Airtac SDAD Double Rod Slim Cylinder SDAD50X15B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X15B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 15mm 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 SDAD50X15B
The AirTAC SDAD50X15B 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 vital when driving loads that must remain balanced throughout the stroke.
This specific SKU uses male M18x1.5 piston rod threads on both ends, allowing direct mounting of tooling without extra adapters. The 50 mm bore keeps the footprint shallow, while the fixed NBR bumpers absorb end-of-stroke impacts. Note that this base model lacks a piston magnet, so it cannot support position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD50X15B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X15B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 15 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 SDAD50X15B Is Used
Symmetric Transfer Arms
Drives a dual-ended pick-and-place arm where the equal 824.7 N force prevents sagging on the return stroke.
Anti-Rotation Guiding
Uses the through-rod to resist twisting while pushing a straightening jig in a tight 15 mm stroke.
Dual-End Forming
Mounts a male-threaded forming tool on one end and a mechanical stop on the opposite side for synchronized clamping.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X15B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD40 yields 527.8 N at 0.5 MPa, while moving up to the SDAD63 provides 1401.5 N. The 50 mm bore offers a safe working load of roughly 495 N (about 60% of the 0.5 MPa figure) and can vertically lift around 42 kg with a 2:1 safety margin.
The through-rod geometry prevents twisting and lets you mount a tool on one end and a dog on the other. Remember that the fixed NBR bumper only decelerates the stroke end; it does not hold the load. If air pressure drops, the piston will drift, so add an external rod lock or pilot-operated check valve for load holding. This configuration includes male M18x1.5 rod threads, a PT1/4 port, and a 15 mm stroke.
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 SDAD50X15B 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. It never exhibits a lower pull force.
Yes, the through-rod exits both ends with male M18x1.5 threads, allowing you to drive a tool on one side while attaching a dog or secondary fixture on the other. The rod also resists rotational twist during operation.
