Airtac SDAD Double Rod Slim Cylinder SDAD40X100
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X100 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 100mm 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 SDAD40X100
The AirTAC SDAD40X100 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, giving exactly 527.8 N of force at 0.5 MPa in each direction. This symmetry is ideal for driving loads that require consistent momentum without twisting.
It uses a 16 mm piston rod and PT1/8 ports. The short body design drastically reduces axial mounting depth compared to standard round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This SKU ships without a piston magnet, so it cannot directly host magnetic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD40X100 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X100 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 100 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 SDAD40X100 Is Used
Symmetric Ejector
Pushes a part out on the extend stroke and retracts a latch with the same 527.8 N force, ensuring consistent ejection timing on both ends.
Anti-Twist Lift
Raises a guided platform using the dual-end rod to prevent rotation during vertical transfer over the 100 mm travel distance.
Dual-End Transfer
Drives a primary gripper on one side while mounting a mechanical dog on the opposite rod end for external cam tracking.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X100 the Right Cylinder?
When sizing this 40 mm bore, consider the SDAD32 which yields 345.6 N at 0.5 MPa, or step up to the SDAD50 providing 824.7 N at 0.5 MPa. The 100 mm stroke on this unit sits comfortably within the 130 mm standard maximum. The through-rod geometry resists rotation and lets you mount a secondary tool or dog on the opposite end.
This configuration has female M8x1.25 rod-end threads and no magnet. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed NBR bumper only decelerates near the stroke end and acts purely as a bumper, never as a lock or brake. For load holding 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 SDAD40X100 FAQ
The double-rod design provides equal force in both directions: 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.
No, this specific SKU lacks the built-in piston magnet. You would need the SDAD40X100S variant to use reed or electronic switches for position sensing.
