Drone/UAV Motor Bearings
-- Steady & Reliable Manufacturer --
Brief Description
Ultra-miniature, low-friction bearings specifically designed for high-KV (high RPM) Brushless DC motors in Unmanned Aerial Vehicles (UAVs), maximizing flight efficiency and minimizing weight.
Introduction
The performance of a drone motor is directly tied to the quality and friction of its bearings. These miniature components must operate reliably at speeds often exceeding 50,000 RPM while adding minimal weight to the airframe. We focus on providing bearings with thin cross-sections and extremely low rolling resistance, typically using a shielded (ZZ) design and light, high-speed oil to maximize free spin and extend battery life. Corrosion-resistant steel is frequently used to handle exposure to moisture and environmental contaminants during outdoor flight operations.
