Airtac SDAD Double Rod Slim Cylinder SDAD80X80S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X80S 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 SDAD80X80S
The AirTAC SDAD80X80S 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 exactly 2267.8 N of push and pull force at 0.5 MPa. This symmetric output is a major advantage when driving heavy loads that require consistent momentum in both strokes.
The integrated piston magnet enables position sensing with AirTAC reed or electronic switches. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the mass, rather than an adjustable air cushion. The 25 mm rod resists twisting, allowing you to mount a tool on one end and a dog on the opposite side.
Airtac SDAD Double Rod Slim Cylinder SDAD80X80S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X80S |
|---|---|
| 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 SDAD80X80S Is Used
Gripper Actuation
Provides 2267.8 N of equal push and pull force at 0.5 MPa to drive heavy mechanical grippers without rotational deflection during high-speed clamping.
Vertical Lift Stations
Lifts approximately 115.6 kg loads with a 2:1 safety margin, using the through-rod to maintain vertical alignment and prevent twisting on the descent.
Dual-End Transfer
Mounts a work tool on one rod end and a position dog on the opposite end, leveraging the 80 mm stroke to sync operations across a conveyor lane.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X80S the Right Cylinder?
When sizing this 80 mm bore, compare its 2267.8 N at 0.5 MPa against the smaller SDAD63 at 1401.5 N and the larger SDAD100 at 3524.9 N. This positions the SDAD80X80S perfectly for medium-heavy tasks, offering a safe working load around 1361 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of roughly 115.6 kg with a 2:1 safety margin.
The through-rod geometry prevents rotation and enables dual-end mounting, but a plain cylinder will drift if air is lost or the valve is centered. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration includes the S magnet, female M14x1.5 rod threads, and a PT3/8 port.
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 SDAD80X80S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end; for load holding you need an external rod lock or pilot-operated check valve.
