Airtac SDAD Double Rod Slim Cylinder SDAD63X65S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X65S 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 SDAD63X65S
The AirTAC SDAD63X65S is a compact double-acting cylinder featuring a 63mm bore and a 65mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in both chambers. This geometry ensures push force equals pull force, delivering exactly 1401.5 N at 0.5 MPa in either direction. The through-rod design inherently resists twisting, providing stable linear motion for demanding setups.
Equipped with a built-in magnet (-S), this unit interfaces directly with AirTAC reed or electronic switches for end-of-stroke sensing. The short body footprint saves valuable axial mounting depth compared to standard round-body cylinders. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs shock without requiring manual adjustment. With a 20mm rod diameter and PT1/4 air port, it operates efficiently between 30 and 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD63X65S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X65S |
|---|---|
| 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 SDAD63X65S Is Used
Symmetric Gripper Actuation
Drives opposing gripper jaws where equal 1401.5 N clamping force is required in both open and close directions to prevent part deformation.
Vertical Lift Stations
Lifts 71.4 kg payloads with a 2:1 safety margin, using the through-rod to maintain vertical stability and resist torsional sag during elevation.
Dual-End Tooling Transfer
Mounts a forming tool on the front rod and a position dog on the rear rod, allowing external sensors to confirm the 65mm stroke completion without interfering with the work area.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X65S the Right Cylinder?
When sizing this model, consider the adjacent bores for your force requirements. Stepping down, 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 SDAD63X65S strikes a middle ground, offering a safe working load of roughly 841 N (about 60% of its 1401.5 N capacity) and a vertical lift capability of approximately 71.4 kg with a 2:1 safety margin.
The dual-end rod allows you to drive a tool on one side while mounting a switch dog on the opposite side. Remember that a plain 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. This configuration includes the -S magnet and female M10x1.5 rod-end threads on both ends.
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 SDAD63X65S FAQ
The double-rod design provides equal force in both directions: 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. The theoretical maximum is 286 kgf at 1.0 MPa.
Yes, the through-rod exits both ends, allowing you to mount a tool on one side and a switch dog on the other. The built-in magnet (-S) works with AirTAC reed or electronic switches for position detection.
