Airtac SDAD Double Rod Slim Cylinder SDAD80X80
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X80 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 80mm 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 SDAD80X80
The AirTAC SDAD80X80 is a double-acting, double-rod compact cylinder engineered for symmetric load handling. Because a 25 mm rod exits both ends of the riveted body, the annular piston area is identical in each chamber. This geometry delivers an equal push and pull force of 2267.8 N at 0.5 MPa, eliminating directional thrust mismatch.
Featuring an 80 mm bore and an 80 mm stroke, this unit operates via PT3/8 ports and includes fixed NBR bumpers at both ends to absorb end-of-stroke shock. The through-rod design inherently resists twisting, allowing you to drive a primary workpiece on one end while mounting a secondary mechanism or dog on the opposite side. It lacks a piston magnet, so position sensing is not supported on this specific SKU.
Airtac SDAD Double Rod Slim Cylinder SDAD80X80 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X80 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 80 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 SDAD80X80 Is Used
Gripper Synchronization
Drives opposing grippers on both rod ends simultaneously, ensuring perfectly centered part clamping with equal 2267.8 N force during extend and retract strokes.
Vertical Lift Stations
Handles 115.6 kg vertical payloads with a 2:1 safety margin, relying on the dual-end rod to prevent platform twist during elevation cycles.
Dual-End Machining
Mounts a cutting tool on the front rod and a depth-dog on the rear rod, leveraging the anti-rotation property to maintain strict machining tolerances.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X80 the Right Cylinder?
When sizing this 80 mm bore model, consider the adjacent options in the series. Stepping down to the SDAD63 yields 1401.5 N at 0.5 MPa, whereas moving up to the SDAD100 provides 3524.9 N at 0.5 MPa. The SDAD80X80 strikes a balance with 2267.8 N at 0.5 MPa, offering a safe working load of roughly 1361 N for a 2:1 safety factor, or a vertical lift capacity of about 115.6 kg.
The through-rod geometry provides superior anti-rotation stability compared to single-rod designs. Note that a plain cylinder does not hold position upon air loss or valve centering; the piston will drift. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration features female M14x1.5 rod-end threads, no magnet, and fixed NBR bumpers rather than adjustable air cushions.
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 SDAD80X80 FAQ
The SDAD80X80 delivers equal force in both directions due to its double-rod design. It outputs 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum 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 dual-end mounting. However, because this specific SKU lacks the S magnet option, it cannot directly accept AirTAC reed or electronic switches; you would need the SDAD80X80S variant for internal magnetic sensing.
