Airtac SED Double Rod Cylinder SED50X220
The AirTAC SED Double Rod Cylinder SED50X220 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 220mm, PT1/4 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED50X220
The AirTAC SED50X220 is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding equal force both ways: 825 N at 0.5 MPa and 1154 N at 0.7 MPa. The extruded aluminum barrel has no external tie rods, and adjustable air cushioning at both ends decelerates the 220 mm stroke.
This SKU has no magnet (-S omitted), so it cannot host CMSE or DMSE position sensors. The rear rod end protrudes from the back cover, providing a second mounting point for a cam or mechanical flag. With a 20 mm rod and M16x1.5 thread, it handles dual-side guidance tasks while maintaining a 30-800 mm/s speed range.

| 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 SED50X220 Is Used
Web Edge Guiding
Drives an alignment roller for film or foil processing. The 825 N bidirectional force ensures precise tracking, while the rear rod actuates a mechanical flag for a hard limit.
Dual-Station Transfer
Indexes parts between two machining stations simultaneously. The twin rods prevent rotation during the 220 mm traverse, maintaining part orientation without external guides.
Gripper Synchronization
Actuates opposing gripper jaws on an assembly fixture. Equal force both ways ensures balanced clamping of 1154 N at 0.7 MPa, preventing workpiece deformation.
Is the Airtac SED Double Rod Cylinder SED50X220 the Right Cylinder?
Select this 50 mm bore when you need 825 N of bidirectional force at 0.5 MPa. If your load is lighter, the 40 mm bore provides 528 N both ways; if you need more push, the 63 mm bore offers 1402 N. The twin-rod design resists rotation better than a single-rod SE cylinder and allows rear-rod tooling. Since this is a 220 mm stroke, external guides are recommended to manage side loads and prevent binding over the longer travel.
For ISO 15552 replacements, match the 50 mm bore, 220 mm stroke, PT1/4 port, and preferred mounting (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that a plain SED does not hold position on air loss—the piston drifts. The cushions only decelerate near stroke end. For fail-safe holding, use a BSED double-rod rod lock or an external pilot-operated 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 SED50X220 FAQ
The SED50X220 provides equal force in both directions due to the double-rod design. It outputs 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and reaches a maximum of 168 kgf at 1.0 MPa.
Yes. The SED50X220 is dimensionally interchangeable per ISO 15552 / VDMA 24562. Match the 50 mm bore, 220 mm stroke, PT1/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, TCM2) for a direct replacement.
