Airtac SDAD Double Rod Slim Cylinder SDAD80X75
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X75 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 75mm 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 SDAD80X75
The AirTAC SDAD80X75 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 exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetry is essential when driving loads that must resist twisting or when you need to mount a tool on one end and a dog on the opposite side.
The 80 mm bore uses a PT3/8 port and a 25 mm rod, yielding a theoretical maximum of 463 kgf at 1.0 MPa. End-of-stroke energy is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning you should externally slow high-speed approaches. This specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X75 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X75 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 75 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 SDAD80X75 Is Used
Web Guiding Brakes
Uses the through-rod's anti-rotation properties to hold a braking flap steady against a moving material web, ensuring the 25 mm rod resists twisting under asymmetric friction.
Symmetric Lift Stations
Drives a vertical lifting carriage where the equal 2267.8 N extend and retract forces prevent jerky transitions when raising or lowering a 115 kg fixture.
Dual-End Transfer
Mounts a pusher jaw on the front rod and a mechanical dog on the rear rod, allowing an external limit switch to track the 75 mm stroke without interfering with the work area.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X75 the Right Cylinder?
When sizing this model, compare it directly with its neighbors: the smaller SDAD63 provides 1401.5 N at 0.5 MPa, while the larger SDAD100 offers 3524.9 N. The SDAD80X75 sits comfortably in the middle for applications needing roughly 2267.8 N of symmetric thrust. A safe working load is about 1361 N, allowing a vertical lift of approximately 115.6 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air is removed or the valve centers, as the fixed bumper only decelerates near the stroke end and acts as no lock. For load-holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration specifies female M14x1.5 rod-end threads, a 75 mm stroke, and no magnet.
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 SDAD80X75 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.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches in the body grooves, you must select the -S variant. The through-rod still allows you to mount a physical dog on the opposite end for external mechanical sensing.
