Airtac SED Double Rod Cylinder SED50X210S
The AirTAC SED Double Rod Cylinder SED50X210S 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 210mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X210S
The AirTAC SED50X210S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 20mm rod exits both ends, the annulus area is identical on extend and retract. This means you get exactly 825 N of force in both directions at 0.5 MPa, eliminating speed and thrust mismatch.
The extruded aluminum barrel has no external tie rods, and the included -S magnet enables position sensing with CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends absorb kinetic energy near stroke end, while the rear rod 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 SED50X210S Is Used
PCB Edge Guiding
Uses the 825N equal both-way force to center and clamp delicate printed circuit boards during conveyor transfer, relying on twin rods to prevent grip yaw.
Dual-Side Pick & Place
Drives a front gripper to pick parts while the rear rod simultaneously actuates a diverter cam, maximizing the 210mm stroke efficiency without adding valves.
Indexing Hopper Gate
Actuates a sliding discharge gate on a packaging hopper, using the -S magnet and DMSE sensor to confirm gate position under varying material loads.
Is the Airtac SED Double Rod Cylinder SED50X210S the Right Cylinder?
Choose this 50mm bore if your application requires 825 N of equal bidirectional force at 0.5 MPa. If you need less thrust, step down to the 40mm bore providing 528 N both ways; if moving heavier payloads, step up to the 63mm bore yielding 1402 N. The twin rods provide superior anti-rotation stability compared to a single-rod SE cylinder, making it ideal for guiding loads over its 210mm stroke.
Because this stroke exceeds 300mm? No, at 210mm side loads are moderate, but external guides are still recommended for heavy off-center loads. Note that the adjustable cushion decelerates the piston but does not lock it; a plain SED will drift on air loss, so specify a BSED or external lock for fail-safe holding. When replacing an ISO 15552 unit, match the 50mm bore, 210mm stroke, PT1/4 port, and 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 SED50X210S FAQ
The SED50X210S provides equal force in both extend and retract directions due to its double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and reaches a maximum of 168 kgf at 1.0 MPa.
A double-rod cylinder provides identical force and speed in both directions because the rod occupies both sides of the piston. It also offers better load guidance and anti-rotation resistance, and the rear rod can be used to mount sensors or drive a secondary mechanism.
