Airtac SED Double Rod Cylinder SED100X650S
The AirTAC Airtac SED Double Rod Cylinder SED100X650S 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 650mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X650S
The AirTAC SED100X650S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 650mm stroke. Because a rod exits both end covers, the effective piston area is identical on extend and retract, yielding an equal drive force of 3681 N each way at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring clean integration and dimensional interchangeability per ISO 15552.
Equipped with a standard -S magnet, this unit supports CMSE reed and DMSE electronic sensors for precise end-position detection. The rear rod extension can mount a cam or secondary tooling flag, while field-adjustable air cushions at both ends decelerate the load near stroke ends without acting as a position lock.
Airtac SED Double Rod Cylinder SED100X650S Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 650 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 SED100X650S Is Used
Web Guide Mechanism
Delivers 5153 N of equal both-way force to steer heavy paper or film webs, using the rear rod for a cam-driven tensioning arm to prevent rotation.
Tandem Press Drive
Drives a dual-sided stamping or pressing station where the twin 25mm rods carry opposing tooling, ensuring perfectly balanced 3681 N clamping at 0.5 MPa.
Pallet Transfer Pusher
Shifts heavy pallets using the front rod while the rear rod triggers a DMSE electronic sensor flag, synchronizing the 650mm transfer cycle.
Is the Airtac SED Double Rod Cylinder SED100X650S the Right Cylinder?
Selecting this 100mm bore provides a substantial 5153 N both-way force at 0.7 MPa. If your application requires less thrust, stepping down to the 80mm bore yields 2268 N at 0.5 MPa, while moving up to the largest 125mm bore provides 5734 N at 0.5 MPa. Choose this double-rod SED over a single-rod SE when you need superior anti-rotation guidance, dual-side load driving, or rear-mounted sensing.
For a drop-in ISO 15552 replacement, match the 100mm bore, 650mm stroke, PT1/2 port, and preferred mounting from the Basic, FA, LB, TC, FTC, TCM1, or TCM2 set (omitting FB, CA, CB, CR). At 650mm stroke, the extended twin rods demand external load guides to prevent side-load damage. Note that a plain SED will drift on air loss; for fail-safe holding, use a BSED rod lock or 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 SED100X650S FAQ
The SED100X650S provides equal force in both directions due to the double-rod design: 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and a maximum of 751 kgf at 1.0 MPa.
The twin rods exiting both ends offer better anti-rotation guidance and allow the rear rod to drive a secondary mechanism or sensor flag. It uses the same ISO 15552 mounting interface but requires rear-rod clearance.
