Airtac SDAD Double Rod Slim Cylinder SDAD50X90
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X90 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 SDAD50X90
The AirTAC SDAD50X90 is a double-acting compact 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 you exactly 824.7 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced tooling.
The 50 mm bore uses a PT1/4 port and a 20 mm rod at each end. Its short body design saves axial mounting depth where larger profile cylinders will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not adjustable. This specific SKU lacks a piston magnet, so it cannot directly host magnetic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD50X90 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X90 |
|---|---|
| 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 SDAD50X90 Is Used
Gripper Jaw Synchronization
Drives opposing gripper arms with identical 824.7 N force in both directions, ensuring perfectly centered clamping on heavy automotive castings.
Balanced Vertical Lift
Lifts a 42 kg platen straight up and down using the dual-end rod, relying on the anti-rotation geometry to prevent platform twisting.
Dual-End Transfer Pusher
Pushes a machined bracket across a conveyor with one rod end while a mechanical dog triggers an external limit switch on the opposite end.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X90 the Right Cylinder?
When sizing this 50 mm bore, compare its 824.7 N @0.5 MPa capacity to the adjacent bores: the SDAD40 yields 527.8 N, while the SDAD63 provides 1401.5 N. Based on the 824.7 N figure, a safe working load is roughly 495 N (about 60 percent capacity), translating to a vertical lift of approximately 42 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and permits driving a tool on one end while mounting a dog on the opposite side. Remember that a plain cylinder drifts when air is lost or the valve centers, as the NBR bumper only decelerates near stroke end and acts as neither a lock nor a brake; use an external rod lock for load holding. This model has a 90 mm stroke, female M10x1.5 rod threads, and no magnet.
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 SDAD50X90 FAQ
The push and pull forces are identical because it is a double-rod cylinder. 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 through-rod resists twisting and allows you to mount tooling on one end while using the opposite end for external mechanical tracking. Note that this specific SKU lacks a piston magnet, so it cannot host internal reed or electronic switches; you would need the -S variant for that.
