Airtac SDAD Double Rod Slim Cylinder SDAD50X35B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X35B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 35mm 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 SDAD50X35B
The AirTAC SDAD50X35B is a double-acting compact 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, delivering an equal push and pull force of 824.7 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic energy regardless of travel direction.
This specific SKU includes male M18x1.5 piston rod threads on both ends and a 20 mm rod diameter. It lacks a piston magnet, so it cannot directly host reed or electronic switches without the -S option. The short body design minimizes axial footprint, while the fixed NBR bumpers absorb end-of-stroke impacts within the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD50X35B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X35B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 35 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 SDAD50X35B Is Used
Symmetric Transfer Clamps
Drives clamping jaws that push and pull equal 824.7 N loads at 0.5 MPa, ensuring consistent grip force during component transfer.
Anti-Rotation Lift Stations
Lifts 42 kg vertical payloads using the through-rod to resist twist, preventing platform binding without external linear guides.
Dual-End Sealing Presses
Mounts a sealing head on one rod end and a mechanical dog on the other, utilizing the 35 mm stroke for compact packaging operations.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X35B the Right Cylinder?
When sizing this unit, consider the neighboring bores: the SDAD40 provides 527.8 N at 0.5 MPa, while the SDAD63 offers 1401.5 N. The 50 mm bore hits a middle ground, yielding a safe working load of roughly 495 N (about 60% of the 824.7 N figure) and a vertical lift capacity near 42 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and permits mounting a tool on one end and a dog on the opposite side.
Confirm the 50 mm bore, 35 mm stroke, and PT1/4 port meet your pneumatic layout. Note that this version has male M18x1.5 rod threads. Because it lacks a magnet, position sensing is unavailable. Furthermore, the fixed NBR bumper only decelerates the stroke end; it does not hold the load. If air pressure drops, the piston will drift, requiring an external rod lock or pilot-operated check valve for secure load holding.
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 SDAD50X35B FAQ
The push and pull forces are equal because the rod exits both ends. It generates 824.7 N at 0.5 MPa, 1154.5 N at 0.7 MPa, and a theoretical maximum of 168 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not have a piston magnet, so it cannot host reed or electronic switches. You would need the -S variant for sensing. However, the dual-end male M18x1.5 rods allow you to mount a mechanical dog on the opposite end to trigger an external sensor.
