Airtac SED Double Rod Cylinder SED50X30
The AirTAC SED Double Rod Cylinder SED50X30 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 30mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X30
The AirTAC SED50X30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 30 mm stroke. Because a 20 mm rod exits both ends, the effective piston area is identical on extend and retract, yielding a uniform 825 N of force in either direction at 0.5 MPa. The extruded aluminum barrel integrates sensor grooves, though this specific SKU ships without a magnet.
This through-rod design provides superior anti-rotation guidance and allows the rear rod end to drive a secondary mechanism or mount a cam. Field-adjustable air cushions at both ends decelerate the load near stroke end, while the PT1/4 ports and M16x1.5 rod threads handle standard pneumatic connections.

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 SED50X30 Is Used
Glass Edge Grinder
Drives a twin-sided grinding head with 825 N of equal force, using the through-rod to maintain strict parallelism during the 30 mm clamping stroke.
PCB Stamping Press
Provides anti-rotation stability for high-speed component stamping, operating at up to 800 mm/s while the rear rod end actuates a limit flag.
Pallet Diverter Gate
Uses the dual-rod structure to push heavy pallets evenly on both extend and retract strokes without inducing cylinder binding.
Is the Airtac SED Double Rod Cylinder SED50X30 the Right Cylinder?
With 825 N of equal bidirectional force at 0.5 MPa, this 50 mm bore fits applications needing balanced push and pull within a tight 30 mm stroke. If you need less force, the 40 mm bore provides 528 N both ways; stepping up to the 63 mm bore yields 1402 N. Choose this double-rod SED over a single-rod SE when your mechanism requires twin load guidance, rear-rod tooling, or strict anti-rotation control. For an ISO 15552 direct replacement, match the 50 mm bore, 30 mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED will drift on air loss; for fail-safe holding, use a BSED rod lock or external check valve.
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 SED50X30 FAQ
The SED50X30 provides equal force in both directions due to the double rod: 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The SED50X30 twin-rod design prevents load rotation, allows the rear rod to drive a secondary cam or sensor flag, and ensures the push and pull forces are identical, which is critical for precision transfer mechanisms.
