Airtac SED Double Rod Cylinder SED50X200S
The AirTAC SED Double Rod Cylinder SED50X200S 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 200mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X200S
The AirTAC SED50X200S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Featuring a 50 mm bore and 200 mm stroke, it uses an extruded aluminum barrel without external tie rods. Because a 20 mm rod exits both end covers, the effective piston area is identical on extend and retract. This yields equal force in both directions, generating 825 N at 0.5 MPa and 1154 N at 0.7 MPa.
Equipped with a standard magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for tracking both stroke ends. The rear rod extension can mount a secondary cam or limit flag to trigger external mechanisms, while simultaneously guiding the load against torsional rotation. Adjustable air cushions at both ends absorb impact, and the PT1/4 ports ensure straightforward pneumatic integration.

| 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 |

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 SED50X200S Is Used
Web Guide Mechanism
Provides 825 N of equal bidirectional force at 0.5 MPa to steer and tension continuous material webs without rotational deflection.
Dual-Side Divert Gate
Uses the through-rod design to actuate sorting flaps on both sides of a conveyor simultaneously, ensuring synchronized package handling.
Pick-and-Place Transfer
Leverages the rear rod end to mount a secondary cam while driving a 200 mm stroke transfer arm, maintaining precise parallel movement.
Is the Airtac SED Double Rod Cylinder SED50X200S the Right Cylinder?
When sizing this 50 mm bore, compare its 825 N both-way output at 0.5 MPa against adjacent options. Stepping down to the 40 mm bore yields 528 N, while stepping up to the 63 mm bore provides 1402 N. Choose this double-rod SED over a single-rod SE when your application demands equal push-pull forces, anti-rotation stability, or a rear-rod output for secondary tooling. For ISO 15552 direct replacement, match the 50 mm bore, 200 mm stroke, PT1/4 port, and -S magnet, selecting from Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
Remember that a standard SED does not hold position on air loss; the piston drifts. The adjustable cushion only decelerates near stroke end and is not a lock. For fail-safe holding, use a BSED double-rod lock cylinder or an external pilot-operated check valve. At 200 mm stroke, side loads are minimal, but always guide the load externally to prevent binding.
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 SED50X200S FAQ
Because the double-rod design yields equal effective area both ways, the SED50X200S generates 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa in both extend and retract directions.
The twin rods provide equal push-pull force, better anti-rotation guidance for the load, and a rear rod end that can drive a secondary mechanism or mount a sensor flag, which a single-rod SE cannot offer.
