Airtac SDAD Double Rod Slim Cylinder SDAD32X20
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X20 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø32mm bore, 20mm 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 SDAD32X20
The AirTAC SDAD32X20 is a double-acting compact cylinder featuring a 32 mm bore and a 20 mm stroke. A piston rod protrudes from both ends of the riveted body, creating equal annular areas on each side. This geometry ensures push and pull forces match exactly at 345.6 N under 0.5 MPa, delivering symmetric thrust for demanding motion tasks.
The through-rod design inherently resists twisting, allowing you to mount a work tool on one end and a dog or limit switch on the opposite side. With a 12 mm rod diameter and PT1/8 port, this unit saves axial mounting depth. End-of-stroke energy is managed solely by a fixed NBR bumper, operating reliably across a 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD32X20 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X20 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø32 mm |
| Stroke | 20 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 SDAD32X20 Is Used
Gripper Jaw Sync
Drives opposing gripper jaws where the dual-end rod prevents twist and ensures identical 345.6 N clamping pressure during both extension and retraction.
Short-Stroke Punching
Executes 20 mm stamping operations in tight fixtures, relying on the fixed NBR bumper to absorb end-of-stroke shock without adjustable cushions.
Dual-End Transfer
Mounts a pusher plate on one rod tip and a mechanical dog on the opposite tip to trip external physical sensors in space-constrained assembly lines.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X20 the Right Cylinder?
When sizing this 32 mm bore unit, consider the neighbouring SDAD25 which yields 206.2 N at 0.5 MPa, and the larger SDAD40 providing 527.8 N at 0.5 MPa. The SDAD32X20 strikes a middle ground, offering a safe working load of roughly 207 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 17.6 kg with a 2:1 safety margin.
This specific SKU lacks the S magnet option, meaning it cannot host reed or electronic switches. The female M6x1.0 rod-end threads are standard. Remember that a standard cylinder drifts when air pressure drops or the valve centers; utilize an external rod lock or pilot-operated check valve if your application requires strict load holding.
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 SDAD32X20 FAQ
Because the double-rod design creates equal annular areas, the push and pull forces are identical. It generates 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a maximum theoretical output of 70 kgf at 1.0 MPa in both directions.
Yes, the through-rod extends from both sides, allowing you to drive a load on one end while using the opposite end for external mechanical tracking. The rod resists rotation, and the compact riveted body minimizes axial footprint.
