Airtac SDAD Double Rod Slim Cylinder SDAD63X5S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X5S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 5mm 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 SDAD63X5S
The AirTAC SDAD63X5S is a compact double-acting cylinder featuring a 63mm bore and a 5mm stroke, engineered with twin piston rods exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for balancing loads, while the through-rod geometry inherently resists twisting during rapid micro-movements.
The short riveted body drastically saves axial mounting depth where a larger profile cylinder would fail to fit. It includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, and the PT1/4 port supplies air efficiently to the 20mm rods.
Airtac SDAD Double Rod Slim Cylinder SDAD63X5S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X5S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 5 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 SDAD63X5S Is Used
Short-Stroke Clamping
Provides 1401.5 N of equal bidirectional force for securing heavy castings during machining without rotational deflection.
Symmetric Lift Stations
Drives a lift platform on one rod end while the opposite end triggers an electronic switch, ensuring perfectly balanced vertical motion.
Dual-Action Transfer
Pushes and pulls a shuttle carriage with identical 1962.2 N force at 0.7 MPa, maintaining stable momentum reversal.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X5S the Right Cylinder?
When sizing this unit, compare its 1401.5 N output at 0.5 MPa against its neighbours: the SDAD50 provides 824.7 N, whereas the SDAD80 offers 2267.8 N. For this 63mm bore, a safe working load is approximately 841 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 71.4 kg with a 2:1 safety margin. The twin-rod design allows you to drive a tool on one end and mount a position dog on the opposite end simultaneously.
This configuration specifies a 5mm stroke, a PT1/4 port, female M10x1.5 rod-end threads, and the -S magnet option. Remember that a plain cylinder does not hold its load if air pressure drops or the valve centres—the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDAD63X5S FAQ
The double-rod design produces 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 maximum operating pressure is 1.0 MPa.
Yes, the through-rod exits both ends, allowing you to mount a work tool on one side and a position dog for a reed or electronic switch on the other. The fixed NBR bumper decelerates the stroke end but does not function as a lock.
