Airtac SED Double Rod Cylinder SED100X50S
The AirTAC Airtac SED Double Rod Cylinder SED100X50S is a genuine double-acting ISO 15552 double-rod cylinder: a Ø25mm piston rod exits BOTH ends of the Ø100mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 50mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X50S
The AirTAC SED100X50S is a double-acting, double-rod profile cylinder delivering 3681 N of force in both directions at 0.5 MPa. Because a 25 mm rod exits both ends of the 100 mm piston, the effective annulus area is identical on extend and retract, ensuring perfectly balanced output. It features an extruded aluminum barrel conforming to ISO 15552 dimensional standards.
Equipped with a standard magnet (-S), this unit supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The PT1/2 port and field-adjustable air cushions at both ends manage kinetic energy, while the rear rod end provides a rigid platform for mounting secondary tooling or cam flags.
Airtac SED Double Rod Cylinder SED100X50S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 50 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 36 mm |
| Max stroke | Up to 1500 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 SED100X50S Is Used
Servo Press Platen
Drives a CNC press platen requiring 3681 N of equal force both ways, using the twin rods to prevent torsional deflection during high-precision metal stamping.
PCB Panel Lifter
Lifts heavy fiberglass panels in an SMT line. The rear rod simultaneously actuates a cam flag to trigger a DMSE electronic sensor for precise height tracking.
Pallet Divert Arm
Actuates a diverting gate on a 50 mm stroke. The symmetrical 5153 N output at 0.7 MPa ensures snappy retraction and extension without speed mismatch.
Is the Airtac SED Double Rod Cylinder SED100X50S the Right Cylinder?
Select this 100 mm bore when an application requires 3681 N of symmetrical thrust at 0.5 MPa. If your load is lighter, the 80 mm bore provides 2268 N both ways; for heavier demands, the 125 mm bore yields 5734 N. The SED100X50S excels over a single-rod SE by guiding the load against rotation and allowing rear-rod mechanics. Note that a plain SED drifts on air loss—the cushion only decelerates near stroke end, so use a BSED or external lock for fail-safe holding. Ensure your replacement matches the 100 mm bore, 50 mm stroke, PT1/2 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SED100X50S FAQ
Because the 25 mm rod occupies both sides of the piston, force is equal in both directions: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin-rod design offers superior anti-rotation guidance and allows the rear rod to drive a secondary mechanism or sensor flag. It is dimensionally interchangeable per ISO 15552 but omits FB, CA, CB, and CR mounts.
