Airtac SED Double Rod Cylinder SED50X300S
The AirTAC SED Double Rod Cylinder SED50X300S 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 300mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X300S
The AirTAC SED50X300S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 300mm stroke. Because a rod exits both end covers, the annular piston area is symmetrical, generating 825 N of force in both extend and retract directions at 0.5 MPa. The extruded aluminum barrel contains integrated sensor grooves, and this -S variant includes a magnet for CMSE reed or DMSE electronic sensors.
Equipped with field-adjustable air cushioning at both ends (30mm cushion length), it safely decelerates the load near stroke extremes. The twin M16x1.5 rods provide high torsional resistance, making it excellent for driving separate mechanisms from the rear rod end while maintaining precise alignment.
Airtac SED Double Rod Cylinder SED50X300S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED50X300S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 300 mm |
| Configuration | Double rod, double acting |
| 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 |
| Max stroke | Up to 1200 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 SED50X300S Is Used
Web Guiding
Provides 825 N of equal both-way force to steer and tension paper or film webs, using the twin rods to resist torsional twisting during high-speed shifts.
Dual-Side Machining
Drives a rear-rod cam to index a secondary spindle while the front rod positions the part, leveraging the 300mm travel for extended reach.
Transfer Pusher
Pushes pallets between parallel conveyors with 1154 N at 0.7 MPa, relying on the double-rod design to prevent binding over the long 300mm stroke.
Is the Airtac SED Double Rod Cylinder SED50X300S the Right Cylinder?
Select this 50mm bore when your mechanism needs 825 N both ways at 0.5 MPa; step down to the 40mm bore for 528 N, or up to the 63mm bore for 1402 N if your payload requires more thrust. Choose this double-rod SED over a single-rod SE when your application demands anti-rotation stability or requires mounting a rear cam, sensor flag, or secondary tooling. At 300mm stroke, the extended rod length increases side-load leverage—ensure external guides support the load to prevent binding. For a true ISO 15552 replacement, match the 50mm bore, 300mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that air cushions only decelerate near stroke end; a plain SED drifts on air loss, so specify a BSED or external rod lock for fail-safe position 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 SED50X300S FAQ
Because the double-rod design has equal piston areas on both sides, it generates 825 N at 0.5 MPa and 1154 N at 0.7 MPa in both directions, with a maximum of 168 kgf at 1.0 MPa.
Yes, the SED50X300S is dimensionally interchangeable per ISO 15552. Just match the 50mm bore, 300mm stroke, PT1/4 port, and your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2), while ensuring you leave clearance for the rear rod.
