Airtac SDAD Double Rod Slim Cylinder SDAD63X80SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X80SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 80mm 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 SDAD63X80SB
The AirTAC SDAD63X80SB is a compact, double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies both chambers, the annular area remains identical in either direction, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is ideal for driving loads that require consistent kinetic energy regardless of travel direction.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this unit also features male M18x1.5 threads (-B) on both 20 mm rod ends. The short body geometry minimizes axial mounting depth, while fixed NBR bumpers absorb end-of-stroke impacts. Operating at speeds of 30-500 mm/s, it handles a safe working load of roughly 841 N, providing a 2:1 margin for vertical lifts up to 71.4 kg.
Airtac SDAD Double Rod Slim Cylinder SDAD63X80SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X80SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 80 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 SDAD63X80SB Is Used
Symmetric Lift Stations
Drives vertical elevators with 1401.5 N of matched force extending and retracting, preventing sag on the upstroke while handling 71.4 kg vertical lifts safely.
Dual-End Transfer Arms
Uses the anti-rotation through-rod to push a part with one male M18x1.5 end while the opposite end trips a reed or electronic switch without torsional deflection.
Compact Forming Jigs
Fits into shallow machine frames using the riveted body, applying equal clamping pressure in both directions over the 80 mm travel for consistent carton sealing.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X80SB the Right Cylinder?
When sizing this unit, compare its 1401.5 N output at 0.5 MPa against adjacent bores: the SDAD50 provides 824.7 N, whereas the SDAD80 jumps to 2267.8 N. This 63 mm bore strikes a balance for medium-force symmetric tasks. The through-rod design resists twisting and permits mounting a tool on one end with a position dog on the opposite side. Confirm your setup requires an 80 mm stroke, PT1/4 port, male M18x1.5 rod threads, and switch readiness.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. The fixed NBR bumper only decelerates the stroke near its limits and acts neither as an adjustable air cushion nor a braking lock. For suspended loads, integrate an external rod lock or a 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 SDAD63X80SB FAQ
The double-rod design provides 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. For a safe 2:1 design margin, keep the working load around 841 N, which supports a vertical lift of approximately 71.4 kg.
The through-rod prevents rotation and allows you to mount tooling on one male M18x1.5 end while using the opposite end to trigger a reed or electronic switch via the built-in magnet. This dual-end geometry provides precise tracking and symmetric operation in tight spaces where a longer profile cylinder cannot fit.
