Airtac SDAD Double Rod Slim Cylinder SDAD63X80S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X80S 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 SDAD63X80S
The AirTAC SDAD63X80S is a compact double-acting 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 1401.5 N at 0.5 MPa. This symmetry is highly advantageous for loads requiring consistent kinetic behavior without sudden acceleration changes.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The 63 mm bore utilizes a 20 mm rod and a PT1/4 port, operating at speeds between 30-500 mm/s. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston rather than acting as a lock or adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X80S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X80S |
|---|---|
| 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 SDAD63X80S Is Used
Symmetric Transfer Gates
Drives dual-action gating where the 1401.5 N equal force ensures smooth, balanced material routing without twist, utilizing the 80 mm stroke for rapid open-close cycles.
Balanced Vertical Lifts
Lifts loads up to 71.4 kg with a 2:1 margin, using the through-rod to maintain anti-rotation stability while mounting a secondary guide on the opposing end.
Dual-End Forming Stations
Actuates a forming tool on one rod end while a solid-state switch tracks the opposite end, leveraging the fixed NBR bumper to absorb the 30-500 mm/s stroke impact.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X80S the Right Cylinder?
When sizing this model, compare it with neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 yields 2267.8 N at 0.5 MPa. Based on the 1401.5 N output at 0.5 MPa, the safe working load is approximately 841 N (60% capacity), translating to a vertical lift capability of roughly 71.4 kg with a 2:1 safety margin.
The through-rod design resists twisting and allows mounting a tool on one end and a sensor dog on the opposite side. Remember that a plain cylinder drifts if air pressure is lost or the valve centers; utilize an external rod lock or pilot-operated check valve for strict load holding. This configuration includes the -S magnet and standard female M10x1.5 rod-end threads on both ends.
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 SDAD63X80S FAQ
The push and pull forces are equal at 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 maximum operating pressure of 1.0 MPa and proof pressure of 1.5 MPa.
Yes, the through-rod resists rotation and allows you to drive a tool on one end while mounting a dog for a reed or electronic switch on the other. The -S magnet enables this position sensing.
