Airtac SDAD Double Rod Slim Cylinder SDAD80X70SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X70SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 70mm 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 SDAD80X70SB
The AirTAC SDAD80X70SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber, the annular area remains identical on extend and retract, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetric output is highly advantageous for manipulating heavy loads without directional force bias.
Equipped with a built-in magnet for reed or electronic switches and male M22x1.5 thread on both rod ends, this 80 mm bore unit saves axial mounting depth compared to standard profile bodies. It handles a safe working load of about 1361 N, enabling a vertical lift of roughly 115.6 kg with a 2:1 safety margin. The fixed NBR bumpers decelerate the stroke ends, operating reliably at speeds between 30 and 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD80X70SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X70SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 SDAD80X70SB Is Used
Symmetric Lift Stations
Lifting 115.6 kg vertical loads using the equal 2267.8 N bi-directional force, ensuring smooth ascent and descent without momentum shifts.
Anti-Rotation Guiding
Driving a precision machining fixture where the 25 mm through-rod resists twisting torque, keeping the tool path perfectly straight.
Dual-End Transfer
Actuating a conveyor diverter with the male M22x1.5 rod pushing a product on one side while a dog trips a sensor on the opposite end.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X70SB the Right Cylinder?
When sizing this model, stepping down to the SDAD63 provides 1401.5 N at 0.5 MPa, whereas moving up to the SDAD100 yields 3524.9 N. The 80 mm bore strikes a balance for medium-heavy tooling. The through-rod design resists twisting and permits mounting a work tool on one end while a dog triggers a switch on the opposite end.
This configuration includes the S magnet for position sensing and the B option for male M22x1.5 rod threads on both ends, paired with a PT3/8 air port. Note that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near 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 SDAD80X70SB FAQ
Because the double-rod design creates equal annular areas, push and pull forces are identical. It generates 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa in both directions.
The through-rod resists mechanical twisting and allows you to mount a tool on one end and a sensor dog on the other. The S option provides a built-in magnet for AirTAC reed or electronic switches, while the B option provides male M22x1.5 threads on both rod ends.
