Airtac SDAD Double Rod Slim Cylinder SDAD32X20B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD32X20B 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 SDAD32X20B
The AirTAC SDAD32X20B is a double-acting compact cylinder featuring a 32 mm bore and a 20 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 345.6 N at 0.5 MPa in either direction.
This specific SKU includes male M10x1.25 thread on both rod ends, allowing direct mounting of tooling on one side and a dog or fixture on the opposite side. The through-rod construction inherently resists twisting during operation. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD32X20B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD32X20B |
|---|---|
| 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 SDAD32X20B Is Used
Gripper Jaw Sync
Drives opposing gripper jaws with equal 345.6 N force in both directions, ensuring clamped parts remain perfectly centered during transfer.
Dual-End Transfer
Uses the male M10x1.25 threads on both ends to push a part on one side while simultaneously actuating a reject dog on the opposite end.
Anti-Rotation Stamping
Resists twisting forces during short 20 mm stamping strokes, maintaining tool alignment where a single rod might bind under offset loads.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD32X20B the Right Cylinder?
When sizing this unit, compare its 345.6 N @0.5 MPa output with neighboring bores. Dropping down to the SDAD25 yields 206.2 N, while stepping up to the SDAD40 provides 527.8 N. Based on the 345.6 N figure, a safe working load is approximately 207 N (about 60 percent capacity), which translates to a vertical lift capability of roughly 17.6 kg with a 2:1 safety margin.
The dual-end through-rod prevents rotation and enables dual-end actuation, but a plain cylinder drifts when air pressure is lost or the valve is centered. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This configuration confirms a 32 mm bore, 20 mm stroke, PT1/8 port, no piston magnet, and male M10x1.25 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 SDAD32X20B FAQ
The force is equal in both directions due to the double-rod design. It outputs 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. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept reed or electronic switches. You would need the SDAD32X20BS variant to use AirTAC magnetic sensors in the body grooves.
