Airtac SDAD Double Rod Slim Cylinder SDAD80X20S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X20S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 20mm 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 SDAD80X20S
The AirTAC SDAD80X20S is a double-acting, double-rod compact cylinder featuring a 80 mm bore and 20 mm stroke. Because the piston rod exits both ends, the annular area remains identical in both chambers, yielding exactly 2267.8 N of force at 0.5 MPa whether extending or retracting. This symmetric output is perfect for balanced actuation tasks.
A built-in magnet (-S) enables position detection via AirTAC reed or electronic switches fitted into the body grooves. The short riveted body minimizes axial footprint, while end-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X20S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X20S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 20 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 SDAD80X20S Is Used
Web Guiding Mechanism
Utilizes the anti-rotation through-rod to steer material evenly, maintaining precise alignment without twisting under the 2267.8 N symmetric load.
Balanced Lift Station
Lifts platforms vertically with identical push and pull force, safely handling loads up to 115.6 kg with a 2:1 margin during transit.
Dual-End Transfer Unit
Mounts a grip on the first rod end and a position dog on the opposite end, allowing simultaneous actuation and sensor feedback in tight spaces.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X20S the Right Cylinder?
When sizing this unit, compare its 2267.8 N @0.5 MPa capacity against neighboring bores: the SDAD63 provides 1401.5 N, and the SDAD100 offers 3524.9 N. This model provides a safe working load of roughly 1361 N (about 60% of the 0.5 MPa figure) and can vertically lift approximately 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and permits driving a tool on one end with a dog on the opposite side. Remember that a standard cylinder drifts when air is removed or the valve centers; utilize an external rod lock or pilot-operated check valve for load holding. This configuration includes the S magnet, female M14x1.5 rod threads, and a PT3/8 port.
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 SDAD80X20S FAQ
The push and pull forces are equal at 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 double-rod design resists rotation and allows tool mounting on one end while using the other for a dog. The built-in S magnet supports reed or electronic switches for position feedback.
