Airtac SDAD Double Rod Slim Cylinder SDAD16X20B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X20B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø16mm bore, 20mm 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 SDAD16X20B
The AirTAC SDAD16X20B is a compact double-acting cylinder featuring a 6 mm piston rod exiting both ends of its riveted body. Because the rod occupies each chamber, the annular area remains identical in both directions, yielding an equal push and pull force of 86.4 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic energy regardless of travel direction.
This specific SKU includes male M5x0.8 rod threads at both ends and utilizes an M5x0.8 air port. The short body design drastically reduces required axial mounting depth compared to standard round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD16X20B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X20B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 20 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø16mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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 SDAD16X20B Is Used
Symmetric Transfer
Drives a light pick-and-place shuttle where matching 86.4 N force on extension and retraction prevents jarring stops during rapid part transfers.
Anti-Twist Gripper
Mounts a small angular jaw on one male M5x0.8 end while the opposing rod end stabilizes the assembly to resist torsional deflection on tight clearances.
Dual-End Ejector
Uses the 20 mm stroke to push a small electronic component out of a fixture on one side while simultaneously triggering a mechanical dog on the opposite end.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X20B the Right Cylinder?
When sizing this 16 mm bore unit, consider the SDAD12 which provides 42.4 N at 0.5 MPa, or step up to the SDAD20 which outputs 131.9 N at 0.5 MPa. The through-rod geometry inherently resists twisting and permits mounting a tool on one end while using the opposite end for a secondary mechanism. Based on the 86.4 N output, a safe working load is roughly 52 N, allowing a vertical lift of about 4.4 kg with a 2:1 safety margin.
Note that this configuration lacks a piston magnet, so position sensing is not possible without switching to the -S variant. Furthermore, a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. For secure load holding, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SDAD16X20B FAQ
The double-rod design provides equal force in both directions: 86.4 N at 0.5 MPa and 121 N at 0.7 MPa. The theoretical maximum is 18 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not have a built-in piston magnet. You must select the -S option to use AirTAC reed or electronic switches. The through-rod design still allows dual-end mounting via the male M5x0.8 threads.
