Airtac SED Double Rod Cylinder SED50X750S
The AirTAC SED Double Rod Cylinder SED50X750S 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 750mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X750S
The AirTAC SED50X750S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 750mm stroke. Because a 20mm rod exits both end covers, the effective piston area is identical in both directions, yielding an equal force of 825 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
Fitted with the -S magnet option, this unit directly supports rear-side electronic tracking via DMSE or reed CMSE sensors. Field-adjustable air cushioning at both ends provides tailored deceleration near stroke limits, while the M16x1.5 rod threads and PT1/4 ports simplify integration into your existing pneumatic infrastructure.

| 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 |

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 SED50X750S Is Used
Web Edge Guiding
Provides 825 N of equal bidirectional force to steer wide film or paper webs, using the rear rod end to mount a cam-follower for immediate tension feedback.
Pallet Transfer Pusher
Drives a 750mm stroke transfer carriage on a packaging line, where the twin 20mm rods prevent binding and maintain precise pallet alignment over the long travel.
Dual-Side CNC Loader
Feeds bar stock into a lathe while a rear-mounted DMSE sensor flag triggers the chuck clamp, capitalizing on the cylinder's equal 1154 N force at 0.7 MPa.
Is the Airtac SED Double Rod Cylinder SED50X750S the Right Cylinder?
When sizing this 50mm bore, note the 825 N both-way output at 0.5 MPa. If your application requires less force, stepping down to the 40mm bore yields 528 N both ways. For heavier demands, the 63mm bore provides 1402 N at the same pressure. The twin-rod design is specifically chosen over a single-rod SE when you need superior anti-rotation stability, dual-side load guidance, or a rear rod end to mount a secondary cam or sensor flag.
For a direct ISO 15552 replacement, match the 50mm bore, 750mm stroke, PT1/4 port, and -S magnet. Because the stroke is 750mm, external guide rails are strongly recommended to prevent rod sagging and side-load wear on the end covers. Remember, a standard SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end. For fail-safe holding, specify a 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 SED50X750S FAQ
Because the double-rod design subtracts the rod area on 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.
The SED50X750S provides superior load guidance and anti-rotation properties. A rod exits both ends, allowing you to mount rear-side tooling or sensors while maintaining identical push and pull forces across its 750mm travel.
