Airtac SED Double Rod Cylinder SED100X450S
The AirTAC Airtac SED Double Rod Cylinder SED100X450S 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 450mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X450S
The AirTAC SED100X450S is a double-acting, double-rod profile cylinder built to ISO 15552 dimensional standards. Because a 25mm rod exits both end covers, the annular piston area is identical on extend and retract. This yields equal force in both directions, generating 3681 N at 0.5 MPa and 5153 N at 0.7 MPa.
Equipped with a standard magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel omits external tie rods, while the field-adjustable air cushion at both ends decelerates the 450mm travel. The rear rod protrusion allows mounting a cam or secondary mechanism, providing superior anti-rotation guidance for heavy loads.

| Stroke | 450 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 SED100X450S Is Used
Pallet Transfer Diverters
Drives heavy pallet diverters using 5153 N of equal both-way force at 0.7 MPa, ensuring consistent push and pull speeds across the 450mm stroke.
Twin-Spindle Lifting Frames
Lifts heavy machining fixtures with anti-rotation stability. The rear rod end mounts a cam to trigger limit flags without external sensors.
Heavy-Duty Indexing Gates
Actuates large automated safety gates. The double-rod design balances the load across both end covers, preventing binding over the long travel.
Is the Airtac SED Double Rod Cylinder SED100X450S the Right Cylinder?
Selecting this 100mm bore provides 3681 N of bidirectional force at 0.5 MPa. If your application requires less force, stepping down to the 80mm bore yields 2268 N. If you need more power, the 125mm bore provides 5734 N. Choose this double-rod SED over a single-rod SE when you need to drive twin loads, prevent rotation, or mount rear tooling.
With a 450mm stroke, the 25mm rod and M20x1.5 thread require external load guiding to prevent side-load damage. This cylinder uses a PT1/2 port and accepts Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts (omitting FB/CA/CB/CR). Note that the adjustable air cushion only decelerates near stroke end; it does not hold position on air loss. For fail-safe holding, use a BSED double-rod rod lock.
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 SED100X450S FAQ
The SED100X450S generates equal force in both directions because the 25mm rod occupies both sides of the piston. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and reaches a maximum of 751 kgf at 1.0 MPa.
A double-rod cylinder provides identical extend and retract forces, which is critical for balanced automation. It also offers better load guidance against rotation and provides a rear rod end for mounting secondary cams, flags, or tooling.
