Airtac SED Double Rod Cylinder SED50X500
The AirTAC SED Double Rod Cylinder SED50X500 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 500mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X500
The AirTAC SED50X500 is a double-acting, double-rod profile cylinder adhering to the ISO 15552 dimensional standard. Because a 20mm rod exits both end covers, the annular piston area is balanced, generating an equal 825N of thrust and pull force at 0.5 MPa. It uses a PT1/4 port and a 30mm adjustable air cushion at each end to manage kinetic energy.
This 500mm stroke configuration lacks the standard piston magnet, meaning it will not trigger CMSE or DMSE sensors without modification. The rear rod protrusion allows engineers to mount a cam or secondary tooling, while the twin-rod geometry inherently resists torsional load and provides superior anti-rotation guidance compared to a single-rod SE cylinder.
Airtac SED Double Rod Cylinder SED50X500 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 500 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 SED50X500 Is Used
Web Edge Guiding
Drives a 500mm correction carriage in film converting lines. The 825N both-way force keeps the tracking frame perfectly balanced, while the twin rods prevent binding across the long stroke.
Multi-Station Indexing
Shifts a machining pallet 500mm between stations. The rear rod supports a secondary cam plate for actuating downstream clamps, utilizing the equal push/pull force for consistent cycling.
Dual-Side Grippers
Actuates opposing 500mm gripper arms in packaging machinery. The symmetrical 1154N force at 0.7 MPa ensures both jaws clamp with identical pressure, guided by the extruded ISO 15552 profile.
Is the Airtac SED Double Rod Cylinder SED50X500 the Right Cylinder?
At 0.5 MPa, this 50mm bore yields 825N both ways; stepping down to the 40mm bore drops output to 528N, while moving up to the 63mm bore increases it to 1402N. Choose the SED50X500 when your mechanism requires equal push/pull forces, rear-rod tooling, or strict anti-rotation control. As a direct ISO 15552 replacement, verify your port (PT1/4), mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2), and 500mm stroke clearance.
Because this 500mm stroke creates a long overhang, external guide rails are recommended to prevent side-load damage to the seals. Note that this non-magnetized SKU cannot hold position on air loss—the piston drifts, and the cushions only decelerate near stroke end, so specify a BSED or external rod lock for fail-safe 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 SED50X500 FAQ
Because the double-rod design subtracts the 20mm rod area from both piston sides, output is identical in both directions: 825N at 0.5 MPa, 1154N at 0.7 MPa, and a maximum of 168 kgf at 1.0 MPa.
Yes, the SED50X500 matches ISO 15552 / VDMA 24562 mounting dimensions and uses the standard SE mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Just ensure you leave rear-rod clearance, as the overall length is longer than a single-rod cylinder.
