Applications of Bearings in Civil Unmanned Aerial Vehicles

Pursuit of civilian drones Lightweight, high rotational speed, low noise, low friction, long endurance, and vibration resistance. The bearing as a whole is compact, precise, lightweight, and highly accurate.

I. Core Role

Supports high-speed rotation of the motor rotor, reduces friction-related power consumption, and enhances flight endurance.
Smooth rotation with minimal vibration ensures clear, blur-free aerial footage.
Lightweight design to reduce the overall weight of the machine.
High-temperature resistance, high-frequency start-stop capability, and suitability for repeated takeoff and landing flights.
Dustproof and waterproof, suitable for outdoor conditions with wind, rain, and dust.

II. Specific Application Sites

Brushless Motor Spindle Bearing The heart of a drone’s propulsion system is typically a miniature, high-precision stainless-steel bearing that operates at tens of thousands of RPM with smooth, low-friction performance—directly determining how stable the flight is and how quickly power is consumed.
Gimbal stabilization bearing The camera’s three-axis pitch, roll, and yaw bearings deliver smooth, flexible motion with minimal backlash, ensuring stable, shake-free aerial footage.
Robotic arm folding hinge bearing The drone’s joint bearings are designed for smooth, repeated folding and unfolding—no looseness, no sticking.
Propeller mounting bracket, transmission system bearings Withstands rotor tensile forces and high-altitude vibrations, prevents eccentric oscillation, and ensures flight safety.
Landing Gear Shock Absorbing Rotary Bearing The takeoff and landing buffer steering reduces impact upon touchdown, protecting the airframe and motors.
