Airtac SDAD Double Rod Slim Cylinder SDAD63X30
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X30 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 30mm 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 SDAD63X30
The AirTAC SDAD63X30 is a compact double-acting cylinder featuring a piston rod protruding from both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding exactly 1401.5 N of push and pull force at 0.5 MPa. This symmetry is essential for mechanisms requiring consistent kinetic output in both directions.
The 20 mm through-rod inherently resists mechanical twist, allowing you to mount a work tool on one end and a dog or switch on the opposite end simultaneously. Operating at 30-500 mm/s, the unit relies on a fixed NBR bumper at each end to decelerate the stroke. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD63X30 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X30 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 30 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 SDAD63X30 Is Used
Gripper Synchronization
Drives opposing gripper jaws where the equal 1401.5 N extend and retract forces prevent asymmetric twisting of delicate sheet metal panels.
Elevator Counterbalance
Moves a 71.4 kg vertical lift platform smoothly, using the dual-end rods to mount a cam on the rear while the front drives the load.
Transfer Shuttle
Shifts a transfer carriage between two stations, relying on the fixed NBR bumpers to absorb end-of-stroke shock at high cycle rates.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X30 the Right Cylinder?
When sizing this 63 mm bore, compare its 1401.5 N @0.5 MPa output against adjacent models. Dropping down to the SDAD50 provides 824.7 N, while stepping up to the SDAD80 yields 2267.8 N. Factoring a 2:1 safety margin, this unit safely handles a vertical lift of roughly 71.4 kg, or a safe working load around 841 N. Choose the 63 mm bore when your application demands that middle-ground thrust.
The through-rod geometry provides superior anti-rotation stability and dual-end mounting flexibility. Remember that a plain SDAD does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration uses a PT1/4 port, female M10x1.5 rod threads, and a 30 mm stroke within the 130 mm standard limit.
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 SDAD63X30 FAQ
The double-rod design provides equal force 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. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the SDAD63X30S variant. The through-rod does allow you to mount a physical dog or external sensor on the opposite end.
