Airtac SDAD Double Rod Slim Cylinder SDAD80X65
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X65 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 65mm 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 SDAD80X65
The AirTAC SDAD80X65 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 an identical push and pull force of 2267.8 N at 0.5 MPa. This symmetric output is highly advantageous for manipulating heavy loads without directional force mismatch.
Equipped with a 25 mm rod and a PT3/8 air port, this unit provides substantial thrust in a minimal axial footprint. The integrated fixed NBR bumper decelerates the piston near stroke extremes, while the through-rod geometry inherently resists twisting, allowing you to drive a tool on one end and mount a dog on the opposite side.
Airtac SDAD Double Rod Slim Cylinder SDAD80X65 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X65 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 65 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 SDAD80X65 Is Used
Precision Lift Station
Lifts heavy platens vertically where the equal 2267.8 N bidirectional force prevents sagging on the return stroke.
Dual-End Transfer
Drives a pusher on one rod tip while the opposite tip triggers a mechanical dog, leveraging the anti-rotation through-rod.
Riveting Press
Applies steady clamping pressure from a short riveted body that fits into densely packed assembly machinery.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X65 the Right Cylinder?
When sizing this 80 mm bore unit, consider the SDAD63 which yields 1401.5 N at 0.5 MPa, or step up to the SDAD100 providing 3524.9 N at 0.5 MPa. This SDAD80X65 configuration specifies a 65 mm stroke, female M14x1.5 rod-end threads, and no piston magnet, meaning magnetic switches cannot be fitted.
Remember that a standard cylinder does not hold position upon air loss or valve centering; the piston drifts. For secure vertical load holding, integrate an external rod lock or pilot-operated check valve. The fixed NBR bumper absorbs end shocks but is not an adjustable cushion or braking mechanism.
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 SDAD80X65 FAQ
The force is equal in both directions due to the double-rod design: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical max of 463 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both ends, resisting twist and allowing you to mount a tool on one side and a dog or fixture on the other. Note this specific SKU lacks the S magnet option, so it cannot support magnetic switches.
