Airtac SDAD Double Rod Slim Cylinder SDAD20X5B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X5B 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 SDAD20X5B
The AirTAC SDAD20X5B is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies each chamber equally, the annular area remains constant, yielding identical push and pull forces of 131.9 N at 0.5 MPa. This symmetric output is ideal for balancing loads without tweaking pressure regulators.
Designed for tight spaces, the short 5 mm stroke saves axial mounting depth where larger profile cylinders cannot fit. The through-rod geometry inherently resists twisting, while the male M6x1.0 thread on both rod ends provides secure tool mounting. End shock is managed by a fixed NBR bumper, which decelerates the stroke end without acting as a lock.
Airtac SDAD Double Rod Slim Cylinder SDAD20X5B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X5B |
|---|---|
| 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 SDAD20X5B Is Used
Gripper Jaw Actuation
Provides equal 131.9 N clamping and release forces, ensuring grippers hold delicate components without asymmetric crushing during robotic pick and place.
Short Stroke Diversion
The 5 mm stroke and anti-rotation through-rod deliver precise, twist-free product deflecting on high-speed packaging lines where space is severely restricted.
Symmetric Pressing Jig
Male M6x1.0 rods on both ends allow mounting a pressing tool on one side and a mechanical stop on the other, maintaining perfect parallelism for light assembly tasks.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X5B the Right Cylinder?
When sizing this unit, compare its 131.9 N output at 0.5 MPa against its neighbors. Dropping down to the SDAD16 yields 86.4 N, whereas stepping up to the SDAD25 provides 206.2 N. This makes the 20 mm bore the right middle ground for applications needing roughly 79 N of safe working load (about 60 percent of the 0.5 MPa figure) or a 6.7 kg vertical lift with a 2:1 margin.
The through-rod design prevents rotation and allows driving a tool on one end while using the opposite end for a mechanical dog. Note that a plain cylinder drifts when air is lost or the valve centers; the bumper only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for load holding. This SKU features an M5x0.8 port, a 5 mm stroke, and male M6x1.0 rod threads, but lacks the S magnet, meaning it cannot accept reed or electronic switches.
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 SDAD20X5B FAQ
The double-rod design provides equal force in both directions: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa. The theoretical maximum is 27 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod exits both sides with male M6x1.0 threads, allowing you to drive a tool on one end and mount a dog on the other. This geometry also resists twisting, though this specific SKU lacks the S magnet for switch sensing.
