Airtac SDAD Double Rod Slim Cylinder SDAD63X80B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X80B 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 SDAD63X80B
The AirTAC SDAD63X80B 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, yielding equal push and pull forces of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for balanced actuation, while the through-rod geometry inherently resists twisting during operation.
This specific configuration includes male M18x1.5 rod-end threads on both sides and a PT1/4 air port. The 80 mm stroke operates within the 130 mm standard limit, and the short body design saves axial mounting depth compared to conventional round-body units. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable air cushions.
Airtac SDAD Double Rod Slim Cylinder SDAD63X80B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X80B |
|---|---|
| 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 SDAD63X80B Is Used
Web Guiding Mechanism
Uses the male M18x1.5 threads on both ends to mount opposing guide rollers, relying on the 1401.5 N equal bidirectional force to keep material tracking centered without twist.
Symmetric Lift Station
Drives a vertical lifting plate from the bottom while the top rod end holds a counter-dog, leveraging the anti-rotation through-rod to lift 71.4 kg smoothly.
Dual-Action Transfer
Pushes a part forward on the extend stroke and retracts a secondary latch on the same cycle, taking advantage of the matched push and pull areas to synchronize motion.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X80B the Right Cylinder?
When sizing this model, consider the neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 offers 2267.8 N. The 63 mm bore hits a practical middle ground, offering a safe working load of roughly 841 N (about 60% of its 0.5 MPa rating) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin. The through-rod allows driving a tool on one end while mounting a dog or fixture on the opposite end.
This SKU lacks the -S magnet, so position sensing via reed or electronic switches is not supported without changing to the -S variant. Note that a standard cylinder does not hold position if air pressure drops or the valve is centered; the piston will drift. For load holding without live pressure, install an external rod lock or a 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 SDAD63X80B 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, with a theoretical maximum of 286 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
This specific SKU lacks the -S magnet, so it cannot accept reed or electronic switches. Additionally, the fixed NBR bumper only decelerates the stroke end; it does not act as a brake. The piston will drift if air is lost, so use an external rod lock or pilot-operated check valve for load holding.
