Airtac SED Double Rod Cylinder SED50X375
The AirTAC SED Double Rod Cylinder SED50X375 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 375mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X375
The AirTAC SED50X375 is a double-acting, double-rod profile cylinder built to the ISO 15552 interface. Because a rod exits both ends, the annular piston area is symmetrical, yielding an equal 825 N of drive force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel integrates sensor grooves, though this specific SKU lacks the -S magnet option for position sensing.
Equipped with a 20 mm rod on each side and an M16x1.5 rod-end thread, it provides superior anti-rotation guidance for external loads. Field-adjustable air cushioning at both ends decelerates the motion near the 375 mm stroke limits, while the PT1/4 porting handles the pneumatic supply.

| 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 SED50X375 Is Used
Web Guiding Mechanism
Uses the 825 N both-way force to push and pull a paper film guide evenly, relying on the twin rods to prevent deflection across the 375 mm travel.
Dual-Side Transfer Gate
Drives a sliding gate between two packaging stations, utilizing the equal extend and retract speeds to maintain a consistent cycle time.
Rear-Rod Cam Actuation
Leverages the protruding rear rod to trigger a mechanical limit switch cam, operating a secondary assembly sequence in sync with the main motion.
Is the Airtac SED Double Rod Cylinder SED50X375 the Right Cylinder?
Choose this 50 mm bore if your mechanism requires 825 N of both-way force at 0.5 MPa. If you need less power, the 40 mm bore provides 528 N both ways; if your load demands more, step up to the 63 mm bore which outputs 1402 N both ways at 0.5 MPa. The twin-rod design is preferred over a single-rod SE cylinder when you need to mount a cam or secondary tooling on the rear rod, or when rotational stability is critical.
At a 375 mm stroke, the extended rod length increases the risk of side-load bucking, so external guide rails are recommended to prevent binding. Remember that a standard SED does not hold position on air loss—the piston will drift without pressure. For fail-safe holding, consider a BSED double-rod rod lock or an external pilot-operated check valve. To replace an existing ISO 15552 unit, match the 50 mm bore, 375 mm stroke, PT1/4 port, and your required mounting style from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 set.
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 SED50X375 FAQ
Because the double-rod design has equal piston area on both sides, it generates 825 N of force both ways at 0.5 MPa, 1154 N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
The SED50X375 provides equal force and speed in both directions, and the rear rod allows for mounting secondary tooling or a cam. It also offers better resistance to load rotation, though you must ensure rear-rod clearance for the 375 mm stroke.
