Airtac SDAD Double Rod Slim Cylinder SDAD40X15SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X15SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 15mm 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 SDAD40X15SB
The AirTAC SDAD40X15SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies each chamber equally, the annular area remains constant, delivering 527.8 N of force at 0.5 MPa in both extend and retract directions. This symmetric output is ideal for balanced tooling.
This specific configuration includes a built-in magnet for position sensing alongside male M14x1.5 rod threads on both ends. The short 15 mm stroke minimizes overall axial footprint, while the fixed NBR bumpers absorb end-of-stroke impacts within the 30-500 mm/s operating speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD40X15SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X15SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 15 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SDAD40X15SB Is Used
Gripper Jaw Actuation
Drives opposing gripper fingers where the male M14x1.5 threads mount custom jaws, utilizing the 527.8 N bidirectional force for secure part clamping.
Symmetric Transfer Pusher
Pushes a workpiece forward and retracts with identical 527.8 N force, preventing twisting on the guide rails during high-speed transfer operations.
Dual-End Pick & Place
Mounts a vacuum cup on one rod end and a sensor dog on the opposite end, leveraging the anti-rotation through-rod for precise 15 mm placement.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X15SB the Right Cylinder?
When sizing this unit, compare its 527.8 N output at 0.5 MPa against neighboring bores: the SDAD32 provides 345.6 N, whereas the SDAD50 offers 824.7 N. The through-rod geometry prevents twisting and permits mounting a tool on one end with a dog on the opposite side.
Remember that a standard cylinder drifts when air pressure is lost or the valve centers, as the NBR bumper only decelerates the stroke end rather than locking the piston. For load-holding requirements, integrate an external rod lock or pilot-operated check valve. This model is confirmed with a 40 mm bore, 15 mm stroke, PT1/8 port, male M14x1.5 rods, and a magnetic piston for reed or electronic switches.
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 SDAD40X15SB FAQ
The push and pull forces are equal at 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the double-rod design features male M14x1.5 threads on both ends, allowing you to drive a tool on one side while mounting a switch dog on the other. The through-rod also resists rotational twist.
