Airtac SDAD Double Rod Slim Cylinder SDAD63X40B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X40B 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 SDAD63X40B
The AirTAC SDAD63X40B is a double-acting compact 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, giving you exactly 1401.5 N of push and pull force at 0.5 MPa. This symmetry prevents twisting during operation and allows tooling on one end with a dog or secondary mechanism on the opposite end.
This specific SKU includes male M18x1.5 threads on both 20 mm rod ends, paired with a PT1/4 air port. The short body design saves axial mounting depth compared to standard profile cylinders. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable cushions. Note that this variant lacks a piston magnet, so position sensing is not supported without switching to an -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD63X40B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X40B |
|---|---|
| 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 SDAD63X40B Is Used
Symmetric Lift Stations
Drives vertical lifting arms where equal 1401.5 N push and pull forces prevent sagging on the return stroke.
Dual-End Transfer
Mounts a grip on the front male M18x1.5 rod end while the rear end pushes a secondary diverter simultaneously.
Anti-Rotation Guiding
Handles straightening tasks where the through-rod resists twisting under offset loads without external guides.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X40B the Right Cylinder?
When sizing this 63 mm bore model, consider the SDAD50 which provides 824.7 N at 0.5 MPa, or step up to the SDAD80 yielding 2267.8 N at 0.5 MPa. The SDAD63X40B provides a computed safe working load of roughly 841 N, which equates to a vertical lift capacity of about 71.4 kg when applying a 2:1 safety margin. The through-rod geometry ensures high resistance to torsional loads, making it highly effective for guided mechanisms.
Keep in mind that a standard double-acting cylinder does not hold position if air pressure drops or the valve centers; the piston will drift. For load-holding requirements, install an external rod lock or pilot-operated check valve. This configuration specifies a 40 mm stroke, PT1/4 porting, no magnet, and male M18x1.5 rod threads on both sides.
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 SDAD63X40B FAQ
Because it is a double-rod cylinder, the force is identical 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.
Yes, the through-rod design exits both ends with male M18x1.5 threads, allowing you to drive a tool on one side while using the opposite side for a dog or secondary mechanism. The rod also resists rotation.
