Airtac SDAD Double Rod Slim Cylinder SDAD40X60B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD40X60B 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 SDAD40X60B
The AirTAC SDAD40X60B is a compact double-acting cylinder featuring a 40mm bore and 60mm stroke. Its through-rod design exits both ends of the riveted body, yielding identical annular areas so push and pull forces match exactly at 527.8 N each way under 0.5 MPa. This symmetry prevents twisting during operation, providing stable guidance for rigid payloads.
Equipped with male M14x1.5 threads on both rod ends, this 60mm travel unit saves axial mounting depth compared to standard profile bodies. It uses a fixed NBR bumper to absorb end-of-stroke shock rather than an adjustable cushion. Note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to an -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD40X60B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD40X60B |
|---|---|
| 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 SDAD40X60B Is Used
Web Guiding
Drives a steering roller on one male rod end while the opposite end carries a tracking flag, utilizing the equal 527.8 N push/pull force to keep film webs centered without rotational deflection.
Transfer Chuck
Shifts a dual-sided gripper between two machining stations, relying on the 60mm stroke and matched bidirectional force to move parts smoothly without twisting on the transfer arm.
Lift Stopper
Raises and lowers a pallet stopper pin in a conveyor line, taking advantage of the compact riveted body to fit within tight vertical clearance envelopes while lifting up to 26.9 kg safely.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD40X60B the Right Cylinder?
When sizing this 40mm bore model, consider the neighboring bores: stepping down to SDAD32 provides 345.6 N at 0.5 MPa, while stepping up to SDAD50 yields 824.7 N. The SDAD40X60B strikes a middle ground with 527.8 N at 0.5 MPa, offering a safe working load of roughly 317 N (about 60 percent of capacity) and a vertical lift capability near 26.9 kg with a 2:1 safety margin.
This configuration features PT1/8 ports and male M14x1.5 rod threads on both ends. The through-rod geometry allows driving a tool on one side while mounting a dog or fixture on the opposite end. Remember that a standard cylinder drifts when air pressure drops or the valve centers; the fixed bumper only decelerates near stroke end. For secure load holding without live pressure, integrate 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 SDAD40X60B FAQ
Because the double-rod design creates equal annular areas, force is identical 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod exits both ends, allowing you to drive a tool on one side and mount a dog or fixture on the other while resisting rotational twist. However, this specific SKU lacks a piston magnet, so it cannot directly accept a magnetic switch; you would need the -S variant for reed or electronic sensing.
