Airtac SDAD Double Rod Slim Cylinder SDAD16X40
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X40 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø16mm bore, 40mm 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 SDAD16X40
The AirTAC SDAD16X40 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 on extend and retract, delivering an equal 86.4 N of push and pull force at 0.5 MPa. This symmetry is a major advantage when driving loads that require consistent kinetic energy in both directions.
With a 40 mm stroke and a short axial footprint, this 16 mm bore unit fits easily into tight machinery where round-body or profile cylinders cannot. The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one end and a dog or mechanical stop on the opposite end. End-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD16X40 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X40 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø16 mm |
| Stroke | 40 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 SDAD16X40 Is Used
Gripper Jaw Actuation
Drives opposed gripper fingers where the equal 86.4 N extend and retract forces ensure balanced clamping and release pressure on delicate components.
Reciprocating Transfer
Shuttles small parts back and forth across a 40 mm span, using the through-rod to prevent twisting during rapid directional changes.
Dual-End Tooling Mount
Mounts a pick-and-place nozzle on the front rod while using the opposite protruding rod end to trip an external mechanical dog at stroke completion.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X40 the Right Cylinder?
When sizing this model, compare its 86.4 N output at 0.5 MPa against adjacent bores. Stepping down to the SDAD12 yields 42.4 N, while moving up to the SDAD20 provides 131.9 N, making the 16 mm bore the right middle ground for moderate symmetric loads. A practical safe working load is approximately 52 N (about 60 percent of the 0.5 MPa figure), which translates to a vertical lift capacity of roughly 4.4 kg with a 2:1 safety margin.
This SKU has no piston magnet and cannot support reed or electronic switches; select the -S variant if position sensing is required. The female M3x0.5 rod-end threads and M5x0.8 air port are fixed by the bore. Note that a plain cylinder does not hold its load if air pressure drops or the valve is centred—the piston will drift. For 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 SDAD16X40 FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. It generates 86.4 N at 0.5 MPa, 121 N at 0.7 MPa, and a theoretical maximum of 18 kgf at 1.0 MPa in both directions.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S variant of this model, which adds the required internal magnet.
