Airtac SDAD Double Rod Slim Cylinder SDAD50X110SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X110SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 110mm 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 SDAD50X110SB
The AirTAC SDAD50X110SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber, the annular area remains identical in both directions, yielding an equal push and pull force of 824.7 N at 0.5 MPa. This symmetric output is ideal for balanced actuation without differential thrust.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, the unit provides position feedback via the body sensor grooves. The -B option specifies male M18x1.5 threads on both 20 mm rod ends, while the PT1/4 port supplies filtered air. A fixed NBR bumper decelerates the stroke ends within the 30-500 mm/s speed range, and the short body depth minimizes axial footprint.
Airtac SDAD Double Rod Slim Cylinder SDAD50X110SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X110SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 110 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 SDAD50X110SB Is Used
Symmetric Transfer Chuck
Grips and shifts components with 824.7 N of equal push/pull force at 0.5 MPa, preventing skewed movement during bidirectional transfer.
Dual-End Lift Fixture
Uses the male M18x1.5 rods on both ends to elevate a 42 kg payload, maintaining vertical stability without rotational twist.
Cam Switch Trigger
Drives a machining operation on one end while the opposite side actuates a reed or electronic switch dog for precise cycle timing.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X110SB the Right Cylinder?
When sizing this 50 mm bore, compare its 824.7 N output at 0.5 MPa against adjacent models: the SDAD40 yields 527.8 N, whereas the SDAD63 provides 1401.5 N. This positions the SDAD50X110SB perfectly for medium-force duties, offering a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 42 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and permits mounting a tool on one end with a dog on the opposite side. Confirm your setup requires the 110 mm stroke, PT1/4 port, male M18x1.5 rod threads, and the -S magnet. Note that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near stroke end and will not hold the load. For secure positioning without live pressure, 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 SDAD50X110SB FAQ
The double-rod design provides equal force in both directions: 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa. The theoretical maximum is 168 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
The through-rod resists twisting and allows mounting a tool on one end and a switch dog on the other. The male M18x1.5 threads on both 20 mm rods simplify fixture attachment while maintaining identical extend and retract areas.
