Airtac SDAD Double Rod Slim Cylinder SDAD63X120B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X120B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 120mm 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 SDAD63X120B
The AirTAC SDAD63X120B 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 an equal push and pull force of 1401.5 N at 0.5 MPa. This symmetric output is highly advantageous for loads requiring consistent drive and retraction energy.
This specific configuration includes male M18x1.5 thread piston rods on both ends, allowing direct attachment of tooling or clevis mounts at either face. The 63 mm bore uses a PT1/4 air port and achieves a maximum standard stroke of 130 mm, meaning this 120 mm unit operates within the optimal range. The short body geometry saves axial mounting depth compared to conventional round-body units, while the fixed NBR bumper decelerates the piston near stroke ends.
Airtac SDAD Double Rod Slim Cylinder SDAD63X120B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X120B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 120 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 SDAD63X120B Is Used
Symmetric Ejector Station
Drives a part ejector on the front rod while using the rear rod extension to trip a mechanical dog, ensuring perfectly timed ejection with 1401.5 N of equal force.
Dual-Side Transfer Arm
Mounts a grip jaw on one male M18x1.5 end and a counterweight on the other to balance a horizontal transfer operation without twisting.
Balanced Lift Fixture
Lifts a 71.4 kg payload vertically using both rod ends to guide a carriage, relying on the equal annular areas to maintain smooth ascent and descent.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X120B the Right Cylinder?
When sizing this model, consider the neighboring bores: the SDAD50 provides 824.7 N at 0.5 MPa, whereas the SDAD80 offers 2267.8 N at 0.5 MPa. The 63 mm bore sits perfectly between these, delivering a computed safe working load of roughly 841 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity of approximately 71.4 kg with a 2:1 safety margin. The through-rod geometry inherently resists twisting and permits driving a tool on one end while mounting a dog or secondary mechanism on the opposite side.
Confirm the 63 mm bore, 120 mm stroke, PT1/4 port, and the male M18x1.5 rod threads are correct for your assembly. Note that this SKU lacks a piston magnet, so position sensing is not possible without the -S variant. A plain cylinder does not hold its load if air pressure is lost or the valve is centered; 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 SDAD63X120B FAQ
The push and pull forces are equal at 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. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
The through-rod resists twisting and allows you to mount tooling on both ends simultaneously. This specific B-option features male M18x1.5 threads on both rods for direct fastening. It lacks a piston magnet, so reed or electronic switches require the -S variant.
