Airtac SED Double Rod Cylinder SED50X90S
The AirTAC SED Double Rod Cylinder SED50X90S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø20mm piston rod exits BOTH ends of the Ø50mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 90mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X90S
The AirTAC SED50X90S is a double-acting, double-rod ISO 15552 profile cylinder engineered for equal bidirectional output. Because a 20mm rod occupies both piston faces, the annulus area matches on extend and retract, yielding a consistent 825 N of force each way at 0.5 MPa. The extruded aluminum barrel omits external tie rods, ensuring a clean profile that drops into standard ISO 15552 mounting interfaces.
Fitted with the -S magnet option, this unit directly supports CMSE reed and DMSE electronic sensors for mid-stroke position detection. The rear rod extension is highly valuable for driving secondary mechanisms or mounting a physical cam, while providing superior anti-rotation guidance for the load. Field-adjustable air cushions at both ends manage deceleration smoothly across the 30mm cushion stroke.

| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 90 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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, 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SED50X90S Is Used
Precision Grinding Slides
Drives a dual-side grinding fixture with 825 N of equal force, using the rear rod to maintain strict anti-rotation guidance for precision surface finishing.
Pallet Transfer Stops
Indexes a 90mm stroke stopper gate on a packaging line, utilizing the through-rod to mount a physical cam that triggers a downstream sensor.
PCB Edge Clamping
Secures circuit boards during routing by clamping from both ends simultaneously, ensuring perfectly centered holding with 1154 N at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED50X90S the Right Cylinder?
When sizing this 50mm bore, stepping down to the 40mm bore yields 528 N at 0.5 MPa, whereas stepping up to the 63mm bore provides 1402 N at 0.5 MPa. Choose this specific SED model over a single-rod SE when your application demands dual-side tooling, rear-rod sensing flags, or strict resistance to torsional twist. Note that while the adjustable end cushions decelerate the piston near stroke limits, a plain SED cannot hold position upon air loss; for fail-safe locking, consider the BSED double-rod lock variant or an external pilot-operated check valve. Replacement requires matching the 50mm bore, 90mm stroke, PT1/4 port, and your specific mounting accessory (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 SED50X90S FAQ
The SED50X90S provides equal force in both directions due to its double-rod design. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin-rod design guarantees identical extend and retract speeds and forces. The protruding rear rod is ideal for driving secondary mechanisms, mounting sensor flags, and offering superior load stability against rotation compared to a single-rod ISO 15552 cylinder.
