Airtac SDAD Double Rod Slim Cylinder SDAD40X40B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X40B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 40mm 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 SDAD40X40B
The AirTAC SDAD40X40B is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area remains constant, delivering identical push and pull forces of 527.8 N at 0.5 MPa. This symmetric output is ideal for balanced actuation tasks.
Equipped with male M14x1.5 threads on both 16 mm rod ends, this variant simplifies direct mechanical mounting. The short body design saves axial depth in tight machinery, while fixed NBR bumpers absorb end-of-stroke impacts. Note this specific SKU lacks a piston magnet, so position sensing is not supported.
Airtac SDAD Double Rod Slim Cylinder SDAD40X40B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X40B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 40 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 SDAD40X40B Is Used
Gripper Synchronization
Drives opposing gripper jaws with equal 527.8 N force in both directions, ensuring parallel clamping on delicate extrusions without rotational deflection.
Dual-End Transfer
Mounts a pick-and-place head on one male M14x1.5 rod end while the opposite side mechanically links to a secondary gantry for synchronized part handoff.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X40B the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD32 provides 345.6 N at 0.5 MPa, while the SDAD50 offers 824.7 N.
The dual-end through-rod geometry prevents twisting and permits driving a tool on one side while mounting a dog on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; utilize an external rod lock or pilot-operated check valve for strict load holding. This configuration includes PT1/8 ports, a 40 mm stroke, and male M14x1.5 rod threads.
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 SDAD40X40B FAQ
The push and pull forces are identical due to the double-rod design. It generates 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one male M14x1.5 end while using the other for mechanical linking. This geometry also prevents rod rotation during operation.
