Airtac SDAD Double Rod Slim Cylinder SDAD63X5
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X5 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 5mm 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 SDAD63X5
The AirTAC SDAD63X5 is a compact double-acting pneumatic cylinder featuring a through-rod that exits both ends of its riveted body. Because the rod occupies both chambers, the annular area remains identical in each direction, yielding equal push and pull forces of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for balancing loads during short clamping or ejecting tasks.
With a mere 5 mm stroke, this model provides immediate motion in extremely shallow mounting envelopes. The 20 mm diameter rod enhances structural rigidity against twisting, while the fixed NBR bumpers absorb end-of-stroke impact. Note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD63X5 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X5 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 5 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 SDAD63X5 Is Used
Short-Stroke Clamping
Applies 1401.5 N of symmetric holding force to secure heavy machined parts during milling without shifting the centre of gravity.
Anti-Rotation Ejector
Uses the twin 20 mm rods to resist twisting while ejecting dense metal components from a die in a confined 5 mm space.
Dual-End Transfer
Drives a pusher plate on the front stroke while the opposing rod end moves a mechanical flag for a hard-stop limit setup.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X5 the Right Cylinder?
When sizing this unit, consider the neighbouring bores: the SDAD50 provides 824.7 N at 0.5 MPa, whereas the larger SDAD80 offers 2267.8 N at 0.5 MPa. This 63 mm bore sits perfectly in between, delivering a safe working load of roughly 841 N (about 60 percent of the 0.5 MPa rating) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin.
The dual-end geometry prevents rotation and permits driving a tool on one side while mounting a mechanical dog on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve centres; add an external rod lock or pilot-operated check valve for secure load holding. This configuration uses a PT1/4 port, female M10x1.5 rod threads, and operates at 30-500 mm/s.
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 SDAD63X5 FAQ
The push and pull forces are equal because the rod exits both ends. It generates 1401.5 N at 0.5 MPa, 1962.2 N at 0.7 MPa, and a theoretical maximum of 286 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet. You must select the -S option variant to use AirTAC reed or electronic solid-state switches in the body sensor grooves.
