Airtac SED Double Rod Cylinder SED50X280S
The AirTAC SED Double Rod Cylinder SED50X280S 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 280mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X280S
The AirTAC SED50X280S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is identical on extend and retract. It delivers an equal 825 N of drive force in both directions at 0.5 MPa. The extruded aluminum barrel has no external tie rods, ensuring a clean profile.
This 50 mm bore unit includes the -S magnet option for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the barrel groove. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the rear rod end can drive a secondary mechanism or carry a limit flag.

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 SED50X280S Is Used
PCB Edge Guiding
Drives twin guide rails to center electronic boards. The 825 N equal both-way force ensures perfectly symmetric clamping without rotational drift over the 280 mm travel.
Dual-Side Pallet Transfer
Pushes and retracts a pallet from two opposing points simultaneously. The double-rod architecture provides stable bidirectional transfer at speeds up to 800 mm/s.
Film Roll Tensioning
Applies constant tension to a web via a rear-rod cam. The matching extend and retract areas maintain precise 825 N pressure regardless of the motion direction.
Is the Airtac SED Double Rod Cylinder SED50X280S the Right Cylinder?
Choose this 50 mm bore when you need 825 N of equal both-way force at 0.5 MPa. If your application is lighter, the 40 mm bore provides 528 N both ways. For heavier loads, stepping up to the 63 mm bore yields 1402 N both ways. The twin-rod design offers superior anti-rotation guidance compared to a single-rod SE cylinder, making it ideal for 280 mm strokes that require external guides to prevent side-loading wear.
To replace an existing ISO 15552 cylinder, match the 50 mm bore, 280 mm stroke, PT1/4 port, and mounting style. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the air cushion only decelerates the load; it does not hold position on air loss. For fail-safe holding, use an external rod lock or a BSED double-rod 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 SED50X280S FAQ
Because the rod occupies both sides of the piston, force is equal in both directions. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin rods provide equal force and speed on extend and retract, while offering better load guidance against rotation. The rear rod can also mount a sensor flag or drive a second mechanism, but you must leave clearance for the protruding rear rod.
