Airtac SDAD Double Rod Slim Cylinder SDAD50X35
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X35 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 SDAD50X35
The AirTAC SDAD50X35 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 on extend and retract, delivering an equal 824.7 N of push and pull force at 0.5 MPa. This symmetry is essential for mechanisms requiring consistent kinetic output regardless of travel direction.
A 20 mm piston rod on each end provides high torsional rigidity to resist twisting during heavy lateral loads. The short body design minimizes axial mounting depth compared to conventional round-body units. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, and this specific SKU lacks a piston magnet, so it cannot directly host position switches.
Airtac SDAD Double Rod Slim Cylinder SDAD50X35 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X35 |
|---|---|
| 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 SDAD50X35 Is Used
Symmetric Transfer Chuck
Equal 824.7 N force in both directions ensures a clamping chuck applies identical pressure when opening and closing, preventing part deformation.
Dual-End Lift Jig
The through-rod allows a lift jig to be driven from the bottom while a tracking dog mounts on the top, maintaining anti-rotation stability for 42 kg vertical lifts.
Compact Carton Flap Folder
Short riveted body depth saves valuable axial space on a tight packaging line while providing the 1154.5 N force needed at 0.7 MPa to fold heavy corrugated flaps.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X35 the Right Cylinder?
When sizing this 50 mm bore model, consider the adjacent options in the series. Dropping down to the SDAD40 yields 527.8 N at 0.5 MPa, whereas stepping up to the SDAD63 provides 1401.5 N. This SDAD50X35 strikes a middle ground, offering a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa rating) and a vertical lift capacity near 42 kg with a 2:1 safety margin.
The through-rod geometry allows you to mount a work tool on one end and a mechanical dog on the opposite end simultaneously. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates the stroke end and does not function as a lock. For suspended loads, integrate an external pilot-operated check valve. This configuration features a 35 mm stroke, PT1/4 port, and female M10x1.5 rod-end threads 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 SDAD50X35 FAQ
The SDAD50X35 delivers equal force in both directions due to its double-rod design. It outputs 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.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the SDAD50X35S variant for position sensing. However, the dual-end through-rod still allows you to mount an external mechanical dog to trigger external sensors.
