Airtac SDAD Double Rod Slim Cylinder SDAD25X120
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X120 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 120mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.

About the Airtac SDAD Double Rod Slim Cylinder SDAD25X120
The AirTAC SDAD25X120 is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area remains identical in each direction, giving you exactly 206.2 N of push and pull force at 0.5 MPa. This symmetry prevents twisting moments and ensures stable motion across the full 120 mm travel.
Equipped with a 10 mm piston rod and an M5x0.8 air port, this unit operates at speeds between 30 and 500 mm/s. End-of-stroke energy is managed strictly by a fixed NBR bumper, which decelerates the piston near the end caps rather than acting as an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot directly host magnetic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD25X120 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X120 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 120 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
| Max standard stroke | Up to 120 mm |
Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
Theoretical Output Force (Ø25mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Where the Airtac SDAD Double Rod Slim Cylinder SDAD25X120 Is Used
Gripper Jaw Actuation
Drives opposing gripper fingers where equal 206.2 N clamping and release forces are required to prevent part deformation during automated handling.
Pallet Diverting Gate
Uses the dual-end through-rod to push a diverting flap on one side while mounting a mechanical stop on the other, maintaining alignment without twisting over 120 mm.
Film Feed Tensioning
Applies consistent 206.2 N bidirectional tension on packaging film webs, ensuring the material stays taut during the extend and retract cycles.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X120 the Right Cylinder?
When sizing this model, compare its 206.2 N output at 0.5 MPa against adjacent bores: the SDAD20 provides 131.9 N, while the SDAD32 offers 345.6 N. Based on the 206.2 N figure, a safe working load is roughly 124 N (about 60 percent capacity), translating to a vertical lift capability of approximately 10.5 kg with a 2:1 safety margin. Choose the 25 mm bore when your symmetric load falls squarely in that range.
The through-rod design inherently resists rotation, allowing you to mount a tool on one end and a dog on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed NBR bumper only decelerates the stroke end and will not hold the load. For secure positioning, integrate an external rod lock or pilot-operated check valve. This configuration features a 120 mm stroke, female M5x0.8 rod-end threads, and no magnet.
Quick checklist
- ✓ Need equal force both directions?
- ✓ Anti-rotation / dual-end mounting?
- ✓ Space for a rod that exits both ends
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Leave clearance for the rod exiting both ends.
- check Avoid side load on either rod end.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAD Double Rod Slim Cylinder SDAD25X120 FAQ
The double-rod design provides equal force in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The theoretical maximum is 42 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet. You must select the -S variant to use AirTAC reed or electronic switches in the body sensor grooves for position detection.
