Airtac SED Double Rod Cylinder SED100X750
The AirTAC Airtac SED Double Rod Cylinder SED100X750 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 750mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X750
The AirTAC SED100X750 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional standard. Because a 25mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding a true bidirectional force of 3681 N at 0.5 MPa. It uses a PT1/2 port and an M20x1.5 rod-end thread. This extruded aluminum barrel design omits external tie rods, relying instead on integrated sensor grooves.
This 750mm stroke unit lacks the -S magnet option, meaning no CMSE or DMSE position sensors can be mounted on this specific SKU. The rear rod protrusion is ideal for driving a secondary mechanism or mounting a cam, while the twin rods provide superior anti-rotation guidance. Field-adjustable air cushions at both ends decelerate the load near stroke completion.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 750 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 |

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 SED100X750 Is Used
CNC Lathe Loader
Drives a dual-gripper arm to feed bar stock into a lathe. The twin rods prevent the heavy 3681 N push force from twisting the arm, while the rear rod trips a mechanical limit switch.
Pallet Transfer Gate
Shifts a 750mm conveyor lane diverter. The equal extend and retract force ensures smooth, balanced routing of heavy pallets without speed discrepancies between directions.
Press Ejection System
Ejects formed parts from a hydraulic press using both rod ends. The rear rod simultaneously pushes a completed part into a chute while the front rod clears the die.
Is the Airtac SED Double Rod Cylinder SED100X750 the Right Cylinder?
Select this 100mm bore when you need 3681 N of equal both-way force at 0.5 MPa. If you need less force, step down to the 80mm bore (2268 N both ways); if you need more, step up to the 125mm bore (5734 N both ways). Choose this double-rod SED over a single-rod SE when your application requires dual-side guidance to prevent load rotation, or when you need to actuate a secondary mechanism from the rear rod end.
When replacing an ISO 15552 cylinder, match the 100mm bore, 750mm stroke, PT1/2 port, and mounting style (available in Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that this 750mm stroke exceeds 300mm, so external guide rails are recommended to prevent excessive side loads from bending the 25mm rods. A plain SED does not hold position on air loss; for fail-safe locking, use a BSED double-rod 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 SED100X750 FAQ
The SED100X750 provides equal force in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
Yes, the SED100X750 is dimensionally interchangeable per ISO 15552. Just match the mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) and ensure you leave clearance for the rear rod, as the overall length is longer than a single-rod cylinder.
