Airtac SDAD Double Rod Slim Cylinder SDAD16X40SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD16X40SB 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 SDAD16X40SB
The AirTAC SDAD16X40SB 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 stays identical, yielding an equal push and pull force of 86.4 N at 0.5 MPa. This symmetry is ideal for moving loads without inducing asymmetric torque.
Equipped with a built-in magnet for reed or electronic switches, this 16 mm bore unit accepts M5x0.8 male threads on both rod ends. The short footprint minimizes axial mounting depth, while fixed NBR bumpers absorb end-of-stroke shocks across its 40 mm travel at speeds of 30-500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD16X40SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD16X40SB |
|---|---|
| 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 SDAD16X40SB Is Used
Gauge Calibrator
Drives a measuring head with identical 86.4 N extend and retract forces, preventing bias in precision calibration jigs.
Dual-End Transfer
Uses the male M5x0.8 rods on both sides to push a part on one end while triggering a reed switch dog on the opposite end.
PCB Edge Guide
Resists rotational twist via the through-rod to keep delicate electronic panels aligned during a 40 mm transfer stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD16X40SB the Right Cylinder?
When sizing this unit, consider the adjacent bores: stepping down to SDAD12 provides 42.4 N at 0.5 MPa, whereas moving up to SDAD20 offers 131.9 N. The SDAD16X40SB provides a safe working load of roughly 52 N (about 60% of its 86.4 N capacity) and can vertically lift approximately 4.4 kg with a 2:1 safety margin. The through-rod design prevents twisting and allows mounting a tool on one end with a position dog on the opposite side.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve centers, as the fixed bumper only decelerates near the stroke end rather than locking the load. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This specific configuration includes the S magnet for sensing and the B option for male M5x0.8 rod threads on both ends.
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 SDAD16X40SB FAQ
The double-rod design provides equal force 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.
Yes, the through-rod resists twisting and exits both ends, allowing you to drive a tool on one side while mounting an electronic or reed switch dog on the other, enabled by the built-in S magnet.
