Airtac SED Double Rod Cylinder SED40X800S
The AirTAC Airtac SED Double Rod Cylinder SED40X800S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø16mm piston rod exits BOTH ends of the Ø40mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 800mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X800S
The AirTAC SED40X800S is a double-acting, double-rod ISO 15552 profile cylinder. A 16mm rod exits both end covers, yielding identical annulus areas so thrust is strictly equal in extend and retract—528 N at 0.5 MPa both ways.
Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the extruded aluminum barrel omits external tie rods for a clean ISO 15552 footprint.
Airtac SED Double Rod Cylinder SED40X800S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED40X800S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 800 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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, 30 mm |
| Max stroke | Up to 1200 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SED40X800S Is Used
Pick-and-Place Grippers
Provides 528 N of equal both-way force for transferring parts, using the rear rod end to mount a synchronized second gripper jaw.
Web Guiding Mechanisms
Twin rods resist rotational torque while adjusting material webs, ensuring precise tracking without torsional drift.
Sorting Diverter Arms
Drives dual-sided diverter gates simultaneously at 30-800 mm/s, using the through-rod to actuate a secondary lane.
Is the Airtac SED Double Rod Cylinder SED40X800S the Right Cylinder?
Stepping down to the 32mm bore yields 345 N at 0.5 MPa, while stepping up to the 50mm bore provides 825 N. Choose this 40mm bore when your mechanism needs exactly 528 N of bidirectional force. The twin rods prevent rotation and allow mounting a rear cam or secondary tooling.
At 800mm stroke, the extended rod length demands external load guides to prevent side-loading damage. Note that air cushions only decelerate; they do not hold position on air loss. For fail-safe holding, use a BSED double-rod lock or external pilot-operated check valve. Replacement match: 40mm bore, 800mm stroke, PT1/4 port, -S magnet.
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 SED40X800S FAQ
Because the double rods occupy both piston sides, force is identical in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a maximum of 108 kgf at 1.0 MPa.
Yes. The SED40X800S is dimensionally interchangeable per ISO 15552 / VDMA 24562. Match the 40mm bore, 800mm stroke, PT1/4 port, and mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2) for a drop-in fit.
