Airtac SDAD Double Rod Slim Cylinder SDAD80X90S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X90S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 90mm 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 SDAD80X90S
The AirTAC SDAD80X90S is a compact double-acting cylinder featuring a 25 mm piston rod exiting both ends of its riveted body. Because the rod occupies both chambers, the annular area remains identical in either direction, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetric thrust is ideal for driving loads that require consistent resistance without twisting.
Designed to save axial mounting depth, the short footprint accommodates tight machinery where standard actuators fail to fit. The unit incorporates a fixed NBR bumper at each end to decelerate the stroke, operating effectively across a 30-500 mm/s speed range. Equipped with a built-in magnet, it supports AirTAC reed or electronic switches for precise end-position detection.
Airtac SDAD Double Rod Slim Cylinder SDAD80X90S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X90S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 SDAD80X90S Is Used
Symmetric Lift Stations
Drives vertical lifting platforms requiring 2267.8 N of equal force in both directions, ensuring stable ascent and descent without load twisting.
Dual-End Transfer Arms
Uses the through-rod anti-rotation feature to mount a gripper on one end and a position dog on the other for synchronized part handling.
Riveting Press Jigs
Fits into compact press machinery where the 90 mm stroke and fixed NBR bumpers absorb the end-of-stroke shock during repetitive metal joining.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X90S the Right Cylinder?
When sizing this 80 mm bore actuator, compare its 2267.8 N output at 0.5 MPa against adjacent models. Stepping down to the SDAD63 provides 1401.5 N, whereas the larger SDAD100 offers 3524.9 N. A practical safe working load is approximately 1361 N, allowing a vertical lift of roughly 115.6 kg with a 2:1 safety margin. This specific configuration includes the S option for magnetic sensing and standard female M14x1.5 rod-end threads on both sides.
The through-rod geometry prevents rotation and permits mounting a tool on one end while fitting a dog on the opposite side. Remember that a plain cylinder drifts if air pressure drops or the valve centers, as the fixed bumper only decelerates near stroke end rather than locking the load. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 SDAD80X90S FAQ
The force is identical in both directions due to the double-rod design. It generates 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 resists twisting and allows you to drive a tool on one end while mounting a dog on the opposite end. The included S magnet enables tracking with AirTAC reed or electronic switches via the body sensor grooves.
