Airtac SED Double Rod Cylinder SED50X275S
The AirTAC SED Double Rod Cylinder SED50X275S 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 275mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X275S
The AirTAC SED50X275S is a double-acting, double-rod ISO 15552 profile cylinder with a 50 mm bore and 275 mm stroke. Because a Ø20 mm rod exits both end covers, the effective piston area is identical on extend and retract, yielding exactly 825 N of force each way at 0.5 MPa. The extruded aluminum barrel includes sensor grooves, and the included -S magnet enables position tracking with CMSE reed or DMSE electronic sensors.
Field-adjustable air cushions at both ends provide 30 mm of deceleration to absorb kinetic energy near stroke ends. The rear rod extension can drive a secondary mechanism or support a sensor flag, while the twin rods offer superior resistance to twist compared to a single-rod SE cylinder.

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 SED50X275S Is Used
Web Guiding in Slitter-Rewinders
Uses the 825 N equal both-way force to steer material evenly, while the rear rod mounts a cam to actuate a mechanical tensioner.
Shuttle Transfer Gates
Moves pallets between conveyors with identical push and pull speeds, leveraging the twin rods to prevent binding across the 275 mm stroke.
Dual-Side Component Pressing
Compresses assemblies from two directions simultaneously, using the -S magnet with DMSE sensors to verify mid-stroke positioning.
Is the Airtac SED Double Rod Cylinder SED50X275S the Right Cylinder?
Select this 50 mm bore when an application demands 825 N of equal bidirectional force at 0.5 MPa (1154 N at 0.7 MPa). If you need less force, the 40 mm bore provides 528 N both ways; if you need more, stepping up to the 63 mm bore yields 1402 N at 0.5 MPa. The twin-rod architecture is preferred over a single-rod SE when you need to drive a load from both ends, mount a rear cam, or prevent the load from rotating.
For a direct replacement, match the 50 mm bore, 275 mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that FB, CA, CB, and CR mounts are omitted from this series. At 275 mm stroke, the extended rod length requires checking rear clearance, and you should ensure external guides support any heavy lateral loads, as the twin rods handle anti-rotation but do not support excessive side loads. This cylinder is double-acting and will drift on air loss; use an external rod lock or a BSED series cylinder for fail-safe holding.
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 SED50X275S FAQ
The force is equal in both directions because of the double-rod design. It generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
No. The SED50X275S is double-acting and will drift if air pressure is lost. The adjustable air cushion only decelerates the load near the stroke end; it does not lock position. For fail-safe holding, consider an AirTAC BSED double-rod lock cylinder or an external pilot-operated check valve.
