Airtac SED Double Rod Cylinder SED40X50S
The AirTAC Airtac SED Double Rod Cylinder SED40X50S 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 50mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED40X50S
The AirTAC SED40X50S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. Because a 16mm rod exits both end covers, the annulus area is identical on extend and retract. It delivers 528N of output force in both directions at 0.5 MPa.
This through-rod design provides superior anti-rotation guidance for moving loads. The rear rod extension can mount a cam or sensor flag, and the included -S magnet works directly with CMSE reed and DMSE electronic sensors. Field-adjustable air cushions at both ends decelerate the 50mm stroke without fixed bumpers.
Airtac SED Double Rod Cylinder SED40X50S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 50 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 SED40X50S Is Used
PCB Edge Guiding
Provides 528N of equal both-way force to align circuit boards during conveyor transport, using the rear rod for a tracking flag.
Shuttle Transfer
Drives a 50mm pick-and-place jaw with twin rods, ensuring precise anti-rotation handling for small electronic components.
Valve Capping
Presses fittings onto pneumatic valve bodies with 739N at 0.7 MPa, allowing a cam on the rear rod to trigger the next station.
Is the Airtac SED Double Rod Cylinder SED40X50S the Right Cylinder?
Selecting this 40mm bore gives you 528N both-way force at 0.5 MPa. If you need less power, the 32mm bore offers 345N. For heavier demands, the 50mm bore provides 825N. Choose the SED40X50S over a single-rod SE when a machine requires twin-side tooling or rear-rod position flagging. Remember that air pressure loss causes drift; a plain SED does not hold position. For fail-safe locking, specify a BSED double-rod lock cylinder. At 50mm stroke, side loads are minimal, but external guides help when pushing off-center.
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 SED40X50S FAQ
Because the double-rod design subtracts rod area on both sides, force is equal in both directions: 528N at 0.5 MPa, 739N at 0.7 MPa, and a maximum of 108kgf at 1.0 MPa.
Yes, the SED40X50S is dimensionally interchangeable per ISO 15552. Match the 40mm bore, 50mm stroke, PT1/4 port, and mounting interface for a drop-in replacement.
