Airtac SDAD Double Rod Slim Cylinder SDAD80X45SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X45SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 45mm 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 SDAD80X45SB
The AirTAC SDAD80X45SB is a double-acting, double-rod compact cylinder engineered for symmetric actuation. Because the piston rod exits both ends of the riveted body, the annular areas match, yielding identical push and pull forces of 2267.8 N at 0.5 MPa. This geometric balance prevents twisting and provides a stable platform for heavy-duty tooling.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this unit features male-threaded (-B) M22x1.5 rods at both ends. The short body design drastically reduces axial mounting depth compared to conventional cylinders. End-of-stroke deceleration is handled by a fixed NBR bumper, operating smoothly within the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD80X45SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X45SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 45 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 SDAD80X45SB Is Used
Precision Grinding Fixture
The through-rod prevents rotational drift on a grinding fixture, ensuring the male M22x1.5 end holds the part perfectly square while delivering 2267.8 N of symmetric clamping force.
Heavy-Duty Lift Station
Ideal for lifting 115.6 kg payloads vertically with a 2:1 safety margin, utilizing the equal push/pull geometry to maintain smooth descent without sudden load shifts.
Dual-End Transfer Mechanism
Mount a gripper on one end and a magnetic switch dog on the opposite end to synchronize part handoff, leveraging the compact riveted body to save axial space in tight cells.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X45SB the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbors: the SDAD63 provides 1401.5 N at 0.5 MPa, while the SDAD100 offers 3524.9 N. The SDAD80X45SB hits a sweet spot with 2267.8 N at 0.5 MPa, translating to a safe working load of roughly 1361 N (60% capacity) or a 115.6 kg vertical lift with a 2:1 margin. Its through-rod design allows driving a tool on one end while mounting a position dog on the opposite end.
This configuration includes the -S magnet for sensing and -B male M22x1.5 rod threads. Air enters via PT3/8 ports. Note that a standard cylinder drifts when air is lost or the valve centers—the fixed NBR bumper only decelerates near stroke end. For strict 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 SDAD80X45SB 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, with a proof pressure of 1.5 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one end and mount a dog for reed or electronic switches on the other. The male M22x1.5 threads on both ends simplify fixture attachment.
