Airtac SDAD Double Rod Slim Cylinder SDAD40X5SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X5SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 5mm 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 SDAD40X5SB
The AirTAC SDAD40X5SB is a double-acting, double-rod compact cylinder engineered for symmetric operation. Because a 16mm rod exits both ends of the riveted body, the annular areas match, giving you 527.8 N of push and pull force at 0.5 MPa. This equal force prevents asymmetric loading on your tooling.
Designed for minimal axial footprint, this short body saves mounting depth where larger cylinders fail. It carries a built-in magnet for position sensing and features male M14x1.5 rod threads on both ends. The fixed NBR bumpers absorb end-of-stroke shock without requiring adjustment.
Airtac SDAD Double Rod Slim Cylinder SDAD40X5SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X5SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 5 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 SDAD40X5SB Is Used
Micro-Clamping Station
Uses the 5mm stroke and 527.8 N equal force to grip thin workpieces without twisting, leveraging the male M14x1.5 rods for direct tool mounting.
Dual-End Transfer Gate
Mounts a diverter on one end and a position dog on the other, utilizing the anti-rotation through-rod to maintain precise alignment during rapid 30-500 mm/s cycling.
Symmetric Punching Jig
Exploits the matched push and pull force to punch and retract evenly, preventing snags on delicate materials within a tight machine envelope.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X5SB the Right Cylinder?
Choosing this 40mm bore means sizing between the SDAD32 at 345.6 N and the SDAD50 at 824.7 N, both at 0.5 MPa. The 527.8 N output provides a safe working load around 317 N, or a 26.9 kg vertical lift with a 2:1 margin. The through-rod geometry resists twisting, letting you mount a tool on one male M14x1.5 end and a dog on the opposite.
This configuration includes the S magnet for AirTAC reed or electronic switches and the B male-thread rods. Remember that a standard cylinder drifts when air is lost; add an external rod lock or pilot-operated check valve if you need strict load holding. The PT1/8 port and 5mm stroke keep the assembly highly compact.
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 SDAD40X5SB FAQ
The force is identical in both directions due to the double-rod design: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical max of 108 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
Yes. The through-rod resists rotation and exits both ends with male M14x1.5 threads. You can drive a tool on one side while mounting an AirTAC reed or electronic switch target on the other for synchronized operation.
