Airtac SDAD Double Rod Slim Cylinder SDAD80X50S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X50S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 50mm 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 SDAD80X50S
The AirTAC SDAD80X50S is an 80 mm bore, 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 exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetric thrust is ideal for driving heavy loads without reversing torque bias.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches via the body sensor grooves. The 25 mm piston rod uses an M14x1.5 female thread at both ends, while the PT3/8 port supplies air. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X50S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X50S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M14×1.5 female / M22×1.5 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SDAD80X50S Is Used
Elevator Stage Lifting
Raises and lowers a 115 kg machining sub-platform vertically, utilizing the equal 2267.8 N bidirectional force to prevent gravitational drift bias during descent.
Dual-End Transfer Mechanism
Drives a pusher plate on the front rod while a dog mounted on the rear rod trips a solid-state sensor, sequencing a heavy parts shuttle without twisting.
Riveting Head Actuation
Applies 3175 N of precise clamping pressure at 0.7 MPa on an assembly line, relying on the fixed NBR bumper to absorb the shock of the riveting impact.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X50S the Right Cylinder?
When sizing this 80 mm bore model, compare its 2267.8 N @0.5 MPa output against adjacent bores: the SDAD63 yields 1401.5 N, while the SDAD100 provides 3524.9 N. Based on the 0.5 MPa rating, the safe working load is roughly 1361 N (about 60 percent of capacity), allowing a vertical lift of approximately 115.6 kg with a 2:1 safety margin. Choose this 50 mm stroke unit when you need substantial symmetric thrust in a short axial footprint.
The through-rod design resists twisting and permits mounting a tool on one end while tracking position with a switch on the opposite side. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the stroke end and will not hold the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration includes the female rod thread and the S magnet option.
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 SDAD80X50S FAQ
Because the double-rod design creates equal annular areas, the push and pull forces are identical: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa in both directions.
Yes, the through-rod exits both ends to resist rotation and allow dual-end mounting. The -S option includes a built-in magnet for AirTAC reed or electronic switches, letting you drive a tool on one side while tracking position on the opposite end.
