Airtac SDAD Double Rod Slim Cylinder SDAD63X35
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X35 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 35mm 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 SDAD63X35
The AirTAC SDAD63X35 is a double-acting, double-rod compact cylinder featuring a 63mm bore and 35mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber. This geometry ensures push force equals pull force, delivering exactly 1401.5 N at 0.5 MPa in both directions. The through-rod design inherently resists twisting, providing stable linear motion for demanding setups.
This model uses a 20mm diameter rod at each end with a PT1/4 air port. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. The short body depth saves valuable axial mounting space. Note this specific SKU lacks a piston magnet, so it cannot directly host reed or electronic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD63X35 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X35 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 35 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 SDAD63X35 Is Used
Gripper Synchronization
Drives opposing gripper jaws where the 1401.5 N equal bidirectional force ensures perfectly balanced clamping pressure on heavy billets.
Elevator Counterbalance
Lifts a 71.4 kg vertical load using the through-rod to mount a secondary cam on the rear end for upper-limit mechanical signaling.
Transfer Pusher
Pushes pallets along a conveyor while the anti-rotation properties of the dual rods prevent workpiece skewing during transit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X35 the Right Cylinder?
When sizing this unit, compare its output against adjacent bores. Stepping down, the SDAD50 provides 824.7 N at 0.5 MPa, whereas stepping up to the SDAD80 yields 2267.8 N at 0.5 MPa. The 63mm bore offers a safe working load of roughly 841 N, which is about 60 percent of the 1401.5 N figure at 0.5 MPa. This translates to a vertical lift capacity near 71.4 kg when applying a 2:1 safety margin.
The through-rod allows you to drive a tool on one end while mounting a dog or fixture on the opposite side. Remember that a plain SDAD does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration features a 35mm stroke, female M10x1.5 rod-end threads, and no magnet.
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 SDAD63X35 FAQ
The push and pull forces are identical 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. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You would need the SDAD63X35S variant for position sensing. However, the through-rod design lets you mount a dog or external target on the opposite end for external sensing.
