Airtac SED Double Rod Cylinder SED50X75S
The AirTAC SED Double Rod Cylinder SED50X75S 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 75mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X75S
The AirTAC SED50X75S is a double-acting, double-rod ISO 15552 profile cylinder. Because a 20mm rod exits both ends, the effective piston area is identical on extend and retract, yielding an equal 825N of force each way at 0.5 MPa. The extruded aluminum barrel includes sensor grooves, and the -S magnet enables position tracking via DMSE electronic or CMSE reed switches.
This through-rod design provides superior anti-rotation guidance for external loads and allows a rear cam or limit flag to trigger secondary sensors. Field-adjustable air cushions at both ends absorb 30mm of impact near stroke end, protecting your tooling. The standard PT1/4 ports and M16x1.5 rod threads ensure straightforward integration.

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 SED50X75S Is Used
Web Guide Mechanisms
Provides 825N of equal both-way force to steer material webs, using the rear rod end for a tracking cam while preventing load rotation.
Dual-Side Press Tooling
Drives opposing forming heads simultaneously, leveraging the 1154N output at 0.7 MPa and the anti-rotation stability of the twin 20mm rods.
Pneumatic Diverter Arms
Actuates sorting gates on packaging lines where the 75mm stroke and symmetrical extend/retract speeds ensure consistent product routing.
Is the Airtac SED Double Rod Cylinder SED50X75S the Right Cylinder?
Stepping up to the 63mm bore raises both-way output to 1402N at 0.5 MPa, while dropping to the 40mm bore reduces it to 528N. Choose this 50mm double-rod SED over a single-rod SE when your application requires symmetrical force, dual-side tooling, or rear-rod actuation. For direct replacements, match the 50mm bore, 75mm stroke, PT1/4 ports, and -S magnet exactly. Note that the air cushion decelerates the load but does not hold position on air loss; for fail-safe locking, consider a BSED series 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 SED50X75S FAQ
Because the double-rod design subtracts rod area from both sides, force is equal in both directions: 825N at 0.5 MPa, 1154N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The twin rods provide better anti-rotation guidance for the load, allow mounting a cam or sensor flag on the rear rod, and deliver identical extend and retract forces for symmetrical machine movements.
