Airtac SDAD Double Rod Slim Cylinder SDAD32X40S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X40S 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 SDAD32X40S
The AirTAC SDAD32X40S is a double-acting, double-rod compact cylinder featuring a 32mm bore and 40mm stroke. Because the piston rod exits both ends, the annular area remains identical in each chamber, ensuring push force equals pull force at 345.6 N for 0.5 MPa. This symmetric output is perfect for balanced actuation. The short riveted body drastically reduces axial mounting depth compared to standard round-body options.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The 12mm through-rod inherently resists twisting, allowing you to mount a work tool on one end and a position dog on the opposite side. End-of-stroke energy is managed strictly by a fixed NBR bumper, decelerating the piston without adjustable air cushioning.
Airtac SDAD Double Rod Slim Cylinder SDAD32X40S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X40S |
|---|---|
| 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 SDAD32X40S Is Used
Gripper Jaw Sync
Drives opposing gripper fingers with equal 345.6 N force in both directions, ensuring perfectly centered clamping on machined parts.
Dual-End Transfer
Mounts a pickup tool on one rod end and a magnetic dog on the other, allowing external switch tracking while the compact body fits tight shuttle spaces.
Lift and Lower Station
Lifts 17.6 kg vertical loads safely with a 2:1 margin, relying on the through-rod to prevent platform twist during rapid 30-500 mm/s elevation cycles.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X40S the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD25 yields 206.2 N at 0.5 MPa, while the larger SDAD40 provides 527.8 N at 0.5 MPa. The 32mm bore offers a calculated safe working load of roughly 207 N, translating to a vertical lift capacity of about 17.6 kg with a 2:1 safety margin. This makes the SDAD32X40S an optimal middle ground for moderate force requirements.
This configuration includes the -S magnet for switch readiness and female M6x1.0 rod-end threads on both ends, utilizing a PT1/8 port. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not lock the load. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
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 SDAD32X40S FAQ
The push and pull forces are identical due to the double-rod design. It generates 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke at the end caps and does not act as a brake. For load holding, you must install an external rod lock or a pilot-operated check valve.
