Airtac SDAD Double Rod Slim Cylinder SDAD20X80B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD20X80B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø20mm 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 SDAD20X80B
The AirTAC SDAD20X80B is a compact double-acting cylinder featuring a through-rod that exits both ends of its riveted body. Because the rod occupies each chamber equally, the annular area matches, giving you 131.9 N of push and pull force at 0.5 MPa. This symmetry is ideal for driving loads that require consistent effort in both directions.
Equipped with male M6x1.0 rod threads on both ends, this 20 mm bore unit simplifies dual-end tooling or dog mounting. The 80 mm stroke operates at 30-500 mm/s, relying on a fixed NBR bumper at each end to decelerate the piston. Note this SKU lacks a piston magnet, so position sensing requires the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD20X80B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD20X80B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 80 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M4×0.7 female / M6×1.0 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 90 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 (Ø20mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 132 N |
| 0.7 MPa | 185 N |
| Max (@1.0 MPa) | 27 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 SDAD20X80B Is Used
Symmetric Transfer
Drives a gripper on one end and a position dog on the other, utilizing the equal 131.9 N push and pull force for balanced part shuttling.
Anti-Rotation Guide
The dual exiting rods resist torsional twist during tight-tolerance pressing tasks where a single rod might bind.
Dual-End Tooling
Mounts a male M6x1.0 threaded fixture on each side to actuate two separate mechanisms sequentially within the 80 mm span.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD20X80B the Right Cylinder?
When sizing this unit, compare its 131.9 N @0.5 MPa output against adjacent bores: the SDAD16 yields 86.4 N, while the SDAD25 provides 206.2 N. For your 20 mm choice, a safe working load is roughly 79 N (about 60% of the 0.5 MPa figure), translating to a 6.7 kg vertical lift with a 2:1 safety margin.
The through-rod geometry prevents twisting during operation, allowing a dog or secondary tool on the opposite end. Remember that a plain cylinder drifts when air is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. This configuration specifies the 80 mm stroke, M5x0.8 port, and male M6 rod threads.
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 SDAD20X80B FAQ
The double-rod design yields equal force in both directions: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 27 kgf at 1.0 MPa.
No, this specific SKU lacks a built-in piston magnet. You must select the -S option to use AirTAC reed or electronic switches in the body sensor grooves.
