Airtac SDAD Double Rod Slim Cylinder SDAD100X40
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD100X40 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø100mm bore, 40mm 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 SDAD100X40
The AirTAC SDAD100X40 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 in each direction, giving you exactly 3524.9 N of push and pull force at 0.5 MPa. This symmetry is essential when driving rigid loads that require balanced actuation.
With a 100 mm bore and 32 mm rod, this unit uses a PT3/8 port and travels a 40 mm stroke. The fixed NBR bumpers absorb end-of-stroke shock without offering adjustable cushioning. Its short body depth saves axial mounting space while the through-rod geometry naturally resists twisting, allowing you to mount a work tool on one end and a dog on the opposite side.
Airtac SDAD Double Rod Slim Cylinder SDAD100X40 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD100X40 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø100 mm |
| Stroke | 40 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 SDAD100X40 Is Used
Heavy Pallet Lifting
Lifts 179.7 kg vertical loads safely using the 3524.9 N symmetric force, ensuring stable elevation without rotational drift.
Press Tooling Actuation
Drives a forming tool on one rod end while the opposite end remains free for mechanical tracking, utilizing the anti-twist through-rod geometry.
Guided Strip Alignment
Squares heavy metal strips in a mill line, relying on the equal push and pull forces to prevent binding during reversal.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD100X40 the Right Cylinder?
When sizing this model, compare it to the adjacent SDAD80, which yields 2267.8 N at 0.5 MPa. If that lower capacity is insufficient, the SDAD100X40 provides a significant jump to 3524.9 N. Since this is the largest bore in the series, there is no larger standard option available. At 0.5 MPa, the safe working load is roughly 2115 N, which translates to a vertical lift capacity of about 179.7 kg with a 2:1 safety margin.
This specific SKU lacks the S magnet option, so it cannot directly mount AirTAC reed or electronic switches. The female M18x1.5 rod threads are standard. Remember that a standard cylinder drifts when air is removed or a valve centers; the NBR bumper only decelerates the stroke end and will not hold the load. Use an external rod lock or pilot-operated check valve for load holding.
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 SDAD100X40 FAQ
The SDAD100X40 generates 3524.9 N at 0.5 MPa and 4934.8 N at 0.7 MPa in both directions, with a theoretical maximum of 719 kgf at 1.0 MPa. Because it is a double-rod cylinder, the extend and retract forces are identical.
No, this specific model does not include the S magnet option, so it cannot accept AirTAC reed or electronic switches. You would need the SDAD100X40S variant for position sensing capabilities.
