Airtac SDAD Double Rod Slim Cylinder SDAD80X80B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X80B 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 SDAD80X80B
The AirTAC SDAD80X80B 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 on extend and retract, yielding exactly 2267.8 N of force at 0.5 MPa in each direction. This symmetry is crucial for mechanisms demanding balanced push and pull kinetics.
Equipped with male M22x1.5 threads on the 25 mm rods, this unit saves axial mounting depth while allowing you to drive a tool on one end and mount a dog on the opposite end. It uses a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot support reed or electronic switches without the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X80B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X80B |
|---|---|
| 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 SDAD80X80B Is Used
Web Guiding Brakes
Uses the equal 2267.8 N bidirectional force to tension and guide wide material webs without skewing, leveraging the anti-twist through-rod for stable tracking.
Symmetric Lift Stations
Drives a lifting platform from one rod end while the opposite end actuates a mechanical dog, ensuring balanced vertical lift of heavy 115 kg fixtures.
Dual-End Transfer Arms
Mounts a male M22x1.5 tool on one side and a secondary gripper on the other to push and pull parts simultaneously within a tight 80 mm stroke window.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X80B the Right Cylinder?
When sizing this 80 mm bore, compare it directly with its neighbors. Dropping down to the SDAD63 provides 1401.5 N at 0.5 MPa, whereas stepping up to the SDAD100 yields 3524.9 N at 0.5 MPa. This SDAD80X80B sits comfortably in the middle, offering a safe working load of roughly 1361 N (about 60 percent of the 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, but remember that a standard cylinder drifts if air pressure drops or the valve centers. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This specific configuration includes an 80 mm stroke, PT3/8 port, and male M22x1.5 rod threads on both ends.
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 SDAD80X80B 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.
No, this specific SKU lacks a piston magnet. You must select the -S variant to use AirTAC reed or electronic switches for position sensing.
