Airtac SDAD Double Rod Slim Cylinder SDAD63X50
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X50 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 50mm 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 SDAD63X50
The AirTAC SDAD63X50 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 on extend and retract, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is ideal for balanced tooling loads.
The 63 mm bore uses a 20 mm rod and a PT1/4 port. Its short body depth saves axial mounting space where larger profile cylinders fail to fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so position sensing is not supported without switching to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD63X50 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X50 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 50 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 SDAD63X50 Is Used
Symmetric Transfer Jaws
Drives gripping jaws that push and pull identical 71.4 kg vertical loads with equal 1401.5 N force, preventing twist during part handover.
Dual-End Lift Stations
Mounts a lift fork on one rod end and a cam dog on the opposite end, utilizing the anti-rotation through-rod to maintain vertical alignment.
Riveted Body Pressing
Fits into shallow machine frames using the compact riveted body to deliver 1962.2 N at 0.7 MPa for pressing small bearings without requiring deep axial clearance.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X50 the Right Cylinder?
When sizing this model, compare the 1401.5 N output at 0.5 MPa against adjacent bores. Stepping down, the SDAD50 provides 824.7 N; stepping up, the SDAD80 offers 2267.8 N. With a 2:1 safety margin, this 63 mm bore achieves a vertical lift capacity of roughly 71.4 kg, giving a safe working load of about 841 N.
The through-rod geometry resists twisting and permits mounting a tool on one end while driving a dog on the opposite side. Note that a plain cylinder drifts when air is lost or the valve centers, as the fixed NBR bumper only decelerates near stroke end and acts as neither a lock nor a brake. For load holding, install an external rod lock or pilot-operated check valve. This configuration specifies female M10x1.5 rod threads, a 50 mm stroke, 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 SDAD63X50 FAQ
The double-rod design provides equal force in both directions: 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 operating pressure range is 0.15 to 1.0 MPa.
Yes, the through-rod exits both sides to resist twisting, allowing you to drive a tool on one end and a dog on the other. This base model lacks a piston magnet, so if you need position sensing via reed or electronic switches, select the SDAD63X50S variant.
