Airtac SDAD Double Rod Slim Cylinder SDAD40X100S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X100S 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 SDAD40X100S
The AirTAC SDAD40X100S is a compact double-acting cylinder featuring a 16 mm piston rod exiting both ends of its riveted body. Because the rod occupies each chamber equally, the annular area matches on extend and retract, yielding identical push and pull forces of 527.8 N at 0.5 MPa. This symmetric output is ideal for balanced tooling loads.
The through-rod geometry provides inherent anti-rotation resistance and allows you to drive a work tool on one end while mounting a position dog on the opposite side. Equipped with a built-in magnet, this unit supports AirTAC reed or electronic switches. End-of-stroke energy is managed by a fixed NBR bumper, which decelerates the piston rather than acting as an adjustable air cushion. Operating speed ranges from 30 to 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD40X100S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X100S |
|---|---|
| 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 SDAD40X100S Is Used
Gripper Jaw Synchronization
Drives opposing gripper arms where the 527.8 N equal bidirectional force ensures balanced clamping pressure on precision metal parts.
Dual-End Transfer Mechanism
Mounts a pick-and-place head on one rod end and a cam dog on the opposite end to trigger a reed switch without adding external length.
Vertical Lift Station
Raises a 26.9 kg workpiece fixture using the anti-rotation through-rod to prevent load twisting during the 100 mm vertical ascent.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X100S the Right Cylinder?
When sizing this 40 mm bore, compare its 527.8 N output at 0.5 MPa with neighbouring models. Dropping down to the SDAD32 provides 345.6 N, whereas stepping up to the SDAD50 yields 824.7 N.
The dual-end through-rod prevents twisting during operation, but remember that a plain cylinder drifts if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates near the stroke end and does not lock the load; use an external rod lock or pilot-operated check valve for secure holding. This configuration includes the S magnet for sensing and features female M8x1.25 rod-end threads on both sides, with a PT1/8 air 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 SDAD40X100S FAQ
Because the double-rod design provides equal annular area both ways, push and pull forces are identical: 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. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod exits both ends, allowing you to drive a tool on one side and mount a dog for a switch on the other. This specific model includes the S magnet for AirTAC reed or electronic switches, and the short riveted body saves axial mounting depth.
