Airtac SDAD Double Rod Slim Cylinder SDAD63X5B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X5B 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 SDAD63X5B
The AirTAC SDAD63X5B is a compact double-acting cylinder featuring a 63mm bore and a 5mm stroke, engineered with twin rods exiting both ends of its riveted body. Because the piston 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 a major advantage for loads requiring balanced actuation without drift bias.
Designed for minimal axial mounting depth, this short body saves valuable space in tight machinery. The through-rod geometry inherently resists twisting, allowing you to drive a tool on one end while mounting a secondary mechanism on the opposite side. This specific SKU includes male M18x1.5 threads on both rod ends and lacks a piston magnet, meaning it cannot directly host magnetic switches without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD63X5B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X5B |
|---|---|
| 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 SDAD63X5B Is Used
Short-Stroke Gripper Actuation
Uses the 5mm stroke and equal 1401.5 N force to rapidly open and close heavy-duty machining grippers without rotational deflection.
Symmetric Lift Stations
Lifts approximately 71.4 kg of vertical load with a 2:1 margin, leveraging the twin male M18x1.5 rods for balanced dual-end tooling attachment.
Anti-Twist Pressing Jig
Presses small components with high precision, relying on the through-rod geometry to prevent twisting during the brief 5mm travel.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X5B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD50 provides 824.7 N at 0.5 MPa, while moving up to the SDAD80 offers 2267.8 N. The 63mm bore hits a versatile middle ground, providing a safe working load of roughly 841 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin. The twin-rod design ensures high anti-rotation stability for rigid tooling.
This configuration features a 5mm stroke, a PT1/4 air port, and male M18x1.5 rod threads on both ends. Remember that a standard cylinder does not hold position upon air loss or valve centering; the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. End-of-stroke deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
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 SDAD63X5B FAQ
The double-rod design provides equal force in both directions: 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 have a piston magnet, so it cannot host reed or electronic switches. You would need the -S variant for sensing. However, the dual male M18x1.5 rod ends allow mounting a mechanical dog or external sensor on the opposite side from your tool.
