Airtac SDAD Double Rod Slim Cylinder SDAD80X45
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X45 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 45mm 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 SDAD80X45
The AirTAC SDAD80X45 is a compact double-acting 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 exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetry prevents twisting and simplifies balancing for heavy loads.
Designed to save axial mounting depth, this 80mm bore unit uses a PT3/8 port and a 25mm rod. It hits a 45mm stroke with a fixed NBR bumper at each end to decelerate impact. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD80X45 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X45 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 45 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 SDAD80X45 Is Used
Symmetric Lift Stations
Drives a lifting platform where equal 2267.8 N push and pull forces prevent sagging on the return stroke.
Anti-Rotation Guiding
Handles a 45mm clamping stroke where the dual 25mm rods resist twisting under offset loads.
Dual-End Tooling
Mounts a forming die on one end while the opposite rod side drives a mechanical ejector simultaneously.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X45 the Right Cylinder?
When sizing this model, consider the SDAD63 which provides 1401.5 N at 0.5 MPa, or step up to the SDAD100 yielding 3524.9 N at 0.5 MPa. The SDAD80X45 strikes a middle ground, offering a safe working load of roughly 1361 N for a 2:1 safety factor, translating to a vertical lift capacity around 115.6 kg.
The through-rod geometry allows mounting a tool on one end and a dog on the opposite side. Remember that a standard cylinder drifts when air is removed or a valve centers; use an external rod lock or pilot-operated check valve for load holding. This configuration confirms an 80mm bore, 45mm stroke, female M14x1.5 rod threads, and no magnet.
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 SDAD80X45 FAQ
The push and pull forces are equal because of the double-rod design. It generates 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.
Only if you select the -S magnet option. This specific SDAD80X45 SKU has no internal piston magnet, meaning it cannot trigger AirTAC reed or electronic switches. The through-rod does allow external mechanical tracking via a dog on the opposite end.
