UAV Bushings

We CNC machine PEEK and bronze bushings to +/- 0.005 mm tolerances. Specialized anodizing and dry-film lubricants optimize friction coefficients for high-RPM applications.

Our flexible manufacturing cell excels in small-batch runs, accommodating complex geometries and press-fit requirements. We ensure superior concentricity and surface finishes (Ra 0.4), addressing critical thermal expansion and load-bearing concerns in aerodynamic drone assemblies.

How do you ensure the correct "Press-Fit" for our housing?

A bushing is useless if it spins inside the housing rather than the shaft. We maintain tolerances as tight as +/-0.005 mm to match your specified fitment class (e.g., H7/p6). This ensures the bushing stays seated permanently without needing messy structural adhesives.

How are our custom dimensions and material blends protected?

While bushings seem simple, the specific clearances and material composites are often the result of months of R&D. We provide signed NDAs and ensure that any custom-engineered bushing is treated as proprietary IP, never to be added to our public catalog or shared with competitors.

How do you prevent "Stiction" in pivot joints?

Engineers worry about "stiction" (static friction) causing jerky movements in gimbals or folding arms. We solve this by using PTFE-lined or MoS2-coated materials that provide a low coefficient of friction, ensuring smooth, linear movement from the moment force is applied.

Do you offer specialized coatings for harsh environments?

Yes. For drones operating in maritime or sandy environments, we offer electroless nickel plating or passivation for the backing shells. This prevents corrosion between the bushing and the aluminum frame, which can lead to "frozen" joints.

What is the lead time for custom-sized prototypes?

For CNC-turned metal bushings (Bronze or Stainless), we can ship first-article samples in 4–7 business days. For custom-molded polymer bushings requiring new tooling, the lead time depends on the quantity, including the validation of the mold flow and cooling rates.

How do we choose between Bronze and High-Performance Polymers?

Selection depends on your PV (Pressure-Velocity) rating. For high-load folding arms, we recommend oil-impregnated bronze for its durability. For weight-sensitive or non-conductive applications, we suggest PEEK or specialized polymers, which offer significant weight savings over metal.
