Airtac SED Double Rod Cylinder SED63X270S
The AirTAC SED Double Rod Cylinder SED63X270S 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 270mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED63X270S
The AirTAC SED63X270S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 270mm stroke. Because a rod exits both end covers, the annulus area is identical on both sides, yielding equal force and speed in extend and retract. You get 1402 N of thrust each way at 0.5 MPa, and 1962 N at 0.7 MPa.
Equipped with a standard magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The extruded aluminum barrel includes adjustable air cushions at both ends (36mm cushion length) to decelerate loads near stroke limits, while the PT3/8 ports supply air efficiently.
Airtac SED Double Rod Cylinder SED63X270S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 270 mm |
| Configuration | Double rod, double acting |
| 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 |
| 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 (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 SED63X270S Is Used
Multi-Station Machining
Drives dual opposing clamps simultaneously using 1962 N at 0.7 MPa, ensuring parts stay perfectly centered during milling.
Pallet Transfer Pusher
Uses the rear rod to trip a limit flag while the front rod pushes pallets, leveraging equal 1402 N force at 0.5 MPa both ways.
Web Guide Mechanism
Twin 20mm rods resist rotational torque on web-guiding rollers, maintaining precise edge alignment in continuous material processing.
Is the Airtac SED Double Rod Cylinder SED63X270S the Right Cylinder?
Stepping down to the 50mm bore drops your both-way force to 825 N at 0.5 MPa, whereas stepping up to the 80mm bore raises it to 2268 N. Choose this 63mm size when your application requires roughly 1.4 to 2.0 kN of bidirectional thrust. The twin rods provide superior anti-rotation guidance and allow mounting a rear cam or secondary tooling. Remember, an SED does not hold position on air loss; for fail-safe locking, consider a BSED rod-lock cylinder or external clamp. At 270mm stroke, ensure external guides support any heavy lateral loads to protect the 20mm rods.
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 SED63X270S FAQ
The double-rod design provides equal force in both directions: 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and a maximum of 286 kgf at 1.0 MPa.
Yes. The SED63X270S is dimensionally interchangeable per ISO 15552 / VDMA 24562 profile standards. Just match the 63mm bore, 270mm stroke, PT3/8 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
