Airtac SDAD Double Rod Slim Cylinder SDAD50X80S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X80S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 80mm 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 SDAD50X80S
The AirTAC SDAD50X80S is a double-acting compact cylinder featuring a 50mm bore and an 80mm stroke. Its through-rod design exits both ends of the riveted body, yielding identical annular areas so push and pull forces match exactly at 824.7 N each way under 0.5 MPa. This symmetric thrust is perfect for balanced tooling loads.
Equipped with a built-in magnet (-S), it triggers AirTAC reed or electronic switches via body sensor grooves. The short riveted body drastically cuts axial mounting depth compared to traditional round-body cylinders. End-of-stroke energy is managed by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X80S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X80S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 80 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 SDAD50X80S Is Used
Symmetric Gripper Actuation
Drives an opposing parallel gripper where the 824.7 N equal push/pull force ensures perfectly balanced clamping pressure on both strokes.
Vertical Lift Stations
Raises a 42 kg payload through an 80 mm vertical stroke, using the dual-end rod to mount a counterweight dog on the opposite end.
Anti-Twist Machining Fixture
Holds a drilling jig steady against side loads; the 20 mm through-rod prevents rotational deflection during the metal cutting process.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X80S the Right Cylinder?
Sizing this 50mm bore against its neighbors ensures correct fitment. Dropping down to the SDAD40 provides 527.8 N at 0.5 MPa, while stepping up to the SDAD63 yields 1401.5 N at 0.5 MPa. The SDAD50X80S sits comfortably in the middle, offering a safe working load around 495 N (roughly 60 percent of its 824.7 N capacity) and a vertical lift capability of about 42 kg with a 2:1 safety margin.
The through-rod inherently resists twisting, allowing you to mount a work tool on one end and a position dog on the opposite side. This unit includes the -S magnet for sensing and uses female M10x1.5 rod-end threads on both sides with a PT1/4 air port. Remember that a plain cylinder drifts when air is lost or the valve centers; utilize an external rod lock or pilot-operated check valve for strict 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 SDAD50X80S FAQ
Because the rod exits both ends, the push and pull forces are identical. It generates 824.7 N at 0.5 MPa, 1154.5 N at 0.7 MPa, and a maximum theoretical output of 168 kgf at 1.0 MPa in both directions.
Yes, the through-rod geometry allows driving a tool on one side while attaching a dog for a reed or electronic switch on the opposite end. The included -S magnet enables position sensing directly in the body grooves.
