Airtac SDAD Double Rod Slim Cylinder SDAD63X15SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X15SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 15mm 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 SDAD63X15SB
The AirTAC SDAD63X15SB is a double-acting compact cylinder featuring a 63mm bore and 15mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 1401.5 N at 0.5 MPa in each direction. The short footprint saves valuable axial mounting depth where larger profile cylinders cannot fit.
This specific configuration includes a built-in piston magnet for position sensing alongside male M18x1.5 threaded rods on both ends. The through-rod design inherently resists twisting, allowing you to drive a tool on one side while mounting a dog or switch on the opposite end. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X15SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X15SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 15 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 SDAD63X15SB Is Used
Symmetric Gripper Actuation
Drives a synchronized gripping jaw on one end while the opposite rod end mounts a dog to trigger a reed switch, utilizing the equal 1401.5 N push and pull force.
Vertical Lift Stations
Lifts a 71.4 kg payload with a 2:1 safety margin, relying on the through-rod to resist twisting during elevation within a tight 15mm stroke envelope.
Dual-End Tooling Drive
Mounts a male M18x1.5 threaded tool on one side and a secondary assembly head on the other, taking advantage of the compact riveted body to minimize machine footprint.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X15SB the Right Cylinder?
When sizing this unit, compare its output against neighboring bores. Stepping down to the SDAD50 yields 824.7 N at 0.5 MPa, whereas stepping up to the SDAD80 provides 2267.8 N at 0.5 MPa. For this 63mm bore, a safe working load is approximately 841 N, representing 60 percent of the 0.5 MPa figure. In a vertical lift scenario, it can manage roughly 71.4 kg with a 2:1 safety margin.
The dual-end through-rod provides excellent anti-rotation stability for symmetric loads. Remember that a standard cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near stroke end and never acts as a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This model confirms a 63mm bore, 15mm stroke, PT1/4 port, an S magnet for reed or electronic switches, and B male M18x1.5 rod threads.
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 SDAD63X15SB FAQ
The force is equal in both directions due to the double-rod design. It provides 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a theoretical maximum of 286 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod exits both ends with male M18x1.5 threads. You can mount a tool on one end and a position dog on the other. The design also resists rotation, but ensure you leave clearance for the rod exiting both sides.
