Airtac SDAD Double Rod Slim Cylinder SDAD40X60S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X60S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø40mm bore, 60mm 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 SDAD40X60S
The AirTAC SDAD40X60S is a double-acting, double-rod compact cylinder featuring a 40 mm bore and a 60 mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber, yielding an equal push and pull force of 527.8 N at 0.5 MPa. This symmetric output is ideal for balanced loading, while the through-rod geometry inherently resists mechanical twisting during operation.
A built-in magnet enables position sensing with AirTAC reed or electronic switches fitted directly into the body grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. The short body footprint conserves axial mounting depth, and the 16 mm rods feature female M8x1.25 end threads on both sides for straightforward tool attachment.
Airtac SDAD Double Rod Slim Cylinder SDAD40X60S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X60S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø40 mm |
| Stroke | 60 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 SDAD40X60S Is Used
Web Guiding Mechanism
Utilizes the equal 527.8 N push and pull force to tension and steer material rolls symmetrically without twisting, ensuring tracking accuracy.
Dual-End Transfer Arm
Mounts a grip on one rod end and a cam dog on the opposite end to trigger an electronic switch, saving space in compact assembly cells.
Balanced Lift Station
Lifts platens vertically with matched force both ways, relying on the 16 mm through-rod to resist side loads and prevent load rotation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X60S the Right Cylinder?
When sizing this unit, compare its bidirectional 527.8 N output at 0.5 MPa against adjacent bores: the SDAD32 provides 345.6 N, whereas the SDAD50 delivers 824.7 N. This positions the 40 mm bore as a solid middle ground for medium-force tasks. The through-rod design allows you to drive a workpiece on one end while mounting a dog or sensor target on the opposite end, ensuring precise anti-rotation control.
This specific configuration includes the -S magnet for switch integration and female rod threads. Operating speed spans 30-500 mm/s, and the pneumatic port is PT1/8. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. For load-holding requirements without live pressure, install an external rod lock or a 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 SDAD40X60S 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, with a proof pressure of 1.5 MPa.
Yes, the through-rod resists rotation and allows tool mounting on one end while a dog triggers a switch on the other. The -S magnet in this model works with AirTAC reed or electronic switches fitted to the body grooves.
