Airtac SDAD Double Rod Slim Cylinder SDAD80X85S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X85S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 85mm 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 SDAD80X85S
The AirTAC SDAD80X85S 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, delivering an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetric output is highly advantageous for moving balanced loads without shifting the center of gravity.
The 25 mm piston rod resists twisting during operation and allows you to drive a tool on one end while mounting a dog or switch on the opposite side. Fitted with a built-in magnet, this unit supports AirTAC reed or electronic switches for position sensing. The short body design saves axial mounting depth, and end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X85S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X85S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 85 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 SDAD80X85S Is Used
Precision Lift Stations
Lifts symmetric platens using the equal 2267.8 N force both ways, ensuring the platform remains level without twisting during vertical transfer.
Dual-End Transfer Carriage
Drives a workpiece gripper on the front rod while a position dog rides the rear rod, leveraging the 25 mm through-rod for stable, anti-rotation movement.
Heavy Duty Ejector
Ejects dense parts from a press using the 115.6 kg vertical lift capacity, relying on the fixed NBR bumper to absorb the end-of-stroke shock.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X85S the Right Cylinder?
When sizing this model, compare it with its neighbors. Dropping down to the SDAD63 yields 1401.5 N at 0.5 MPa, whereas stepping up to the SDAD100 provides 3524.9 N at 0.5 MPa. Based on the 2267.8 N output at 0.5 MPa, the computed safe working load is approximately 1361 N (using a 60% margin), which translates to a vertical lift capacity of about 115.6 kg with a 2:1 safety factor.
The through-rod geometry provides excellent anti-rotation stability and dual-end mounting flexibility. Remember that a standard cylinder cannot hold a load if air pressure is lost or the valve is centered; the piston will drift and the fixed NBR bumper only decelerates near the stroke end. For secure load holding, integrate an external rod lock or a pilot-operated check valve. This configuration includes the S magnet option, a PT3/8 port, and female M14x1.5 rod-end threads on both sides.
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 SDAD80X85S 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 force is 463 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
Yes, the 25 mm through-rod exits both ends, allowing you to mount a tool on one side and a dog for a reed or electronic switch on the other. The built-in magnet enables position sensing, while the through-rod inherently resists twisting.
