Airtac SDAD Double Rod Slim Cylinder SDAD80X70S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X70S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 70mm 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 SDAD80X70S
The AirTAC SDAD80X70S 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 on extend and retract, yielding exactly 2267.8 N of force at 0.5 MPa in either direction. This symmetric output is ideal for balancing heavy loads without torque bias.
The 80 mm bore uses a PT3/8 air port and a 25 mm piston rod. Equipped with a built-in magnet (-S), it supports AirTAC reed or electronic switches for end-position sensing. The short body depth saves axial mounting space, while fixed NBR bumpers absorb end-of-stroke shock across the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD80X70S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X70S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 SDAD80X70S Is Used
Symmetric Lift Stations
Drives a lifting platform with equal push and pull force, preventing sagging on the return stroke when handling 115 kg vertical loads.
Anti-Rotation Guiding
The 25 mm through-rod resists twisting during heavy clamping, maintaining precise alignment for machining fixtures.
Dual-End Transfer
Mounts a pusher on one end and a magnetic dog on the other to trigger reed switches, synchronizing conveyor transfers.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X70S the Right Cylinder?
When sizing this model, compare it to its neighbors: the SDAD63 provides 1401.5 N at 0.5 MPa, while the SDAD100 offers 3524.9 N. The SDAD80X70S sits comfortably in the middle, providing a safe working load of roughly 1361 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity of approximately 115.6 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting, allowing you to mount a tool on one end and a position dog on the opposite side. Note that a plain cylinder drifts when air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for load holding. This configuration includes the -S magnet for sensing and female M14x1.5 rod-end threads on both sides.
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 SDAD80X70S 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.
Yes, the through-rod design allows you to drive a tool on one end while mounting a dog or switch on the opposite end. The -S magnet enables detection by AirTAC reed or electronic switches.
