Airtac SDAD Double Rod Slim Cylinder SDAD40X130S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X130S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 130mm 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 SDAD40X130S
The AirTAC SDAD40X130S 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 527.8 N of push and pull force at 0.5 MPa. This symmetric thrust is ideal for balancing loads without tweaking pressure.
The built-in magnet supports AirTAC reed or electronic switches for end-position sensing. With a 16 mm rod diameter and a 130 mm stroke, the fixed NBR bumpers decelerate the piston at stroke ends. The short body depth saves axial space while the dual-end geometry resists twisting, letting you mount a tool on one side and a sensor dog on the other.
Airtac SDAD Double Rod Slim Cylinder SDAD40X130S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X130S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 130 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/8 |
| Rod end thread | M8×1.25 female / M14×1.5 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 (Ø40mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 SDAD40X130S Is Used
Web Guiding Mechanism
Uses the dual-end through-rod to mount a guiding roller on one side and a position flag on the other, relying on equal 527.8 N force to prevent film deflection.
Transfer Shuttle
Pushes and pulls a conveyor cart between stations with identical thrust in both directions, ensuring consistent cycle times regardless of travel orientation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X130S the Right Cylinder?
When sizing this unit, compare its 527.8 N output at 0.5 MPa against its neighbors. Dropping to the SDAD32 yields 345.6 N, whereas stepping up to the SDAD50 provides 824.7 N.
The through-rod prevents rotation and enables dual-end mounting. Remember that a plain cylinder drifts if air is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. This configuration includes the S magnet and female M8x1.25 rod threads on both ends, with a PT1/8 port.
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 SDAD40X130S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa in both directions.
Yes, the through-rod exits both ends, allowing you to drive a tool on one side while mounting a dog for a reed or electronic switch on the other. The S option indicates the piston magnet is already included for position sensing.
