Airtac SDAD Double Rod Slim Cylinder SDAD63X70SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X70SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 70mm 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 SDAD63X70SB
The AirTAC SDAD63X70SB is a double-acting compact cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, giving you exactly 1401.5 N of push and pull force at 0.5 MPa. This symmetry prevents twisting and simplifies the driving of dual tooling.
This specific configuration includes a built-in piston magnet for reed or electronic switches, plus male M18x1.5 threads on both rod ends. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the 70 mm stroke operates within the 30 to 500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD63X70SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X70SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 70 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 SDAD63X70SB Is Used
Symmetric Transfer Arms
Drives a pick-and-place arm from both ends, utilizing the 1401.5 N equal force to move 71.4 kg vertical loads smoothly without rotational twist.
Dual-End Machining Fixture
Mounts a clamp on one rod end and a proximity dog on the other, using the male M18x1.5 threads for secure tooling attachment in tight riveted-body envelopes.
Anti-Rotation Guiding Jig
Resists side torque during material pressing operations, maintaining alignment where a single rod might twist under asymmetric 0.7 MPa loads.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X70SB the Right Cylinder?
When sizing this 63 mm bore, compare its 1401.5 N @0.5 MPa output with neighboring models. Dropping down to the SDAD50 yields 824.7 N, while stepping up to the SDAD80 provides 2267.8 N. For this cylinder, a safe working load is approximately 841 N (about 60 percent of the 0.5 MPa figure), allowing a vertical lift of roughly 71.4 kg with a 2:1 safety margin.
The through-rod geometry lets you mount a work tool on one side and a position dog on the opposite end. Remember that a plain cylinder drifts when air is lost or the valve centers, as the fixed bumper only decelerates near stroke end and acts as no lock; use an external rod lock or pilot-operated check valve for load holding. This unit features a PT1/4 port, male M18x1.5 rod threads, and the S magnet option.
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 SDAD63X70SB FAQ
The push and pull forces are equal at 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
The through-rod provides equal force in both directions and resists rotation. It allows you to mount a tool on one end and a position dog on the other. The S option includes a magnet for reed or electronic switches, and the B option provides male M18x1.5 threads on both ends.
