Airtac SED Double Rod Cylinder SED50X750
The AirTAC SED Double Rod Cylinder SED50X750 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 SED50X750
The AirTAC SED50X750 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 on both sides, generating an equal 825 N of thrust and pull at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration and strict ISO 15552 dimensional interchangeability.
This specific SKU lacks the -S magnet option, meaning it cannot host CMSE reed or DMSE electronic sensors directly in the barrel grooves. You can use the protruding rear rod end to mount a mechanical cam or external flag for physical limit switching. Field-adjustable air cushions at both ends provide 30mm of deceleration to protect your tooling at stroke extremes.

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 750 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 SED50X750 Is Used
Package Sorter Diverter
Drives a dual-sided diverter arm on a packaging conveyor, utilizing the equal 825N both-way force to push boxes consistently in either direction without stroke asymmetry.
Web Guide Tensioning
Applies uniform tension to a moving web material in a printing press, using the twin rods to prevent binding and maintain precise tracking over the 750mm travel.
Press Feed Transfer
Shuttles metal blanks into a stamping press, using the rear rod end to mount an external mechanical flag that triggers a physical limit switch for sequencing.
Is the Airtac SED Double Rod Cylinder SED50X750 the Right Cylinder?
Selecting this 50mm bore provides 825 N both ways at 0.5 MPa, sitting between the 40mm bore (528 N) and the 63mm bore (1402 N). Choose the double-rod SED over a single-rod SE when your application demands superior anti-rotation guidance, simultaneous dual-side actuation, or a rear rod to drive a secondary mechanism. Remember that a standard SED does not hold position on air loss; the piston drifts, and the adjustable cushion only decelerates near stroke end, it does not lock. For fail-safe holding, consider a BSED double-rod lock cylinder.
At 750mm of stroke, the extended rod length requires careful alignment to prevent side-loading damage. Always support the load with external guides rather than relying solely on the piston rod. When replacing an existing ISO 15552 cylinder, match the 50mm bore, 750mm stroke, PT1/4 port, and your required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SED50X750 FAQ
Because the double-rod design subtracts the 20mm rod area from both sides of the piston, the force is identical 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.
This specific SKU does not include the -S magnet option, so it cannot host CMSE or DMSE sensors in the barrel grooves. However, the rear rod protruding from the back cover is ideal for mounting an external cam or physical limit flag.
