Airtac SED Double Rod Cylinder SED40X600S
The AirTAC Airtac SED Double Rod Cylinder SED40X600S 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 600mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X600S
The AirTAC SED40X600S is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetrical load handling. Because a 16mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal 528 N of force each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring a clean profile that drops directly into standard ISO 15552 mounting interfaces.
Fitted from the factory with a magnetic piston (-S), this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke confirmation. The rear rod extension is ideal for driving a secondary mechanism, mounting a limit flag, or providing dual-side guidance to resist torsional twist. Field-adjustable air cushions at both ends manage deceleration across the 600mm travel.

| 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 |

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 SED40X600S Is Used
Pallet Transfer Pusher
Drives a 90-degree pallet diverter on a packaging line, using the equal 528 N both-way force to push and retract loads smoothly without speed variation.
Web Guiding Mechanism
Utilizes the twin-rod anti-rotation properties to adjust a film web guide, ensuring the rear rod can safely mount a cam without deflection.
Dual-Action Pick & Place
Actuates a gripper from the front rod while the rear rod simultaneously triggers a DMSE electronic sensor, coordinating a 600mm parts transfer.
Is the Airtac SED Double Rod Cylinder SED40X600S the Right Cylinder?
Selecting this 40mm bore provides a balanced 528 N both-way force at 0.5 MPa. If your application requires less thrust, stepping down to the 32mm bore yields 345 N both ways; stepping up to the 50mm bore provides 825 N both ways. The double-rod design is specifically chosen over a single-rod SE when the load demands high anti-rotation resistance or requires actuation from both ends simultaneously.
For a 600mm stroke, external guide rails are strongly recommended to prevent side-loading damage to the 16mm rod and front cover. Note that a plain SED does not hold position upon air loss; the piston will drift. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. When replacing an existing ISO 15552 cylinder, verify the 40mm bore, 600mm stroke, PT1/4 port, 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 SED40X600S FAQ
The double-rod design provides equal force in both directions. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and reaches a maximum of 108 kgf at 1.0 MPa.
The twin rods provide superior anti-rotation resistance and allow the rear rod to drive a secondary mechanism or sensor flag. Additionally, the effective area is balanced, ensuring extend and retract speeds remain identical.
