Airtac SDAD Double Rod Slim Cylinder SDAD50X5
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X5 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 5mm 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 SDAD50X5
The AirTAC SDAD50X5 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 symmetry is ideal for driving loads that require consistent momentum in both travel directions.
With a 5 mm stroke, this unit provides a safe working load of roughly 495 N, which is about 60 percent of its 0.5 MPa capacity. The short body design saves axial mounting depth compared to standard profile cylinders. It uses a fixed NBR bumper at each end to decelerate the stroke end, rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X5 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X5 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 SDAD50X5 Is Used
Precision Pinching
Drives a symmetric gripping jaw where the equal 824.7 N extend and retract force ensures consistent clamping pressure on delicate extrusions.
Dual-End Transfer
Mounts a pusher plate on one rod end and a mechanical dog on the opposite end to trip a physical limit switch in a confined assembly cell.
Short-Stroke Lifting
Raises a 42 kg machining fixture by 5 mm using the anti-rotation through-rod to prevent the payload from twisting during the lift cycle.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X5 the Right Cylinder?
When sizing this model against its neighbors, the SDAD40 yields 527.8 N at 0.5 MPa, while the larger SDAD63 provides 1401.5 N at 0.5 MPa. The 50 mm bore offers a balanced middle ground, providing a vertical lift capacity of approximately 42 kg with a 2:1 safety margin. The through-rod geometry resists twisting and lets you mount a tool on one end while leaving the opposite end free for mechanical coupling.
This specific configuration has a 5 mm stroke, a PT1/4 port, and female M10x1.5 rod-end threads on both ends. It lacks the S suffix, meaning there is no piston magnet for reed or electronic switches. Remember that a plain cylinder drifts when air is lost or the valve is centered; use an external rod lock or pilot-operated check valve if you need to hold a load securely.
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 SDAD50X5 FAQ
The push and pull forces are equal because the rod exits both ends. 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.
No, this specific SKU does not have the S suffix, so it lacks a piston magnet and cannot trigger reed or electronic switches. You would need the SDAD50X5S variant for sensing, or use the dual-end through-rod to mount an external mechanical dog.
