Airtac SED Double Rod Cylinder SED100X270
The AirTAC Airtac SED Double Rod Cylinder SED100X270 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 270mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X270
The AirTAC SED100X270 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. A 25 mm rod exits both end covers, yielding an identical annulus area on each side. This means you get 3681 N of output force at 0.5 MPa in both extend and retract directions.
Because this SKU lacks the -S magnet option, it does not support CMSE or DMSE position sensing. The extruded aluminum barrel includes adjustable air cushioning at both ends to manage kinetic energy. Remember that the through-rod design increases overall length, so you must leave physical clearance at the rear for the protruding shaft.
Airtac SED Double Rod Cylinder SED100X270 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X270 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 270 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 SED100X270 Is Used
Servo Press Ram
Drives a precision stamping ram with 5153 N at 0.7 MPa. The twin-rod architecture prevents yaw during high-force downward pressing cycles.
Pallet Diverter
Pushes heavy pallets sideways off a main conveyor line. Equal 3681 N force in both directions ensures smooth retraction of the diverter arm.
Mold Transfer Cart
Actuates a dual-sided mold clamping mechanism. The rear rod end provides a stable mounting point for a mechanical cam flag.
Is the Airtac SED Double Rod Cylinder SED100X270 the Right Cylinder?
Choose this 100 mm bore when you need heavy bidirectional thrust without rotational drift. Stepping down to the 80 mm bore drops your both-way force to 2268 N at 0.5 MPa, while stepping up to 125 mm raises it to 5734 N. At 270 mm stroke, the extended rod length demands external guide rails to prevent side-loading damage to the M20x1.5 rod threads and front cover seals.
Unlike a single-rod SE cylinder, this double-rod unit drives a load from both ends simultaneously, providing superior anti-rotation stability for heavy tooling. A plain SED will drift on air loss, as the adjustable cushion only decelerates near stroke end rather than locking position. For fail-safe holding, consider a BSED double-rod rod lock or external pilot check valve. To match this ISO 15552 footprint for a replacement, verify the PT1/2 port, 270 mm stroke, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or 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 SED100X270 FAQ
Because the double-rod design occupies piston area on both sides, force is identical in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
Yes. The SED100X270 is dimensionally interchangeable per ISO 15552. Just match the 100 mm bore, 270 mm stroke, PT1/2 port, and mounting style. Note that the double-rod design requires extra rear clearance and omits FB, CA, CB, and CR mounts.
