Airtac SED Double Rod Cylinder SED63X20
The AirTAC SED Double Rod Cylinder SED63X20 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 20mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X20
The AirTAC SED63X20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 20mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding equal force and speed in both directions at 1402 N each way at 0.5 MPa. The extruded aluminum barrel includes integrated sensor grooves, though this specific SKU lacks the -S magnet option for CMSE or DMSE position sensing.
This short-stroke design uses a 20mm diameter rod with an M16x1.5 thread on both ends and PT3/8 ports. The twin rods provide superior load guidance against rotation, while the field-adjustable air cushion at both ends decelerates the piston near stroke ends. Remember to leave rear-rod clearance, as the overall length is longer than a single-rod SE cylinder.

| 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 SED63X20 Is Used
Panel Bending Press
Provides 1402 N of equal both-way force to clamp sheet metal in a short 20mm stroke, using the twin rods to prevent jaw rotation during precision bending.
Shuttle Transfer Gate
Uses the rear rod end to drive a secondary cam mechanism while guiding the load against rotation, ensuring perfectly synchronized part transfer.
PCB Component Inserter
Drives a pick-and-place head over a 20mm travel with identical extend and retract speeds, maintaining strict dynamic balance for delicate electronics assembly.
Is the Airtac SED Double Rod Cylinder SED63X20 the Right Cylinder?
Select this 63mm bore when you need 1402 N of both-way force at 0.5 MPa for compact 20mm stroke movements. If your application requires less force, step down to the 50mm bore providing 825 N both ways. For heavier drives, step up to the 80mm bore delivering 2268 N both ways. Choose this double-rod SED over a single-rod SE when your machine demands anti-rotation guidance, dual-side tooling, or a rear-rod cam. Note that a plain SED does not hold position on air loss; for fail-safe holding, consider a BSED or an external rod lock. As a direct ISO 15552 replacement, match the 63mm bore, 20mm stroke, PT3/8 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SED63X20 FAQ
The SED63X20 provides equal force in both directions because of its double-rod design. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
The twin rods exiting both ends offer superior load guidance against rotation and allow the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552, but omits FB, CA, CB, and CR mounts.
