Airtac SDAD Double Rod Slim Cylinder SDAD32X40SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X40SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø32mm 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 SDAD32X40SB
The AirTAC SDAD32X40SB is a double-acting, double-rod compact cylinder engineered with a 32 mm bore and 40 mm stroke. Because the 12 mm piston rod exits both ends, the annular area remains identical in both chambers, yielding perfectly symmetric thrust of 345.6 N at 0.5 MPa. This equal push and pull capacity makes it highly reliable for reversing loads.
This specific configuration includes a built-in piston magnet for position sensing alongside male M10x1.25 rod threads on both ends. The short riveted body drastically reduces axial mounting depth compared to standard round-body options. 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 SDAD32X40SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X40SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 40 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M6×1.0 female / M10×1.25 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 (Ø32mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 SDAD32X40SB Is Used
Symmetric Transfer
Drives a gripper on the front rod and a dog on the rear, using the equal 345.6 N bidirectional force to shuttle parts smoothly without rotational deflection.
Dual-End Stamping
Mounts a male M10x1.25 threaded tooling head on each end to press small components alternately, maximizing cycle rates within a tight 40 mm stroke.
Balanced Lift
Raises and lowers a 17.6 kg vertical payload safely, leveraging the anti-rotation through-rod to keep the platform perfectly aligned without external guides.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X40SB the Right Cylinder?
When sizing this unit, compare its 345.6 N output at 0.5 MPa against neighboring bores: the SDAD25 provides 206.2 N, while the SDAD40 offers 527.8 N. A safe working load is roughly 207 N, allowing a vertical lift of about 17.6 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and permits driving a tool on one end while mounting a dog on the opposite side.
Remember that a plain compact cylinder drifts when air pressure is lost or the valve centers, as the fixed bumper only decelerates near stroke end rather than locking the load. For secure load holding, integrate an external rod lock or pilot-operated check valve. This SDAD32X40SB variant features a PT1/8 port, the -S magnet for reed or electronic switches, and the -B male M10x1.25 rod threads on both extensions.
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 SDAD32X40SB FAQ
The double-rod design provides equal force in both directions: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical maximum of 70 kgf at 1.0 MPa. This allows a safe working load of about 207 N, or a 17.6 kg vertical lift with a 2:1 margin.
The through-rod resists twisting and lets you mount tooling on one end while tracking position with a reed or electronic switch on the other. The -B option specifies male M10x1.25 threads on both rod ends, providing secure mechanical attachment for your fixtures.
