Airtac SDAD Double Rod Slim Cylinder SDAD63X65B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X65B 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 SDAD63X65B
The AirTAC SDAD63X65B is a compact double-acting cylinder featuring a 63 mm bore and 65 mm stroke. Because the piston rod exits both ends, the annular area remains identical in both directions, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is ideal for balanced actuation tasks.
The through-rod geometry inherently resists twisting, allowing you to mount a work tool on one end and a dog or limit switch on the opposite side. The -B option equips both extending ends with male M18x1.5 threads for secure mechanical attachment. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable air cushions.
Airtac SDAD Double Rod Slim Cylinder SDAD63X65B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X65B |
|---|---|
| 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 SDAD63X65B Is Used
Web Guiding Mechanism
Uses the anti-rotation through-rod to steer film or foil without twisting, maintaining precise edge tracking under symmetric load.
Dual-End Transfer Arm
Mounts a grip on one male M18x1.5 end and a cam dog on the opposite, synchronizing pick-and-place movements efficiently.
Balanced Lift Station
Raises and lowers a 71.4 kg platen vertically, exploiting the equal 1401.5 N push and pull force to prevent gravitational drift mid-stroke.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X65B the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the SDAD80 offers 2267.8 N. The 63 mm bore sits perfectly between them, providing a safe working load of roughly 841 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 71.4 kg with a 2:1 safety margin.
This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; choose the -S variant if position sensing is required. Note that a standard cylinder drifts when air pressure is lost or the valve centers—the fixed bumper only decelerates near stroke end, so add an external rod lock or pilot-operated check valve for load holding. Operating speed spans 30-500 mm/s via the PT1/4 port.
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 SDAD63X65B FAQ
The double-rod design ensures equal force in both directions: 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The theoretical maximum is 286 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one end while mounting a dog on the other. This -B variant features male M18x1.5 threads on both rod ends for secure fastening.
