Airtac SDAD Double Rod Slim Cylinder SDAD40X110B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X110B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm 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 SDAD40X110B
The AirTAC SDAD40X110B 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 force at 0.5 MPa in each direction. This symmetric output is ideal for balanced tooling.
This specific SKU uses male M14x1.5 thread on the 16 mm rods at both ends. The short body design saves axial mounting depth compared to standard round-body units. End-of-stroke deceleration is handled by a fixed NBR bumper, and the unit operates at speeds between 30 and 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD40X110B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X110B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 110 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 SDAD40X110B Is Used
Symmetric Gauging Station
Uses the equal 527.8 N push and pull force to clamp a part on one end while a gauge checks dimensions on the opposite rod end.
Dual-Side Transfer Arm
Exploits the anti-rotation through-rod to push a product left, then pull it right with identical 0.5 MPa force without twisting.
Vertical Lift Jig
Lifts a 26.9 kg jig vertically using the male M14x1.5 threaded rods, relying on the compact body to fit tight vertical spaces.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X110B the Right Cylinder?
When sizing this actuator, the adjacent SDAD32 provides 345.6 N at 0.5 MPa, while stepping up to the SDAD50 yields 824.7 N. The through-rod geometry prevents twisting and lets you mount a tool on one end while driving a dog on the opposite side.
This configuration includes the male M14x1.5 rod threads and a 110 mm stroke, utilizing a PT1/8 port. Note that this SKU lacks the S magnet, so position sensing is not supported. Furthermore, the fixed bumper only decelerates the stroke end; the cylinder will drift and cannot hold a load on air loss or valve centering without 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 SDAD40X110B FAQ
The double-rod design provides equal force in both directions: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. The theoretical maximum is 108 kgf at 1.0 MPa.
Yes, the through-rod exits both sides with male M14x1.5 threads, allowing you to drive a tool on one end and mount a dog on the other while the rod resists rotational twist.
