Airtac SDAD Double Rod Slim Cylinder SDAD80X65SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X65SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 65mm 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 SDAD80X65SB
The AirTAC SDAD80X65SB 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, giving you 2267.8 N of push and pull force at 0.5 MPa. This symmetry is essential when driving loads that require consistent momentum in both strokes.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, and male M22x1.5 threads (-B) on both 25 mm rods, it provides flexible dual-end mounting. The short body design saves axial depth compared to standard profile cylinders, while the fixed NBR bumper absorbs end-of-stroke shock without requiring adjustment.
Airtac SDAD Double Rod Slim Cylinder SDAD80X65SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X65SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 65 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 SDAD80X65SB Is Used
Web Guiding Mechanism
Utilizes the dual male M22x1.5 rod ends to tension and steer material uniformly, relying on the 2267.8 N of equal bidirectional force to prevent sagging.
Elevator Platform Drive
Lifts a 115.6 kg payload vertically with a 2:1 safety margin, using the through-rod to resist torsional twist during ascent and descent.
Symmetric Transfer Arm
Mounts a gripper on one side and a magnetic switch dog on the opposite end, maintaining perfectly balanced 3175 N dynamics at 0.7 MPa.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X65SB the Right Cylinder?
When sizing this 80 mm bore, consider the SDAD63 which outputs 1401.5 N at 0.5 MPa, or step up to the SDAD100 providing 3524.9 N at 0.5 MPa. The SDAD80X65SB sits comfortably in the middle, offering a safe working load of roughly 1361 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting during operation, allowing you to mount a tool on one end and a position dog on the other. Remember that a plain cylinder drifts if air pressure drops or the valve centers; use an external rod lock or pilot-operated check valve for strict load holding. This configuration includes the -S magnet, -B male M22x1.5 rod threads, a 65 mm stroke, and PT3/8 ports.
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 SDAD80X65SB FAQ
The push and pull forces are identical because of the double-rod design. 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. The maximum operating pressure is 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end points; it does not act as a brake. For load holding, you must install an external rod lock or a pilot-operated check valve.
