Airtac SDAD Double Rod Slim Cylinder SDAD16X25S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X25S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø16mm bore, 25mm 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 SDAD16X25S
The AirTAC SDAD16X25S 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, delivering an equal push and pull force of 86.4 N at 0.5 MPa. This symmetry is highly advantageous when driving loads that require consistent kinetic energy on extension and retraction.
Fitting a 16 mm bore and 25 mm stroke into a minimal axial footprint saves valuable machine depth. The integrated -S piston magnet allows tracking via reed or electronic switches, while the 6 mm rods resist twisting during transit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD16X25S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X25S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 25 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 SDAD16X25S Is Used
Symmetric Transfer Chuck
Utilizes the 86.4 N equal bidirectional force to securely grip and release delicate wafers without asymmetric acceleration.
Anti-Rotation Guide Pin
Exploits the dual-exit through-rod to resist twisting while aligning thin sheet metal panels in a confined riveting jig.
Dual-End Pick & Place
Drives a suction cup on the front stroke while a rear-mounted dog triggers an electronic switch at 25 mm extension.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X25S the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD12 yields 42.4 N at 0.5 MPa, while moving up to the SDAD20 provides 131.9 N. Based on the 86.4 N output, a safe working load is approximately 52 N (around 60 percent capacity), which translates to a vertical lift capability of roughly 4.4 kg with a 2:1 safety margin. The through-rod geometry prevents rotation and permits mounting a tool on one end with a position dog on the opposite side.
This configuration specifies a 16 mm bore, 25 mm stroke, and an M5x0.8 air port. The rod-end thread is female M3x0.5, and the included magnet supports AirTAC reed or solid-state switches. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates the stroke end. For secure load holding without live pressure, install an external rod lock or a 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 SDAD16X25S FAQ
The push and pull forces are identical because the rod occupies both chambers. It generates 86.4 N at 0.5 MPa and 121 N at 0.7 MPa, with a theoretical maximum of 18 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod design allows you to drive a tool on one end while using the opposite end to trigger a reed or electronic switch via the built-in -S magnet. The dual rods also provide excellent resistance to mechanical twisting during lateral loads.
