Airtac SDAD Double Rod Slim Cylinder SDAD63X55S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X55S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 55mm 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 SDAD63X55S
The AirTAC SDAD63X55S is a double-acting, double-rod compact cylinder featuring a 63mm bore and a 55mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber, yielding an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric thrust is highly advantageous for driving loads that require consistent momentum in both directions.
A built-in piston magnet allows integration with AirTAC reed or electronic switches for end-of-stroke detection. The through-rod geometry inherently resists twisting, letting you mount a work tool on one end while a dog or sensor reads position on the opposite side. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X55S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X55S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 55 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 SDAD63X55S Is Used
Symmetric Lift Stations
Drives elevating platforms with 1401.5 N of equal force in both directions, ensuring smooth ascent and descent without momentum shifts.
Dual-End Transfer Arms
Uses the anti-rotation through-rod to push a part on one end while a dog triggers an electronic switch on the opposite end simultaneously.
Non-Rotating Press Tools
Mounts a stamping tool on one rod end where the fixed NBR bumper absorbs the 55mm stroke shock, resisting twist during high-cycle pressing.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X55S the Right Cylinder?
When sizing this model, compare its双向 thrust against neighboring bores: stepping down to the SDAD50 provides 824.7 N at 0.5 MPa, while stepping up to the SDAD80 yields 2267.8 N at 0.5 MPa. The 63mm bore uses a PT1/4 air port and a 20mm rod diameter at both ends. This specific configuration includes the -S magnet option and standard female M10x1.5 rod-end threads.
For application planning, the safe working load is approximately 841 N, representing about 60 percent of the 0.5 MPa output, with a vertical lift capacity near 71.4 kg at a 2:1 safety margin. Note that a standard cylinder does not hold position if air pressure is lost or the valve is centered; the piston will drift. For load holding without live pressure, install 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 SDAD63X55S 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 through-rod resists twisting under load and allows you to mount a tool on one end while using the other end for a sensor dog. The built-in magnet works with AirTAC reed or electronic switches.
