Airtac SDAD Double Rod Slim Cylinder SDAD63X30SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X30SB 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 SDAD63X30SB
The AirTAC SDAD63X30SB is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because the rod occupies each chamber equally, the annular area remains constant, yielding identical push and pull forces of 1401.5 N at 0.5 MPa. This symmetric thrust is ideal for balanced actuation tasks.
Equipped with a built-in magnet (-S) for position sensing and male-thread rods (-B) at both ends, this 63mm bore unit operates at 30-500 mm/s. The short body design drastically reduces axial mounting depth compared to standard round-body cylinders, fitting into tight machine frames. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD63X30SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X30SB |
|---|---|
| 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 SDAD63X30SB Is Used
Symmetric Gauging Station
Utilizes the equal 1401.5 N bi-directional force to push and pull a precision gauge without deflection, ensuring consistent measurement across the part.
Dual-End Transfer Arm
Mounts a pick tool on one male M18x1.5 rod end and a position dog on the opposite end, leveraging the anti-rotation through-rod for stable part handling.
Vertical Lift Fixture
Lifts a 71.4 kg payload with a 2:1 safety margin, relying on the compact riveted body to fit within tight vertical elevator channels.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X30SB the Right Cylinder?
When sizing this model, consider the 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. The 63mm bore offers a computed safe working load of roughly 841 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and allows mounting a tool on one end and a dog on the opposite side. This configuration includes a PT1/4 port, a 30mm stroke, and male M18x1.5 rod threads. Remember that a plain cylinder drifts when air is lost; use an external rod lock or pilot-operated check valve for load holding.
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 SDAD63X30SB FAQ
The push and pull forces are identical because of the double-rod design. It generates 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 -S option includes a built-in piston magnet compatible with AirTAC reed or electronic switches. However, the cylinder will not hold a load if air pressure is lost; you must add an external rod lock or pilot-operated check valve for secure load holding.
