Airtac SED Double Rod Cylinder SED50X950S
The AirTAC SED Double Rod Cylinder SED50X950S 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 950mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X950S
The AirTAC SED50X950S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensions. A 20 mm rod extends from both end covers, yielding equal annulus areas and exactly 825 N of force each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile.
Equipped with a standard magnet (-S), this unit directly accepts CMSE reed or DMSE electronic sensors for mid-stroke positioning. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the rear rod end can drive a secondary mechanism or cam.
Airtac SED Double Rod Cylinder SED50X950S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X950S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 950 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 SED50X950S Is Used
Web Tensioning Frames
Drives a tensioning roller with 825 N both ways at 0.5 MPa, using the twin rods to prevent web skew during high-speed material feed.
Dual-Side PCB Milling
Mills both sides of a circuit board simultaneously using the 950 mm stroke, relying on the rear rod to carry a secondary cutting head.
Long-Stroke Strip Alignment
Straightens metal strip in a forming line over 950 mm, utilizing the anti-rotation properties of the double rod to maintain tool angle.
Is the Airtac SED Double Rod Cylinder SED50X950S the Right Cylinder?
At 950 mm stroke, this 50 mm bore yields 825 N both ways at 0.5 MPa. If your load is lighter, the 40 mm bore neighbor provides 528 N. For heavier thrust, step up to the 63 mm bore for 1402 N. Because the stroke exceeds 300 mm, external guide rails are strongly recommended to prevent sagging and side-load damage to the front and rear rod seals.
Choose this double-rod SED over a single-rod SE when you need anti-rotation guidance, simultaneous dual-side work, or rear-rod sensing. It uses a PT1/4 port and M16x1.5 rod thread. Note that a plain SED will drift on air loss; for fail-safe holding, use an AirTAC BSED double-rod lock cylinder.
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 SED50X950S FAQ
Because the double-rod design has equal piston areas on both sides, force is identical in extend and retract. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
Yes, the SED50X950S matches ISO 15552 / VDMA 24562 mounting dimensions. Just verify your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2) and ensure you have rear-rod clearance, as the rod protrudes both ends.
