Airtac SDAD Double Rod Slim Cylinder SDAD80X15SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X15SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 15mm 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 SDAD80X15SB
The AirTAC SDAD80X15SB is a compact double-acting cylinder featuring a 15 mm stroke and an 80 mm bore. A piston rod extends from both ends of the riveted body, creating identical annular areas. This geometry ensures push and pull forces match exactly at 2267.8 N each way under 0.5 MPa, which is highly beneficial for symmetric loads.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this model also features male-thread (-B) M22x1.5 rods on both ends. The short footprint saves axial mounting depth, while the fixed NBR bumpers absorb end-of-stroke shock. Operating speed ranges from 30-500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD80X15SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X15SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 15 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 SDAD80X15SB Is Used
Symmetric Lift Station
Lifts 115.6 kg vertically with a 2:1 margin using the equal 2267.8 N push/pull force, ensuring stable elevation without twisting.
Dual-End Transfer
Drives a primary gripper on one end while mounting a position dog on the opposite M22x1.5 male rod for external switch tracking.
Riveting Head Feed
Advances a heavy riveting tool with 1361 N safe working load, relying on the through-rod to resist torsional side loads during impact.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X15SB the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD63 provides 1401.5 N at 0.5 MPa, while the SDAD100 offers 3524.9 N. The SDAD80X15SB provides a safe working load of roughly 1361 N (about 60% of its 2267.8 N capacity), allowing a vertical lift of approximately 115.6 kg with a 2:1 safety margin. The through-rod design resists twisting and permits dual-end tooling.
This configuration includes a PT3/8 port and male M22x1.5 rod threads. Remember that a plain cylinder drifts when air 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 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 SDAD80X15SB FAQ
Because the double-rod design creates equal annular areas, force is identical in both directions: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near its end points. For load holding, you must use an external rod lock or pilot-operated check valve.
