Airtac SDAD Double Rod Slim Cylinder SDAD20X110S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X110S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm bore, 110mm 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 SDAD20X110S
The AirTAC SDAD20X110S 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 in each direction, yielding equal push and pull forces of 131.9 N at 0.5 MPa. This symmetric thrust is ideal for balanced loads.
This unit carries the S option for a built-in piston magnet compatible with AirTAC reed or electronic switches. The 110 mm stroke exceeds the standard 100 mm maximum for this 20 mm bore, making it a non-standard made-to-order item. It features an 8 mm rod diameter, an M5x0.8 port, and fixed NBR bumpers that decelerate the stroke ends.
Airtac SDAD Double Rod Slim Cylinder SDAD20X110S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X110S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 110 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 SDAD20X110S Is Used
Symmetric Gripper Actuation
Drives a dual-jaw mechanism where the equal 131.9 N extend and retract forces maintain consistent gripping pressure on precision parts.
Dual-End Transfer Pusher
Mounts a pusher plate on the front rod and a magnetic dog on the rear to trigger a reed switch, saving axial space in transfer lines.
Anti-Rotation Lift Station
The through-rod geometry prevents twisting during vertical lifts of 6.7 kg, ensuring component alignment without external guides.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X110S the Right Cylinder?
When sizing this bore, note the SDAD16 provides 86.4 N at 0.5 MPa, whereas the SDAD25 offers 206.2 N. The 131.9 N output here gives a safe working load of roughly 79 N (about 60 percent of capacity) and a vertical lift capacity of 6.7 kg with a 2:1 margin. The through-rod resists twisting and allows mounting a tool on one end and a position dog on the opposite side.
Confirm the 20 mm bore, 110 mm non-standard stroke, M5x0.8 port, female M4x0.7 rod threads, and the S magnet. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near stroke end. For load holding without live pressure, install an external rod lock or 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 SDAD20X110S 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. Operating pressure ranges from 0.15 to 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke end and does not act as a brake. For load holding, you need an external rod lock or pilot-operated check valve.
