Airtac SED Double Rod Cylinder SED63X270
The AirTAC SED Double Rod Cylinder SED63X270 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 SED63X270
The AirTAC SED63X270 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63 mm bore and 270 mm stroke. Because a rod exits both ends, the effective piston area is identical in both directions, yielding an equal drive force of 1402 N each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring a clean profile for tight machinery layouts.
This unit uses a PT3/8 port and a 20 mm rod with an M16x1.5 thread. It includes field-adjustable air cushions at both ends to manage deceleration. Note that this specific SKU lacks a magnet (-S), so it cannot support CMSE or DMSE position sensors without modification.
Airtac SED Double Rod Cylinder SED63X270 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 SED63X270 Is Used
Servo Press Heads
Drives precision stamping heads with 1402 N both-way force, using the rear rod to mount a mechanical cam for secondary ejection operations.
Web Tracking Frames
Guides conveyor material edges via twin rods that prevent binding and rotation across the 270 mm stroke, ensuring smooth lateral correction.
Glass Panel Lifters
Lifts and lowers delicate glass sheets, relying on equal both-way speed and force to prevent sudden jerks during vertical positioning.
Is the Airtac SED Double Rod Cylinder SED63X270 the Right Cylinder?
When sizing this 63 mm bore, stepping down to the 50 mm bore drops the both-way force to 825 N at 0.5 MPa, while stepping up to the 80 mm bore increases it to 2268 N. Choose this double-rod SED over a single-rod SE when your application demands high anti-rotation stability, dual-side guidance, or needs to mount a rear cam and tooling. At 270 mm stroke, ensure external guides support the load to prevent side-loading bending forces on the twin 20 mm rods.
Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not hold position on air loss. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. As a true ISO 15552 cylinder, it drops in dimensionally for any standard ISO 15552 double-rod footprint using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
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 SED63X270 FAQ
The SED63X270 provides equal force in both directions due to its double-rod design. It delivers 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 provide superior anti-rotation guidance and allow the rear rod end to drive a secondary mechanism or sensor flag. It also ensures the extend and retract speeds are perfectly matched.
