Airtac SDAD Double Rod Slim Cylinder SDAD63X75S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD63X75S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø63mm bore, 75mm 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 SDAD63X75S
The AirTAC SDAD63X75S 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, giving you 1401.5 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balancing loads without shifting the center of gravity.
The 63 mm bore uses a 20 mm rod and a PT1/4 port. A built-in magnet (-S) enables position detection with AirTAC reed or electronic switches fitted directly into the body grooves. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, reducing impact without adding adjustable cushioning complexity.
Airtac SDAD Double Rod Slim Cylinder SDAD63X75S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD63X75S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 75 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 SDAD63X75S Is Used
Web Guiding Mechanism
Uses the dual-end through-rod to mount a guiding roller on one side and a position flag on the other, relying on equal 1401.5 N force to prevent web deflection.
Symmetric Lift Station
Drives a lifting platform where matching push and pull forces prevent jerky transitions, safely handling a 71.4 kg vertical load with a 2:1 margin.
Transfer Shuttle
Moves parts back and forth across a short 75 mm stroke, using the fixed NBR bumpers to absorb end impacts while the anti-rotation rod keeps the carriage aligned.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD63X75S the Right Cylinder?
When sizing this unit, compare its 1401.5 N output at 0.5 MPa with neighboring bores: the SDAD50 provides 824.7 N, while the SDAD80 offers 2267.8 N. For this 63 mm model, a safe working load is roughly 841 N (about 60 percent of the 0.5 MPa figure), allowing a vertical lift of approximately 71.4 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and permits mounting a tool on one end while placing a dog or switch on the opposite side. Remember that a standard cylinder drifts when air is removed or the valve centers; use an external rod lock or pilot-operated check valve for load holding. This configuration includes the S magnet and female M10x1.5 rod 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 SDAD63X75S FAQ
Because the double-rod design provides equal annular area in both directions, push and pull forces are identical: 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.
Yes, the through-rod exits both ends, allowing you to drive a tool on one side while mounting a dog for a reed or electronic switch on the opposite side. The -S magnet in this model enables solid-state or reed switch detection in the body grooves.
