Airtac SED Double Rod Cylinder SED50X90
The AirTAC SED Double Rod Cylinder SED50X90 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 SED50X90
The AirTAC SED50X90 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 90mm stroke. Because a 20mm rod exits both ends, the effective piston area is identical in both directions, yielding exactly 825 N of force each way at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring clean integration and true ISO 15552 dimensional interchangeability.
This unit lacks the -S magnet option, so it has no position sensing on this SKU. Field-adjustable air cushions at both ends (30mm cushion length) allow precise deceleration near stroke extremes. Remember that overall length is longer than a single-rod SE cylinder, so you must leave rear-rod clearance for the protruding shaft.
Airtac SED Double Rod Cylinder SED50X90 Technical Specifications

|---|---|
| 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 SED50X90 Is Used
Web Guiding Mechanism
Leverages the 825 N equal both-way force to tension and steer packaging film webs without rotational drift, using the rear rod for a tensioning cam.
Dual-Side Transfer Gate
Pushes pallets from both ends of a conveyor line smoothly, relying on the twin 20mm rods to prevent binding during the 90mm transfer stroke.
PCB Depaneling Saw Feed
Feeds a cutting blade with constant 825 N force in both directions, ensuring clean cuts where the rear rod can mount a physical limit flag.
Is the Airtac SED Double Rod Cylinder SED50X90 the Right Cylinder?
Choose this 50mm bore when you need 825 N both ways at 0.5 MPa. If your load is lighter, step down to the 40mm bore for 528 N; if heavier, step up to the 63mm bore for 1402 N. Select the double-rod SED over a single-rod SE when your application requires dual-side guidance, anti-rotation stability, or a rear rod to mount a cam and drive a secondary mechanism.
This SKU uses a PT1/4 port and M16x1.5 rod thread. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, intentionally omitting FB, CA, CB, and CR. Note that the adjustable air cushion only decelerates the load; it does not hold position on air loss. For fail-safe holding, use a BSED double-rod rod lock or external pilot-operated check valve.
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 SED50X90 FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
A double-rod cylinder provides equal extend and retract forces, better load guidance against rotation, and a rear rod exit for mounting secondary cams or sensors. It drops in for any ISO 15552 footprint but requires rear-rod clearance.
