Airtac SED Double Rod Cylinder SED80X950
The AirTAC Airtac SED Double Rod Cylinder SED80X950 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø80mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 950mm, PT3/8 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED80X950
The AirTAC SED80X950 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional standard. Because a Ø25 mm rod extends from both end covers, the annular piston area is identical on both sides. This means the cylinder outputs exactly 2268 N of thrust in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, and field-adjustable air cushions at both ends decelerate the load near stroke extremes.
This 950 mm stroke unit features a PT3/8 port and an M20x1.5 rod-end thread. The twin-rod architecture provides superior load guidance against torsion and rotation. The rear rod extension can be used to mount a cam or drive a secondary mechanism. Note that this specific SKU lacks the -S magnet option, so it does not support CMSE or DMSE position sensing without modification.

| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| 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, 36 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SED80X950 Is Used
Web Guide Mechanism
Uses the 3175 N both-way force at 0.7 MPa to steer heavy paper or film webs, relying on the twin rods to prevent chassis rotation during high-speed shifting.
Shuttle Transfer Car
Drives a 950 mm transfer carriage between machining stations, utilizing the rear rod end to mechanically trigger a pneumatic limit valve at each stop.
Mold Press Extraction
Pushes and pulls heavy injection molds out of a press bed with equal 2268 N force at 0.5 MPa, ensuring symmetric extraction without tipping the heavy tool.
Is the Airtac SED Double Rod Cylinder SED80X950 the Right Cylinder?
Selecting this 80 mm bore yields a bidirectional force of 2268 N at 0.5 MPa (3175 N at 0.7 MPa). If your application requires less force, the adjacent 63 mm bore provides 1402 N at 0.5 MPa. For heavier loads, the 100 mm bore provides 3681 N at 0.5 MPa. The double-rod design is preferred over a single-rod SE when you need equal push and pull speeds, resistance to piston rotation, or a rear shaft to mount external tooling.
At a 950 mm stroke, the extended rod length amplifies side-load leverage. You must use external linear guides to prevent binding and premature seal wear. Remember that the adjustable air cushion only decelerates the load near the stroke ends; it does not hold position. If air pressure drops, the piston will drift. For fail-safe holding, use an external pilot-operated check valve or a BSED double-rod lock cylinder. This unit is a direct dimensional drop-in for any ISO 15552 mounting interface using Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
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 SED80X950 FAQ
Because the double-rod design subtracts the rod area on both sides, the output force is equal in both directions: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and a maximum of 463 kgf at 1.0 MPa.
Yes. The SED80X950 is dimensionally interchangeable per ISO 15552 profile standards. You can use the same Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting hardware, provided you leave rear-rod clearance for the protruding second shaft.
