Airtac SDAD Double Rod Slim Cylinder SDAD63X90SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X90SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 90mm 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 SDAD63X90SB
The AirTAC SDAD63X90SB 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 thrust is highly advantageous when driving loads that must remain balanced throughout the full cycle.
Equipped with a built-in magnet (-S), this unit interfaces directly with AirTAC reed or electronic switches via the body sensor grooves. The -B option specifies male M18x1.5 rod threads on both ends, while the 20 mm piston rod diameter provides robust resistance to twisting. A fixed NBR bumper at each end decelerates the 90 mm stroke, and the short body profile conserves axial mounting depth.
Airtac SDAD Double Rod Slim Cylinder SDAD63X90SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X90SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 90 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 SDAD63X90SB Is Used
Gripper Jaw Synchronization
Drives opposing gripper arms with equal 1401.5 N force in both directions, ensuring parallel clamping on heavy cast parts without rotational deflection.
Elevator Stage Lift
Lifts a 71.4 kg vertical platform stage using the dual-end male M18x1.5 threads, maintaining stable elevation through the 90 mm travel.
Dual-Side Transfer Pusher
Pushes a workpiece from one conveyor belt to another while simultaneously triggering a reed or electronic switch on the opposing rod end for timing confirmation.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X90SB the Right Cylinder?
When sizing this 63 mm bore, consider the SDAD50 which provides 824.7 N at 0.5 MPa, or step up to the SDAD80 which yields 2267.8 N at 0.5 MPa. The SDAD63X90SB bridges that gap efficiently, offering a safe working load of roughly 841 N (about 60 percent of its 1401.5 N capacity) and a vertical lift capability near 71.4 kg with a 2:1 safety margin.
The through-rod geometry prevents rotation and permits mounting a tool on one end while fitting a dog or switch on the opposite side. Remember that a standard cylinder does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This configuration includes the PT1/4 port, female M10x1.5 body threads, male M18x1.5 rod threads, and operates at 30-500 mm/s.
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 SDAD63X90SB FAQ
The push and pull forces are equal because of the double-rod design. It generates 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. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to attach a work tool via the male M18x1.5 threads on one end while mounting a dog to trigger a reed or electronic switch on the opposite end. The 20 mm rod diameter also helps resist twisting during operation.
