Airtac SDAD Double Rod Slim Cylinder SDAD20X10N
The AirTAC SDAD Double Rod Slim Cylinder SDAD20X10N is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm bore, 10mm 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 SDAD20X10N
The AirTAC SDAD20X10N is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding 131.9 N of force at 0.5 MPa in each direction. This symmetric output is ideal for balanced tooling.
With a 10 mm stroke and an 8 mm rod diameter, this thin-profile unit saves axial mounting depth where standard bodies will not fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot directly host reed or electronic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD20X10N Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X10N |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 10 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 SDAD20X10N Is Used
Short-Stroke Pinching
Provides symmetric 131.9 N clamping force on both open and close strokes for compact gripper jaws in tight assembly cells.
Dual-End Transfer
Drives a part pusher on the front rod while the rear rod simultaneously actuates a mechanical dog for timing synchronization.
Anti-Rotation Lift
Raises and lowers delicate electronic test fixtures without twisting, utilizing the inherent torsional resistance of the double-rod geometry.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X10N the Right Cylinder?
When sizing this 20 mm bore, compare its 131.9 N @0.5 MPa capacity against adjacent models: the SDAD16 provides 86.4 N, while the SDAD25 offers 206.2 N.
The through-rod design prevents twisting and permits driving a tool on one end while mounting a dog on the opposite side. Remember that a plain cylinder drifts on air loss or valve centering—the fixed bumper only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for load holding. This configuration uses an M5x0.8 port, female M4x0.7 rod threads, and operates at 30-500 mm/s.
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 SDAD20X10N 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. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not have a built-in piston magnet, so it cannot host reed or electronic switches. You would need the -S option variant to utilize the body sensor grooves for position detection.
