Airtac SDAD Double Rod Slim Cylinder SDAD80X20SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X20SB 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 SDAD80X20SB
The AirTAC SDAD80X20SB 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 push and pull force at 0.5 MPa. This symmetric output is ideal for balanced actuation tasks.
This specific configuration includes a built-in piston magnet for position sensing and male M22x1.5 rod threads on both ends. The short body design minimizes axial mounting depth, while the fixed NBR bumpers absorb end-of-stroke shock. Operating pressure spans 0.15 to 1.0 MPa, and the piston speed ranges from 30 to 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD80X20SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X20SB |
|---|---|
| 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 SDAD80X20SB Is Used
Web Guide Mechanism
Uses the anti-rotation through-rod to steer material evenly, maintaining precise tracking without twisting under the 2267.8 N bidirectional load.
Lifting Platform Stop
Drives a rigid stop on one rod end while mounting a proximity dog on the opposite side, leveraging the equal push and pull force for stable vertical halts.
Symmetric Clamping Jig
Clamps parts from both directions simultaneously using the dual male M22x1.5 rod ends, ensuring perfectly balanced pressure during machining.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X20SB the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD63 provides 1401.5 N at 0.5 MPa, while moving up to the SDAD100 offers 3524.9 N. The 80 mm bore hits a strong middle ground, offering a safe working load of roughly 1361 N or a vertical lift capacity of about 115.6 kg with a 2:1 margin.
The through-rod geometry resists twisting and permits mounting a tool on one end with a dog or switch on the opposite side. Note that a plain cylinder drifts when air is lost or the valve is centered, as the fixed bumper only decelerates near stroke end; use an external rod lock or pilot-operated check valve for load holding. This model is confirmed with a 20 mm stroke, PT3/8 port, an S magnet for reed or electronic switches, and B male-thread rods.
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 SDAD80X20SB FAQ
The force is equal in both directions due to the double-rod design: 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod exits both ends, allowing you to drive a tool on one side while mounting a dog for a reed or electronic switch on the opposite side. The built-in S magnet enables this position sensing.
