Airtac SDAD Double Rod Slim Cylinder SDAD100X45B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X45B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 45mm 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 SDAD100X45B
The AirTAC SDAD100X45B is a double-acting, double-rod compact cylinder featuring a 100mm bore and 45mm stroke. Because the piston rod exits both ends, the annular area remains identical in each chamber, ensuring push force equals pull force at 3524.9 N for 0.5 MPa. This symmetric thrust is crucial for heavy-duty handling where loading must stay balanced.
This specific SKU includes male M26x1.5 rod threads on both ends and uses a PT3/8 air port. The through-rod geometry inherently resists twisting during operation. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, and the short riveted body conserves axial mounting depth in tight machinery setups.
Airtac SDAD Double Rod Slim Cylinder SDAD100X45B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X45B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 45 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M18×1.5 female / M26×1.5 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 (Ø100mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 3525 N |
| 0.7 MPa | 4935 N |
| Max (@1.0 MPa) | 719 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 SDAD100X45B Is Used
Heavy Press Tooling
Drives a forming die from one rod end while the opposite end synchronizes an ejection mechanism, utilizing the 3524.9 N equal bidirectional thrust.
Balanced Vertical Lifter
Lifts approximately 179.7 kg of material in a vertical gantry, relying on the through-rod to prevent twist and maintain smooth guidance under heavy loads.
Dual-End Transfer Unit
Pushes a heavy pallet from one side while a mechanical dog on the opposite rod end triggers a physical limit switch at the 45mm stroke endpoint.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X45B the Right Cylinder?
When sizing this unit, consider the adjacent bore options. Stepping down, the SDAD80 provides 2267.8 N at 0.5 MPa, which may be insufficient for heavy loads. Stepping up is not possible as 100mm is the largest available bore in this series, making the SDAD100X45B the maximum force choice at 4934.8 N for 0.7 MPa. Based on the 0.5 MPa rating, a safe working load is approximately 2115 N, allowing a vertical lift of roughly 179.7 kg with a 2:1 safety margin.
The dual-end male M26x1.5 threads allow driving a tool on one side while mounting a mechanical dog on the opposite end. Remember that a standard cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Note that this configuration lacks the -S magnet, so magnetic switches cannot be used.
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 SDAD100X45B FAQ
The push and pull forces are equal because of the double-rod design. It generates 3524.9 N at 0.5 MPa, 4934.8 N at 0.7 MPa, and a theoretical maximum of 719 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept reed or electronic switches. Additionally, end cushioning is provided by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion. For high kinetic energy, add an external shock absorber.
