Airtac SDAD Double Rod Slim Cylinder SDAD25X45
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X45 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 45mm 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 SDAD25X45
The AirTAC SDAD25X45 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 is identical in each direction, giving exactly 206.2 N of force at 0.5 MPa on both extend and retract strokes. This symmetric output is perfect for balancing loads without favoring one travel direction.
A 10 mm piston rod protrudes from each end, actively resisting twist during motion while allowing you to mount a work tool on one side and a dog or fixture on the opposite side. The short body design saves axial mounting depth in tight machinery. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD25X45 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X45 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 45 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 SDAD25X45 Is Used
Gripper Synchronization
Drives opposing gripper jaws where the 206.2 N bidirectional force ensures perfectly balanced clamping pressure on delicate components.
Transfer Pusher
Pushes parts along a belt using the through-rod design to mount a dog on the rear end for mechanical tracking without twist.
Flap Folding
Folds carton flaps in tight spaces, leveraging the compact riveted body to fit within narrow packaging machine frames.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X45 the Right Cylinder?
When sizing this unit, compare its 206.2 N output at 0.5 MPa against neighboring bores: the SDAD20 provides 131.9 N, while the SDAD32 offers 345.6 N. This makes the 25 mm bore the optimal middle ground for medium-duty symmetric tasks. A safe working load is roughly 124 N, or a vertical lift of about 10.5 kg with a 2:1 safety margin.
This specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; choose the -S option if position sensing is required. The rod-end threads are female M5x0.8 on both ends, and the air port is M5x0.8. Remember that a standard cylinder drifts if air pressure is lost or the valve is centered, so add an external rod lock or pilot-operated check valve for load holding.
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 SDAD25X45 FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa in both directions.
Yes, the through-rod design allows you to attach a tool or dog on both ends while providing anti-rotation resistance. Note that this specific SKU has no magnet, so you cannot use magnetic switches for position sensing.
