Airtac SDAD Double Rod Slim Cylinder SDAD63X45S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X45S 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 SDAD63X45S
The AirTAC SDAD63X45S is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for driving loads that require consistent resistance without twisting.
This 63 mm bore unit saves axial mounting depth compared to standard profile bodies. It includes a built-in piston magnet for position sensing and relies on a fixed NBR bumper at each end to decelerate the stroke. The 20 mm diameter rods provide rigid anti-rotation support, while the PT1/4 port manages the air supply.
Airtac SDAD Double Rod Slim Cylinder SDAD63X45S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X45S |
|---|---|
| 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 SDAD63X45S Is Used
Web Guiding Mechanism
Utilizes the equal 1401.5 N force in both directions to tension and steer material rolls without deflection, while the dual-end rods resist twisting during high-speed tracking.
Symmetric Lift Station
Raises and lowers a 71.4 kg platen using the through-rod design, allowing a position dog to trigger an electronic switch on the rear end while the front end drives the load.
Dual-Side Clamping Jig
Deploys a gripping tool on one rod end and a mechanical stop on the other, taking advantage of the compact riveted body to fit within tight machine frames.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X45S the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to the SDAD50 yields 824.7 N at 0.5 MPa, while stepping up to the SDAD80 provides 2267.8 N. The SDAD63X45S sits comfortably in the middle, offering a computed safe working load of roughly 841 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin.
The through-rod geometry prevents rotation and permits mounting a tool on one end with a dog or switch on the opposite side. This configuration includes the S option for an AirTAC reed or electronic switch. Remember that a plain cylinder drifts when air is lost or the valve centers; use an external rod lock or pilot-operated check valve for strict load holding. Rod-end threads are female M10x1.5 or male M18x1.5.
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 SDAD63X45S FAQ
The push and pull forces are equal because the rod exits both ends. It 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. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod resists rotation and protrudes from both sides, allowing you to drive a workpiece on one end while mounting a dog to trigger the built-in magnet with an AirTAC reed or electronic switch on the opposite end.
