Airtac SDAD Double Rod Slim Cylinder SDAD50X110S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X110S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 110mm 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 SDAD50X110S
The AirTAC SDAD50X110S 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 824.7 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced actuation tasks.
The 50 mm bore uses a PT1/4 port and a 20 mm piston rod. A built-in magnet (-S) enables position detection with AirTAC reed or electronic switches via the body sensor grooves. The short body design saves axial mounting depth, while fixed NBR bumpers at each end absorb end-of-stroke shock without requiring adjustment.
Airtac SDAD Double Rod Slim Cylinder SDAD50X110S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X110S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 110 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 SDAD50X110S Is Used
Symmetric Gripper Actuation
Drives an opposing jaw set with identical 824.7 N clamping force in both directions, ensuring even pressure on delicate electronics housings.
Balanced Vertical Lift
Raises and lowers a 42 kg tooling platen with a 2:1 safety margin, using the through-rod to prevent platform twist during transit.
Dual-End Profiling Station
Mounts a cutting blade on the front rod and a travel dog on the rear, allowing an electronic switch to trigger a precise 110 mm material feed.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X110S the Right Cylinder?
When sizing this model, consider the neighbouring bores: the SDAD40 yields 527.8 N at 0.5 MPa, whereas the SDAD63 provides 1401.5 N. The 50 mm bore strikes a middle ground, offering a safe working load of roughly 495 N (about 60 percent of the 824.7 N figure) and a vertical lift capacity near 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.
This unit includes the -S magnet for reed or electronic sensing and features female M10x1.5 rod-end threads. Remember that a standard cylinder drifts when air is lost or the valve centres; the fixed bumper only decelerates the stroke end and will not hold the load. For secure load holding without live pressure, install 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 SDAD50X110S FAQ
The double-rod design provides equal force in both directions: 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.
Yes, the through-rod exits both ends to resist rotation and allow dual-end mounting. The included -S magnet works with AirTAC reed or electronic switches fitted to the body grooves.
