Airtac SDAD Double Rod Slim Cylinder SDAD50X75S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X75S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm 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 SDAD50X75S
The AirTAC SDAD50X75S is a double-acting, double-rod compact cylinder featuring a 50mm bore and a 75mm stroke. Because the piston rod extends from both ends, the annular area remains identical in both chambers, ensuring push force equals pull force at 824.7 N each way under 0.5 MPa. This symmetric thrust is ideal for balanced actuation. The short riveted body minimizes axial mounting depth, fitting where larger profile cylinders cannot.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The 20mm through-rod resists twisting during operation and allows driving a tool on one end while mounting a dog on the opposite side. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X75S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X75S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X75S Is Used
Symmetric Transfer Chuck
Uses the equal 824.7 N push and pull force to grip and release delicate wafers without imparting rotational torque on the handler.
Dual-End Lift Station
Mounts a lifting jaw on one rod end and a position dog on the opposite end, leveraging the 20mm through-rod for precise vertical elevation.
Carton Flap Folder
Employs the 75mm stroke and fixed NBR bumper to cleanly fold heavy cardboard flaps, absorbing the end shock without requiring adjustable cushions.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X75S the Right Cylinder?
When sizing this model, consider the neighboring bores: stepping down to the SDAD40 yields 527.8 N at 0.5 MPa, while stepping up to the SDAD63 provides 1401.5 N at 0.5 MPa. For the SDAD50X75S, a safe working load is approximately 495 N (about 60 percent of the 824.7 N figure), translating to a vertical lift capacity of roughly 42 kg with a 2:1 safety margin. The through-rod geometry prevents rotation and enables dual-end mounting.
Confirm the 50mm bore, 75mm stroke, and PT1/4 air port suit your pneumatic supply. This variant includes the -S magnet for switch integration and features female M10x1.5 rod-end threads on both ends. Note that 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, install 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 SDAD50X75S FAQ
The push and pull forces are equal because of the double-rod design. It generates 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
Yes, the 20mm through-rod exits both sides of the riveted body, resisting twist and allowing you to drive a tool on one end while mounting a reed or electronic switch dog on the other. The -S magnet enables this position sensing.
