Airtac SDAD Double Rod Slim Cylinder SDAD63X45SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X45SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 45mm 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 SDAD63X45SB
The AirTAC SDAD63X45SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area remains constant, yielding identical push and pull forces of 1401.5 N at 0.5 MPa. This symmetric thrust is highly advantageous for manipulating balanced loads without torque bias.
This specific configuration includes a built-in piston magnet for position sensing alongside male M18x1.5 rod threads on both ends. The short body design drastically reduces axial mounting depth compared to traditional round-body units. End-of-stroke deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions, operating reliably within a 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD63X45SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X45SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 45 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 SDAD63X45SB Is Used
Symmetric Lift Stations
Drives a 71.4 kg vertical lift platform with a 2:1 safety margin. Equal push and pull forces ensure the platform travels smoothly up and down without shifting momentum bias.
Dual-End Transfer Arms
Mounts a gripping jaw on one male M18x1.5 rod end and a magnetic switch dog on the opposite end. The through-rod prevents rotational twist during high-speed part transfers.
Balanced Pinching Mechanisms
Executes 1401.5 N of clamping force in both directions. The compact riveted body fits into tight machine frames while maintaining precise, equal-force actuation on the return stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X45SB the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD50 provides 824.7 N at 0.5 MPa, while moving up to the SDAD80 offers 2267.8 N. The 63 mm bore strikes a middle ground, offering a safe working load of roughly 841 N (about 60% of the 0.5 MPa rating) and a vertical lift capacity of approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one male M18x1.5 end and a position dog on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the NBR bumper only decelerates the stroke end and will not hold the load. For secure vertical holding without live pressure, integrate an external rod lock or pilot-operated check valve. This model features a PT1/4 port, a 20 mm rod diameter, and the -S magnet compatible with reed or electronic switches.
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 SDAD63X45SB FAQ
The double-rod design provides equal force in both directions: 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. The maximum operating pressure is 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod exits both ends with male M18x1.5 threads, allowing you to drive a tool on one side and mount a sensor dog on the other. The -S magnet enables tracking via AirTAC reed or electronic switches, while the geometry inherently resists rotation.
