Airtac SDAD Double Rod Slim Cylinder SDAD80X80SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X80SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 80mm 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 SDAD80X80SB
The AirTAC SDAD80X80SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding exactly 2267.8 N of force at 0.5 MPa in each direction. This symmetric output is ideal for balanced tooling loads.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, the unit provides reliable position feedback. The -B option specifies male M22x1.5 threads on the 25 mm rods at both ends, while the short body profile saves axial mounting depth. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X80SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X80SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 80 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 SDAD80X80SB Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to steer material rolls with precision, maintaining alignment via symmetric push and pull forces.
Dual-End Transfer Shuttle
Mounts a grip on the front rod and a position dog on the rear, moving 115.6 kg payloads horizontally between machining stations.
Balanced Lift Fixture
Raises and lowers heavy platens where equal force both ways prevents sagging, relying on the 2267.8 N capacity at 0.5 MPa.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X80SB 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. This model provides a safe working load of roughly 1361 N, allowing a vertical lift of approximately 115.6 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and permits driving a tool on one end while mounting a dog on the opposite side.
This configuration includes an 80 mm stroke, PT3/8 air port, and male M22x1.5 rod threads. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near 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 SDAD80X80SB FAQ
The force is equal in both directions due to the double-rod design: 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 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 reed or electronic switch dog on the other. The design also resists mechanical twisting during operation.
