Airtac SDAD Double Rod Slim Cylinder SDAD80X55S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X55S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 55mm 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 SDAD80X55S
The AirTAC SDAD80X55S is a double-acting, double-rod compact cylinder engineered for symmetric load handling. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This geometric balance prevents twisting and ensures stable actuation throughout the 55 mm travel.
Equipped with a built-in piston magnet (-S), this unit supports AirTAC reed or electronic switches for end-of-stroke detection. The short body design drastically reduces axial mounting depth compared to conventional round-body cylinders. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X55S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X55S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 55 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 SDAD80X55S Is Used
Symmetric Lift Station
Utilizes the 2267.8 N equal bidirectional force to raise and lower heavy platens without inducing twisting moments during vertical transit.
Dual-End Tooling Drive
Mounts a forming die on the primary rod end while a dog triggers an electronic switch on the opposite end within the tight 55 mm stroke.
Heavy Transfer Gate
Employs the anti-rotation through-rod to push heavy pallets laterally, resisting side torque in compact conveyor routing modules.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X55S the Right Cylinder?
When sizing this 80 mm bore model, compare it against adjacent options: the smaller SDAD63 provides 1401.5 N at 0.5 MPa, while the larger SDAD100 offers 3524.9 N at 0.5 MPa. The SDAD80X55S strikes a middle ground, offering a safe working load of roughly 1361 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity of approximately 115.6 kg with a 2:1 safety margin.
This configuration features a 25 mm rod diameter, a PT3/8 air port, and female M14x1.5 rod-end threads on both ends. The through-rod design allows you to mount a work tool on one side and a position dog on the opposite side. Remember that a standard cylinder drifts when air is lost or the valve is centered; utilize an external rod lock or pilot-operated check valve for secure load holding.
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 SDAD80X55S FAQ
The double-rod design provides equal force 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. The operating pressure range is 0.15-1.0 MPa.
Yes, the through-rod extends from both ends, allowing you to drive a tool on one side and mount a detection dog on the other. The built-in magnet works with AirTAC reed or electronic switches, and the fixed NBR bumper decelerates the stroke end.
