Airtac SDAD Double Rod Slim Cylinder SDAD63X65
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X65 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 65mm 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 SDAD63X65
The AirTAC SDAD63X65 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, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is highly advantageous for loads requiring consistent driving power in both stroke directions.
A 20mm piston rod resists mechanical twisting during operation. The short body footprint saves axial mounting depth compared to standard round-body cylinders. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet and therefore cannot support magnetic position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD63X65 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X65 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 65 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 SDAD63X65 Is Used
Web Guiding Mechanism
Utilizes the dual-end rod to mount a guide roller on one side and a tracking sensor flag on the other, relying on the 1401.5 N equal force to prevent twisting during material correction.
Symmetric Lift Station
Drives a 65mm vertical lift platform where the identical extend and retract thrust ensures smooth, balanced elevation without jerky transitions, safely handling loads near 71.4 kg.
Dual-Side Carton Sealer
Employs the compact riveted body to fit within a tight conveyor frame, driving sealing jaws from both ends simultaneously to fold flaps securely at up to 500 mm/s.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X65 the Right Cylinder?
When sizing this actuator, consider the neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, while the larger SDAD80 offers 2267.8 N at 0.5 MPa. The 63mm bore provides a computed safe working load of roughly 841 N, assuming a 60 percent safety margin of the 1401.5 N figure. Vertically, it can lift around 71.4 kg with a 2:1 margin. This model features a 65mm stroke, a PT1/4 port, and female M10x1.5 rod-end threads on both ends.
The through-rod geometry allows you to mount a work tool on one side and a physical dog or cam on the opposite end. 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, integrate an external rod lock or a pilot-operated check valve. Operating speed ranges from 30 to 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 SDAD63X65 FAQ
The push and pull forces are equal because of the double-rod design. It generates 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 protrudes from both ends, allowing you to drive a tool on one side while attaching a mechanical dog to the other. However, this specific SKU lacks a piston magnet, so it cannot trigger magnetic reed or electronic switches; you would need the -S variant for that capability.
