Airtac SDAD Double Rod Slim Cylinder SDAD63X80
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X80 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm 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 SDAD63X80
The AirTAC SDAD63X80 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, yielding exactly 1401.5 N of force at 0.5 MPa on both the extend and retract strokes. This symmetric output is ideal for loads requiring balanced push and pull.
A 20 mm piston rod resists mechanical twisting during operation. The short body design minimizes axial footprint compared to standard round-body units. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot directly host reed or electronic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD63X80 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X80 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 80 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SDAD63X80 Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm requiring identical 1401.5 N push and pull force to smoothly shuttle components between stations without twisting.
Dual-End Lifters
Utilizes the through-rod to elevate a platform on one end while a mechanical dog triggers an external limit switch on the opposite side.
Anti-Rotation Guiding
Handles straightening duties where the 20 mm twin rods prevent torsional deflection across the 80 mm stroke in tight assembly fixtures.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X80 the Right Cylinder?
When sizing this unit, verify if the 1401.5 N output at 0.5 MPa fits your dynamic requirements. Stepping down, the SDAD50 provides 824.7 N, while stepping up to the SDAD80 yields 2267.8 N. For this 63 mm bore, the air port is PT1/4, and the female rod-end thread is M10x1.5. The 80 mm stroke falls within the 130 mm standard limit.
The dual-end geometry allows driving a tool on one side while mounting a mechanical dog on the opposite end. Keep in mind that a plain cylinder drifts when air pressure is lost or the valve centers, as the NBR bumper only decelerates near the stroke end and acts purely as a bumper, never a lock. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
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 SDAD63X80 FAQ
The push and pull forces are equal because the rod exits both ends. It generates 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The theoretical maximum is 286 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet. You must select the -S option variant to enable sensing with AirTAC reed or electronic switches. The through-rod design still allows you to mount a mechanical dog on the unused end for external position tracking.
