Airtac SDAD Double Rod Slim Cylinder SDAD63X40S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X40S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 40mm 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 SDAD63X40S
The AirTAC SDAD63X40S is a compact double-acting cylinder featuring a 63mm bore and 40mm stroke, engineered with twin piston rods exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area remains identical in both directions, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for balanced actuation, while the through-rod geometry inherently resists mechanical twisting during operation.
Designed to save axial mounting depth, this thin profile fits where larger profile cylinders cannot. The integrated -S piston magnet supports position detection via reed or electronic switches. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston near stroke end rather than acting as an adjustable air cushion or a locking brake.
Airtac SDAD Double Rod Slim Cylinder SDAD63X40S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X40S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 40 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 SDAD63X40S Is Used
Symmetric Transfer Gates
Drives dual-sided gating mechanisms where the equal 1401.5 N extend and retract forces prevent linkage binding during high-speed part diversion.
Balanced Lift Stations
Lifts 71.4 kg vertical loads using the through-rod design to mount a primary tool on one end and a position dog on the opposite end simultaneously.
Anti-Rotation Clamping
Holds workpieces securely in machining fixtures, relying on the twin rods to resist twisting moments that would skew a single-rod actuator.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X40S the Right Cylinder?
When sizing this unit, compare its bidirectional 1401.5 N output at 0.5 MPa against adjacent bores: the SDAD50 provides 824.7 N, while the SDAD80 offers 2267.8 N. Based on the 0.5 MPa rating, a safe working load is approximately 841 N (60 percent capacity), translating to a vertical lift capability of roughly 71.4 kg with a 2:1 safety margin. The through-rod allows driving a tool on one end while mounting a dog or switch on the opposite end without twisting.
This configuration features a 20mm rod diameter, female M10x1.5 rod-end threads, and a PT1/4 port. It includes the -S magnet for sensing. Remember that a plain cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end. For secure 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 SDAD63X40S FAQ
The double-rod design provides equal force in both directions: 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.
Yes, the through-rod extends from both ends, allowing you to drive a tool on one side and mount a reed or electronic switch on the other. The included -S magnet enables this position sensing.
