Airtac SDAD Double Rod Slim Cylinder SDAD63X30S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X30S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 30mm 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 SDAD63X30S
The AirTAC SDAD63X30S 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 exactly 1401.5 N of push and pull force at 0.5 MPa. This symmetry is ideal for driving loads that require consistent kinetic energy regardless of travel direction.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for end-of-stroke sensing. The 63 mm bore utilizes a 20 mm rod and a PT1/4 port, while end-of-stroke deceleration is handled by a fixed NBR bumper. The short body design drastically reduces axial mounting depth compared to traditional round-body options.
Airtac SDAD Double Rod Slim Cylinder SDAD63X30S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X30S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 30 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 SDAD63X30S Is Used
Symmetric Transfer Gripper
Drives a dual-sided pick-and-place jaw requiring identical 1401.5 N clamping force during both extend and retract actions without twisting.
Balanced Vertical Lift
Raises and lowers a 71.4 kg packaging platen with a 2:1 margin, utilizing the through-rod to mount a dog on the top end for a solid-state sensor.
Anti-Rotation Spot Welder
Holds a welding electrode steady against side torque in a tight riveted body, saving axial depth while the fixed NBR bumper absorbs the 30 mm stroke end shock.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X30S the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD50 provides 824.7 N at 0.5 MPa, while moving up to the SDAD80 offers 2267.8 N. The 63 mm bore provides a computed safe working load of roughly 841 N (about 60% of the 0.5 MPa figure) and can vertically lift approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and allows mounting a tool on one end and a position dog on the opposite side. Note that a plain cylinder drifts when air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for load holding. This configuration includes the -S magnet, female M10x1.5 rod threads, and a 30 mm stroke.
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 SDAD63X30S FAQ
Because the rod exits both ends, push and pull forces are equal: 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, with a proof pressure of 1.5 MPa.
Yes, the double-rod design allows driving a tool on one side while mounting a dog for a reed or electronic switch on the opposite end. The through-rod also resists twisting, though an external rod lock is required to hold position during air loss.
