Airtac SDAD Double Rod Slim Cylinder SDAD63X15B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X15B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 15mm 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 SDAD63X15B
The AirTAC SDAD63X15B is a compact double-acting cylinder featuring a 63mm bore and a 15mm stroke, engineered with twin piston rods exiting from both ends of its riveted body. Because a rod occupies each working chamber, the annular area remains identical in both directions, ensuring push and pull forces match exactly at 1401.5 N under 0.5 MPa. This symmetric thrust is vital for applications requiring stable, balanced motion without drift.
This specific configuration includes male M18x1.5 threads on the 20mm diameter rods at both ends, allowing direct mounting of tooling on one side and a dog or mechanism on the opposite side. The through-rod geometry inherently resists twisting, while the short body profile saves valuable axial space. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable air cushions.
Airtac SDAD Double Rod Slim Cylinder SDAD63X15B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X15B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 15 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 SDAD63X15B Is Used
Symmetric Ejector Mechanism
Drives a part ejector on one end while the opposite rod moves a dog, utilizing the equal 1401.5 N push and pull force to prevent binding during rapid ejection.
Balanced Vertical Lift
Lifts loads up to 71.4 kg with a 2:1 safety margin, where the twin 20mm rods resist twisting and maintain stable vertical guidance without side play.
Dual-End Transfer Arm
Mounts a grip tool on one male M18x1.5 end and a counterweight on the other, taking advantage of the compact riveted body to fit tight transfer stations.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X15B the Right Cylinder?
When sizing this model, compare its 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 figure, the SDAD63X15B yields a safe working load of approximately 841 N (60 percent capacity) and can vertically lift around 71.4 kg with a 2:1 safety margin. If your application requires position feedback, note this SKU lacks a piston magnet; you must specify the -S option for AirTAC reed or electronic switches.
The male M18x1.5 rod ends on both sides provide flexible dual-end mounting, but remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers—the piston will drift. For load-holding security, integrate an external rod lock or pilot-operated check valve. Ensure your layout accommodates the 20mm rods protruding from both ends to prevent mechanical interference.
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 SDAD63X15B FAQ
The SDAD63X15B 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. Because it is a double-rod cylinder, the push and pull forces are exactly equal in both directions. The maximum operating pressure is 1.0 MPa.
Yes, the male M18x1.5 threads on both rod ends allow you to mount tooling on one side and a dog or secondary mechanism on the other. However, this specific SKU does not include a piston magnet, so it cannot support magnetic switches; you would need the -S variant for reed or electronic sensing.
