Airtac SDAD Double Rod Slim Cylinder SDAD80X75B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X75B 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 SDAD80X75B
The AirTAC SDAD80X75B is a double-acting compact 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 an identical push and pull force of 2267.8 N at 0.5 MPa. This symmetric output is highly advantageous for driving loads that require balanced resistance in both directions.
This specific SKU includes the B option, meaning the 25 mm rods feature male M22x1.5 threads at both ends for direct tool mounting. The short body design saves axial mounting depth where larger profile cylinders will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X75B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X75B |
|---|---|
| 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 SDAD80X75B Is Used
Balanced Lift Station
Lifts 115 kg vertical loads safely with a 2:1 margin, utilizing the equal 2267.8 N extend and retract forces to prevent sagging on the return stroke.
Dual-End Transfer
Drives a push plate on the front male M22x1.5 rod end while using the opposite rod end to trigger a mechanical dog, maximizing layout efficiency.
Anti-Rotation Guide
Handles heavy-duty straightening tasks where the 25 mm through-rod resists twisting forces that would ruin part alignment under 3175 N of thrust.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X75B the Right Cylinder?
When sizing this unit, consider the adjacent bores: stepping down to the SDAD63 yields 1401.5 N at 0.5 MPa, while stepping up to the SDAD100 provides 3524.9 N at 0.5 MPa. For this 80 mm bore, a safe working load is approximately 1361 N (about 60 percent of the 0.5 MPa figure), allowing a vertical lift of roughly 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and permits mounting a tool on one end and a dog on the opposite side. Note that this non-magnet version cannot support reed or electronic switches. Furthermore, the cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; utilize an external rod lock or pilot-operated check valve for 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 SDAD80X75B FAQ
The push and pull forces are identical at 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU lacks the S option and has no piston magnet, so it cannot trigger reed or electronic switches. You would need the SDAD80X75BS variant for position sensing.
