Airtac SDAD Double Rod Slim Cylinder SDAD80X75S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X75S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm 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 SDAD80X75S
The AirTAC SDAD80X75S is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area remains constant, delivering identical push and pull thrust of 2267.8 N at 0.5 MPa. This symmetric force is essential when driving rigid loads that must not skew during direction reversal.
Equipped with a built-in magnet (-S), this 80mm bore unit accepts AirTAC reed or electronic switches directly in the body grooves. The 25mm rod diameter and PT3/8 port handle substantial airflow, while the short profile saves axial mounting depth. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X75S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X75S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 75 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 SDAD80X75S Is Used
Elevator Platform Control
Drives a vertical lifting stage where equal 2267.8 N push and pull forces prevent binding, while the dual-end rod supports a guided carriage.
Dual-End Machining Jig
Clamps a heavy workpiece with one rod end while the opposite end triggers an electronic switch, leveraging the anti-rotation through-rod for rigid holding.
Pallet Transfer Gate
Actuates a heavy diverter gate on a packaging line, using the compact riveted body to fit within tight conveyor frame clearances.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X75S the Right Cylinder?
When sizing this model, compare its 2267.8 N thrust at 0.5 MPa against adjacent bores. Dropping down to the SDAD63 yields 1401.5 N, whereas stepping up to the massive SDAD100 provides 3524.9 N. Based on the 2267.8 N figure, a safe working load is roughly 1361 N (60 percent capacity), translating to a vertical lift capability of about 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and permits mounting a tool on one end with a position dog on the opposite side. Remember that a standard cylinder drifts when air is lost or the valve centers; the NBR bumper only decelerates the stroke end and will not hold the load. For secure positioning, install an external rod lock or pilot-operated check valve. This configuration includes the S magnet and female M14x1.5 rod threads.
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 SDAD80X75S FAQ
The double-rod design provides equal force in both directions: 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the through-rod exits both ends, resisting rotation and allowing you to drive a tool on one side while mounting a dog for a reed or electronic switch on the opposite side. The included S magnet enables this position sensing.
