Airtac SDAD Double Rod Slim Cylinder SDAD63X65SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X65SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 65mm 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 SDAD63X65SB
The AirTAC SDAD63X65SB is a compact, double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies each chamber equally, the annular area matches on extend and retract, yielding identical push and pull forces of 1401.5 N at 0.5 MPa. This symmetric output is ideal for balanced tooling loads.
The 63 mm bore uses a 20 mm rod and PT1/4 port, while the -B option specifies male M18x1.5 threads on both ends. The -S code adds a piston magnet for position sensing. Its short profile saves axial mounting depth, and a fixed NBR bumper decelerates the stroke ends without acting as a lock.
Airtac SDAD Double Rod Slim Cylinder SDAD63X65SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X65SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 65 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 SDAD63X65SB Is Used
Dual-End Guiding Jig
Uses the anti-rotation through-rod to drive a clamp on one end while a dog triggers a switch on the opposite end, maintaining precise alignment without twisting.
Symmetric Lift Station
Handles vertical lifting tasks requiring equal push and pull forces, leveraging the 1401.5 N output to raise and lower balanced loads smoothly.
Reciprocating Transfer Unit
Mounts a pusher plate on one male M18x1.5 rod end and a counterweight on the other, ensuring stable force distribution during rapid back-and-forth part transfers.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X65SB the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD50 provides 824.7 N, while the SDAD80 offers 2267.8 N at 0.5 MPa. The 63 mm bore delivers 1401.5 N, providing a safe working load around 841 N, which translates to a vertical lift capacity of roughly 71.4 kg with a 2:1 safety margin. The through-rod design resists twisting and permits mounting a tool on one end and a dog on the opposite side.
This configuration includes the -S magnet for AirTAC reed or electronic switches and -B male M18x1.5 rod threads at both ends. Remember that a plain cylinder drifts when air is lost or a valve centers; the fixed bumper only decelerates near stroke end. For load holding without live pressure, install 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 SDAD63X65SB FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It provides 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 through-rod resists twisting and allows mounting tooling on both ends. This model includes the -S magnet for reed or electronic switches and -B male M18x1.5 threads on both rods.
