Airtac SDAD Double Rod Slim Cylinder SDAD63X45B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X45B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 45mm 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 SDAD63X45B
The AirTAC SDAD63X45B is a compact double-acting 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 symmetric thrust is ideal for opposing workstations or synchronized clamping tasks.
Equipped with male M18x1.5 rod threads on both ends, this 63 mm bore unit saves axial mounting depth compared to standard profile bodies. The integrated through-rod inherently resists mechanical twisting during operation. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, keeping the overall envelope short.
Airtac SDAD Double Rod Slim Cylinder SDAD63X45B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X45B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 45 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 SDAD63X45B Is Used
Dual-Station Transfer
Drives two opposing tooling plates simultaneously with equal 1401.5 N force, utilizing the through-rod geometry to push and pull mirrored assemblies.
Anti-Rotation Guiding
Handles a 71.4 kg vertical lift where the twin rods prevent mechanical twisting during heavy clamping, ensuring precise vertical alignment without side play.
Shallow Enclosure Actuation
Fits into tight machine frames where axial depth is restricted, using the compact riveted body and male M18x1.5 rod ends to mount tooling directly.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X45B the Right Cylinder?
When sizing this model, consider the neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 yields 2267.8 N at 0.5 MPa. The 63 mm bore sits perfectly in between, offering a safe working load of roughly 841 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin.
This specific SKU includes male M18x1.5 piston rod threads and lacks a piston magnet, so position sensing is not supported without the -S variant. Remember that a standard double-rod cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. For secure load holding, install an external rod lock or 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 SDAD63X45B 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 with a proof pressure of 1.5 MPa.
Yes, the through-rod design allows you to drive a load on one end while using the opposite end for a dog or secondary mechanism. However, this specific SKU lacks a piston magnet, so it cannot support magnetic switches unless you select the -S variant for reed or electronic sensing.
