Airtac SDAD Double Rod Slim Cylinder SDAD63X25
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X25 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 25mm 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 SDAD63X25
The AirTAC SDAD63X25 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 an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetry is ideal for moving loads without inducing bias or twist.
With a 63 mm bore and 25 mm stroke, this unit uses a 20 mm rod and PT1/4 port. The short body design minimizes axial mounting depth where space is tight. End-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion, making it suitable for moderate cycling speeds up to 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD63X25 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X25 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 25 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 SDAD63X25 Is Used
Gripper Synchronization
Drives a dual-jaw gripper where the 1401.5 N equal force ensures both jaws clamp with identical pressure, preventing part deformation.
Elevator Stage
Lifts a 71.4 kg vertical platform using the 2:1 safety margin, relying on the through-rod to prevent platform twist during ascent.
Dual-End Transfer
Pushes a part forward with one rod end while the opposite end simultaneously retracts a return dog, maximizing cycle efficiency.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X25 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. This SDAD63X25 strikes a middle ground, offering a safe working load of roughly 841 N, which translates to a vertical lift capacity of about 71.4 kg with a 2:1 safety margin.
The through-rod geometry resists rotation and allows mounting a tool on one end while a dog rides on the opposite end. This specific SKU lacks a piston magnet, so position sensing is not possible without the -S variant. Note that a standard cylinder drifts when air is removed or a 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 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 SDAD63X25 FAQ
The push and pull forces are equal at 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The theoretical maximum force is 286 kgf at 1.0 MPa in both directions.
No, this specific SKU does not have a piston magnet. You must select the -S option to add a magnet for AirTAC reed or electronic switches.
