Airtac SDAD Double Rod Slim Cylinder SDAD16X20SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X20SB 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 SDAD16X20SB
The AirTAC SDAD16X20SB is a compact double-acting cylinder featuring a 6 mm piston rod exiting both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, yielding equal push and pull forces of 86.4 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent motion without twisting.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this 20 mm stroke unit allows position sensing on one end while driving a tool on the other. The -B option specifies male M5x0.8 rod threads at both ends, and the short body depth saves valuable axial mounting space in tight machinery.
Airtac SDAD Double Rod Slim Cylinder SDAD16X20SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X20SB |
|---|---|
| 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 SDAD16X20SB Is Used
Symmetric Transfer Jaws
Drives a gripper on one end while the opposite rod carries a dog, using the equal 86.4 N push and pull force to move small parts without rotational twist.
Compact Pin Insertion
Fits into shallow machinery envelopes using its short riveted body, driving a male M5 threaded tooling head to press pins with consistent bidirectional force.
Dual-End Sorting Flap
Actuates a routing gate on one side and triggers an electronic switch on the other, relying on the through-rod to maintain stable alignment across 20 mm of travel.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X20SB the Right Cylinder?
When sizing this 16 mm bore, compare its 86.4 N force at 0.5 MPa against its neighbors: the smaller SDAD12 provides 42.4 N, while the larger SDAD20 offers 131.9 N. A safe working load is roughly 52 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 4.4 kg with a 2:1 margin. The through-rod geometry resists rotation and enables dual-end mounting.
This configuration includes the -S magnet for sensing and -B male M5x0.8 rod threads on both ends, operating via an M5x0.8 port. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed NBR 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 SDAD16X20SB FAQ
Because the double-rod design creates equal annular areas, force is identical in both directions: 86.4 N at 0.5 MPa, 121 N at 0.7 MPa, and a theoretical maximum of 18 kgf at 1.0 MPa.
The through-rod resists twisting and lets you mount tooling on one end while using the built-in magnet with a reed or electronic switch on the other. The -B option provides male M5x0.8 threads on both rod ends for secure fixture attachment.
