Airtac SDAD Double Rod Slim Cylinder SDAD63X40SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X40SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm 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 SDAD63X40SB
The AirTAC SDAD63X40SB is a compact double-acting cylinder featuring a 63 mm bore and a 40 mm stroke. Its through-rod design exits both ends of the riveted body, yielding identical annular areas so the push and pull forces match exactly at 1401.5 N under 0.5 MPa. This symmetric output is ideal for balancing loads without tweaking pressure regulators.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this unit supports position feedback at either end. The -B option specifies male M18x1.5 rod threads on both sides, while the fixed NBR bumpers absorb end-of-stroke shocks within the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD63X40SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X40SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 40 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 1402 N |
| 0.7 MPa | 1962 N |
| Max (@1.0 MPa) | 286 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 SDAD63X40SB Is Used
Symmetric Lift Station
Drives a lifting platform where the equal 1401.5 N push and pull forces prevent sagging during vertical material handling.
Dual-End Transfer
Uses the male M18x1.5 threads to mount a gripper on one side and a cam for a reed switch on the other, saving layout space.
Anti-Rotation Press
The through-rod resists twisting during a 40 mm stamping operation, maintaining precise alignment for small component assembly.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X40SB the Right Cylinder?
When sizing this 63 mm bore actuator, consider its neighbours: the SDAD50 provides 824.7 N at 0.5 MPa, whereas the larger SDAD80 jumps to 2267.8 N. The 1401.5 N output here offers a safe working load of roughly 841 N (about 60 percent of capacity) and a vertical lift capability near 71.4 kg with a 2:1 margin. The through-rod geometry resists twisting, allowing you to drive a tool on one end and mount a dog on the opposite side.
Remember that a standard compact cylinder drifts when air is lost or the valve centres, as the fixed bumper only decelerates near stroke end rather than locking the piston. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration uses a PT1/4 port, male M18x1.5 rods, and a maximum standard stroke of 130 mm.
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 SDAD63X40SB FAQ
Because the rod occupies both chambers, the push and pull forces are identical: 1401.5 N at 0.5 MPa, 1962.2 N at 0.7 MPa, and a theoretical maximum of 286 kgf at 1.0 MPa in both directions.
No, the piston will drift if air is lost or the valve centres, as the fixed NBR bumper only decelerates the stroke end. You must add an external rod lock or pilot-operated check valve for load holding.
