Airtac SDAD Double Rod Slim Cylinder SDAD20X5SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X5SB 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 SDAD20X5SB
The AirTAC SDAD20X5SB is a compact double-acting cylinder featuring a 20mm bore and a 5mm stroke, with piston rods exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding exactly 131.9 N of force at 0.5 MPa in both directions. This symmetric output is ideal for delicate gripping tasks requiring balanced push and pull.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this unit provides reliable position feedback. The -B option specifies male M6x1.0 rod threads at both ends. Its shallow 5mm movement and short body profile save axial mounting depth, while the fixed NBR bumper decelerates the stroke end without acting as an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD20X5SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X5SB |
|---|---|
| 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 SDAD20X5SB Is Used
Micro-Clamp Actuation
Uses the 5mm stroke and equal 131.9 N bidirectional force to grip small electronic components securely without overshooting.
Symmetric Push-Pull Transfer
Exploits the dual-end male M6 rods to drive a part forward while simultaneously triggering a reed switch on the opposite end.
Anti-Rotation Guide
Leverages the through-rod design to prevent twisting during short vertical pressing tasks where lateral space is highly restricted.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X5SB the Right Cylinder?
When sizing this 20mm bore actuator, 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 SDAD20X5SB provides a safe working load of roughly 79 N, about 60 percent of its 131.9 N rating, translating to a vertical lift capacity near 6.7 kg with a 2:1 safety margin. The through-rod geometry resists twisting, allowing you to mount a tool on one end and a position dog on the opposite side.
Confirm the 20mm bore, 5mm stroke, M5x0.8 air port, male M6x1.0 rod threads, and the integrated magnet. Note that a plain cylinder does not hold its load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a 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 SDAD20X5SB FAQ
The force is equal in both directions due to the double-rod design. It generates 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.
Yes, the through-rod exits both ends, allowing you to attach a work tool to the male M6 thread on one side and a position dog for a reed or electronic switch on the opposite end.
