm stroke, the extended rod length increases the lever arm on the piston. You must use external linear guides to support the load and prevent side-loading from bending the 20mm rod or damaging the seals. Note that a plain SED drifts on air loss; the adjustable cushion only decelerates near stroke end. For fail-safe holding, specify a BSED double-rod lock or external 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 SED63X800S FAQ
Because the double-rod design has a rod on both sides of the piston, the force is identical in both directions. It provides 1402N at 0.5 MPa, 1962N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods provide equal extend and retract forces, better load guidance against rotation, and a rear rod end for mounting secondary tooling or sensors. It is dimensionally interchangeable with other ISO 15552 profile cylinders and uses a PT3/8 port.
