Airtac SDAD Double Rod Slim Cylinder SDAD50X90S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X90S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm 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 SDAD50X90S
The AirTAC SDAD50X90S 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 identical push and pull forces of 824.7 N at 0.5 MPa. This symmetric thrust is ideal for balanced load handling.
The integrated piston magnet enables position detection using AirTAC reed or electronic switches mounted in the body grooves. With a 50mm bore and 90mm stroke, the unit provides a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 42 kg with a 2:1 margin. End-of-stroke deceleration is handled by fixed NBR bumpers rather than adjustable cushions.
Airtac SDAD Double Rod Slim Cylinder SDAD50X90S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X90S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 90 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X90S Is Used
Symmetric Transfer Arms
Drives a transfer arm where the equal 824.7 N push and pull force prevents sagging or bias during bidirectional part shuttling on an assembly line.
Dual-End Gauging Station
Mounts a machining fixture on the front rod and a position dog on the rear rod, using the anti-rotation through-rod to maintain strict alignment.
Vertical Lift Platforms
Lifts a 42 kg platen vertically with a 2:1 safety margin, relying on the compact riveted body to save axial depth in tight elevator enclosures.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X90S the Right Cylinder?
When sizing this 50mm bore model, consider the adjacent options: stepping down to the SDAD40 yields 527.8 N at 0.5 MPa, while moving up to the SDAD63 provides 1401.5 N. This SDAD50X90S configuration includes the S option for a built-in magnet and uses a PT1/4 port. The rod ends feature female M10x1.5 threads, and you must leave clearance for the 20mm rod exiting both sides.
The through-rod geometry prevents twisting during operation and allows mounting a tool on one end with a dog or switch on the opposite end. Remember that a plain cylinder drifts if air pressure drops or the valve centers; the NBR bumper only decelerates near stroke end. For load holding without live pressure, install an external rod lock or 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 SDAD50X90S FAQ
The push and pull forces are identical due to the double-rod design. It generates 824.7 N at 0.5 MPa, 1154.5 N at 0.7 MPa, and a theoretical maximum of 168 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
Yes, the 20mm through-rod exits both ends to resist twisting. You can attach a tool to one end and a dog to the other. The S option provides a built-in magnet for AirTAC reed or electronic switches to track position.
