Airtac SED Double Rod Cylinder SED100X135S
The AirTAC Airtac SED Double Rod Cylinder SED100X135S 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 135mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED100X135S
The AirTAC SED100X135S is a double-acting, double-rod profile cylinder built to the ISO 15552 dimensional interface. Because a 25mm rod occupies both sides of the piston, the annulus area is identical in both directions. This means you get exactly 3681 N of output force at 0.5 MPa on extend and retract alike.
Equipped with a magnet (-S), it supports CMSE reed and DMSE electronic sensors for end-of-stroke detection. The extruded aluminum barrel lacks external tie rods, and the rear rod extension is ideal for mounting a cam, limit flag, or driving a secondary mechanism in parallel.
Airtac SED Double Rod Cylinder SED100X135S Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED100X135S |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 135 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 SED100X135S Is Used
Servo Press Platen
Drives a 5153 N stamping platen at 0.7 MPa where the rear rod simultaneously pushes a part ejector, keeping force perfectly balanced.
Pallet Transfer Gate
Shifts heavy pallets using equal 3681 N force in both directions, utilizing the twin rods to prevent platen twist during heavy lateral shifts.
Dual-Side Clamping Jig
Clamps large automotive castings from both ends simultaneously, using the through-rod design to maintain precise parallel alignment.
Is the Airtac SED Double Rod Cylinder SED100X135S the Right Cylinder?
Stepping down to the 80mm bore yields 2268 N at 0.5 MPa, while stepping up to the 125mm bore provides 5734 N both ways. Choose this 100mm option when your application demands substantial equal force and twin-rod anti-rotation stability. It uses a PT1/2 port and a 36mm adjustable air cushion at both ends to tame kinetic energy near stroke end.
A plain SED does not hold position upon air loss; the piston will drift. For fail-safe holding, consider an AirTAC BSED double-rod lock or an external pilot-operated check valve. Since the stroke is 135mm, ensure external guides support any heavy lateral loads to prevent binding against the M20x1.5 rod threads.
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 SED100X135S FAQ
Because the double-rod design has equal piston area on both sides, output force is identical 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.
Yes. The SED100X135S matches ISO 15552 / VDMA 24562 mounting dimensions. Just verify your mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2), ensure you have rear-rod clearance, and select PT or G ports.
