Airtac SED Double Rod Cylinder SED125X130
The AirTAC Airtac SED Double Rod Cylinder SED125X130 is a genuine double-acting ISO 15552 double-rod cylinder: a Ø32mm piston rod exits BOTH ends of the Ø125mm bore, giving equal force and speed in both directions and letting you mount tooling or a sensor flag on the back rod. Stroke 130mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED125X130
The AirTAC SED125X130 is a double-acting, double-rod profile cylinder built to the ISO 15552 dimension standard. Because a 32 mm rod exits both ends of the 125 mm piston, the effective annulus area is symmetrical. This yields an identical driving force in extend and retract—5734 N at 0.5 MPa and 8028 N at 0.7 MPa both ways.
This unit features an extruded aluminum barrel without external tie rods, operating at 30-500 mm/s. It includes field-adjustable air cushioning at both ends to decelerate heavy loads near stroke end. This specific SKU lacks a magnet, so it does not support CMSE or DMSE position sensing.
Airtac SED Double Rod Cylinder SED125X130 Technical Specifications
| Model | Airtac SED Double Rod Cylinder SED125X130 |
|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø125 mm |
| Stroke | 130 mm |
| Configuration | Double rod, double acting |
| Port size | PT1/2 |
| Rod thread | M27×2 |
| 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 – 500 mm/s |
| Cushion | Adjustable, 40 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 (Ø125mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 5734 N |
| 0.7 MPa | 8027 N |
| Max (@1.0 MPa) | 1169 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 SED125X130 Is Used
Servo Press Sub-Assembly
Drives an 8028 N pressing head while the rear rod simultaneously triggers a mechanical limit flag, ensuring perfectly synchronized downstroke and upstroke forces.
Multi-Spot Welding Station
Applies 5734 N of equal clamping pressure on both extend and retract strokes to hold sheet metal panels flat against a fixture during robotic spot welding.
Heavy Mill Roll Ejector
Ejects 125 mm steel mill rolls from a lathe using twin 32 mm rods that resist torsional twisting and maintain precise alignment under high dynamic stress.
Is the Airtac SED Double Rod Cylinder SED125X130 the Right Cylinder?
At 0.5 MPa, this 125 mm bore generates 5734 N both directions. Stepping down to the 100 mm bore drops output to 3681 N, while no larger bore exists in this series, making this the maximum force option. Choose this double-rod design over a single-rod SE when you need to prevent load rotation or drive a secondary mechanism from the rear rod.
For replacement, match the 125 mm bore, 130 mm stroke, PT1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). A plain SED does not hold position on air loss; for fail-safe holding, use a BSED double-rod rod lock. Since stroke is under 300 mm, external side-load guides are less critical but still recommended for heavy 1169 kgf loads.
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 SED125X130 FAQ
The SED125X130 provides equal force in both directions due to the double-rod design. It outputs 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and reaches a maximum of 1169 kgf at 1.0 MPa.
A double-rod cylinder provides identical extend and retract forces, better load stability against rotation, and a rear rod end for mounting secondary cams or tooling. It is dimensionally interchangeable with other ISO 15552 double-rod profile cylinders.
