Airtac SDAD Double Rod Slim Cylinder SDAD20X5
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X5 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm bore, 5mm 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 SDAD20X5
The AirTAC SDAD20X5 is a double-acting compact cylinder featuring a 20mm bore and a 5mm stroke, with twin piston rods exiting the riveted body from both ends. Because the rod occupies each chamber equally, the annular area remains identical on extension and retraction, yielding an equal push and pull force of 131.9 N at 0.5 MPa. This symmetry prevents twisting and provides stable operation for short-travel tasks.
The short riveted body significantly reduces axial mounting depth where a standard round-body cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet and cannot support magnetic sensing, while the bore dictates an 8mm rod diameter and an M5x0.8 air port.
Airtac SDAD Double Rod Slim Cylinder SDAD20X5 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X5 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 5 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 90 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 (Ø20mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 SDAD20X5 Is Used
Micro-Clamp Actuation
Provides equal 131.9 N clamping and release force at 0.5 MPa for delicate machined parts, preventing grip distortion on a 5mm travel.
Symmetric Ejector Pusher
Drives a tool on one end while the opposite rod end pushes a part out, utilizing the anti-rotation geometry to maintain precise alignment.
Shallow Pick-and-Place
Fits into tight transfer stations where axial depth is restricted, using the compact riveted body to execute short 5mm component placements.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X5 the Right Cylinder?
When sizing this 20mm bore, consider the SDAD16 which provides 86.4 N at 0.5 MPa, or step up to the SDAD25 offering 206.2 N at 0.5 MPa. The SDAD20X5 strikes a middle ground with 131.9 N at 0.5 MPa, translating to a safe working load of roughly 79 N or a vertical lift of about 6.7 kg with a 2:1 margin.
The through-rod design allows mounting a tool on one end and a dog on the opposite end simultaneously. Note that a plain cylinder does not hold its load on air loss or valve centering, as the piston drifts and the fixed bumper only decelerates near stroke end; use an external rod lock or pilot-operated check valve for load holding. This configuration features a 5mm stroke, M5x0.8 port, female M4x0.7 rod-end threads, and no magnet.
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 SDAD20X5 FAQ
The double-rod design provides equal force in both directions: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 27 kgf at 1.0 MPa.
No, this specific SKU does not have a piston magnet and cannot take a magnetic switch. You would need the -S variant to use reed or electronic switches for position sensing.
