Airtac SED Double Rod Cylinder SED125X110
The AirTAC Airtac SED Double Rod Cylinder SED125X110 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 110mm, PT1/2 ports, adjustable cushioning.

About the Airtac SED Double Rod Cylinder SED125X110
The AirTAC SED125X110 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 125mm bore and 110mm stroke. Because a 32mm rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 5734 N of force in both directions at 0.5 MPa. The extruded aluminum barrel contains no external tie rods, ensuring a clean profile that drops in dimensionally for any ISO 15552 footprint.
This SKU lacks the -S magnet option, meaning it has no onboard position sensing out of the box. The rear rod extension is highly useful for mounting a mechanical cam or driving a secondary mechanism, while providing superior anti-rotation guidance for heavy loads. Field-adjustable air cushions at both ends provide tailored deceleration near stroke ends.
Airtac SED Double Rod Cylinder SED125X110 Technical Specifications

|---|---|
| Series | SED ISO 15552 double-rod cylinder |
| Bore size | Ø125 mm |
| Stroke | 110 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 SED125X110 Is Used
Heavy Stamping Press Feeders
Provides 5734 N of equal both-way force to drive heavy material grippers in large stamping presses, using the rear rod to mount an external cam for synchronizing the mechanical feeder.
Large Panel Bending Machines
The twin 32mm rods guide the clamping beam against rotation during thick steel panel bending, ensuring perfectly parallel pressure across the 125mm bore's full 110mm stroke.
Dual-Side Shuttle Conveyors
Delivers 8028 N at 0.7 MPa to push and pull heavy pallet shuttles equally in both directions, leveraging the through-rod design to attach secondary linkage on the rear actuator end.
Is the Airtac SED Double Rod Cylinder SED125X110 the Right Cylinder?
When sizing this 125mm bore, note the 80mm option steps down to 2268 N at 0.5 MPa, while the 125mm itself provides 5734 N both ways at 0.5 MPa and 8028 N at 0.7 MPa. Choose this largest standard profile bore when a single-rod SE cylinder cannot provide the bidirectional stability or rear-rod tooling mounting required for heavy fabrication. To replace an existing ISO 15552 unit, match the 110mm stroke, PT1/2 port, and mounting choice from Basic, FA, LB, TC, FTC, TCM1, or TCM2. Remember that a plain SED does not hold position on air loss; for fail-safe holding, specify a BSED double-rod lock cylinder. At 110mm stroke, side loads are minimal, but external guides should still carry the primary load mass.
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 SED125X110 FAQ
The SED125X110 delivers an equal force in both extend and retract directions due to its double-rod design. It outputs 5734 N at 0.5 MPa, 8028 N at 0.7 MPa, and a maximum of 1169 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. You can drop it in for other double-rod profile cylinders by matching the 125mm bore, 110mm stroke, PT1/2 port, and selecting from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.
