Airtac SDAD Double Rod Slim Cylinder SDAD50X30
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X30 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm 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 SDAD50X30
The AirTAC SDAD50X30 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 on extend and retract, yielding exactly 824.7 N of force at 0.5 MPa in each direction. This symmetric output is essential for mechanisms requiring balanced push and pull dynamics.
A 20 mm piston rod resists twisting during traversal, while the short body footprint minimizes axial mounting depth compared to standard profile cylinders. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston rather than acting as an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot directly host magnetic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD50X30 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X30 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X30 Is Used
Gripper Jaw Synchronization
Drives opposing gripper arms with equal 824.7 N push and pull forces, ensuring centered clamping on heavy billets without rotational deflection.
Elevator Counterbalance
Uses the dual-end through-rod to lift a 42 kg vertical payload while simultaneously triggering a mechanical dog on the opposite side.
Transfer Shuttle Alignment
Shifts a transfer carriage between stations, leveraging the anti-twist geometry to keep the tooling plate perfectly parallel during rapid 30 mm shifts.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X30 the Right Cylinder?
When sizing this 50 mm bore, consider the adjacent options. Dropping down to the SDAD40 provides 527.8 N at 0.5 MPa, whereas stepping up to the SDAD63 yields 1401.5 N at 0.5 MPa. For the SDAD50X30, a safe working load is approximately 495 N, or a vertical lift of roughly 42 kg with a 2:1 safety margin. This model features a 30 mm stroke, a PT1/4 air port, and female M10x1.5 rod-end threads on both ends.
The through-rod design inherently resists rotation and allows mounting a tool on one end with a dog on the opposite side. Remember that a standard cylinder drifts when air is removed or the valve is centered; the fixed NBR bumper only decelerates near the stroke end and will not hold the load. For secure load holding without live pressure, integrate 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 SDAD50X30 FAQ
The push and pull forces are identical due to the double-rod design. It generates 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the SDAD50X30S variant for internal magnetic sensing, though you can still mount external mechanical dogs on the exposed rod.
