Airtac SDAD Double Rod Slim Cylinder SDAD80X40SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X40SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm 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 SDAD80X40SB
The AirTAC SDAD80X40SB is a double-acting compact 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, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is essential when driving rigid loads that require consistent thrust and retraction without shifting dynamics.
Equipped with a built-in magnet for position sensing and male M22x1.5 rod threads on both ends, this 80 mm bore unit operates at 30-500 mm/s. The short body design minimizes axial mounting depth in tight machinery. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, absorbing shock reliably within the 40 mm stroke.
Airtac SDAD Double Rod Slim Cylinder SDAD80X40SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X40SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 40 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M14×1.5 female / M22×1.5 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 120 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SDAD80X40SB Is Used
Precision Guiding Jig
Drives a guided clamping fixture where the dual-end rod prevents twist during high-thrust positioning, utilizing the 2267.8 N equal force for symmetric clamping.
Vertical Lift Station
Raises a 115.6 kg payload using the male M22x1.5 threads for secure mounting, relying on the equal pull force to lower the load smoothly.
Dual-End Transfer Unit
Actuates a transfer arm on one end while a reed switch tracks position on the opposite end, fitting into shallow machine frames via the compact riveted body.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X40SB the Right Cylinder?
When sizing this model, compare its 2267.8 N output at 0.5 MPa against adjacent bores. Stepping down, the SDAD63 provides 1401.5 N, whereas stepping up to the SDAD100 yields 3524.9 N. For this 80 mm bore, a safe working load is approximately 1361 N, allowing a vertical lift of about 115.6 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and permits mounting a tool on one end with a dog on the opposite end.
This configuration includes the S magnet for AirTAC reed or electronic switches and the B option for male M22x1.5 rod threads at both ends. Air enters via the PT3/8 port. Remember that a standard cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the 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 SDAD80X40SB FAQ
The double-rod design provides equal force in both directions: 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa.
Yes, the through-rod exits both ends with male M22x1.5 threads, allowing you to drive a tool on one side and mount a dog or sensor target on the other while the rod resists rotation.
