0.3mm-50.80mm Bearing Steel Ball Used For UAV Drone Precision Medical Equipment
Application of steel balls in drones:
Steel balls are mainly used for the ball bearing part of bearings in drones. Bearings are critical rotating components in drones, and the quality and performance of steel balls directly affect the lifespan and operational efficiency of bearings. High quality steel balls can withstand high loads and high speeds, while also having low noise and rust prevention functions, which are crucial for the stable operation of drones
Classification and characteristics of steel balls:
Steel balls are divided into ground steel balls, forged steel balls, and cast steel balls according to the production and processing technology.
According to the processing materials, they are divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, and alloy steel balls.
Bearing steel balls are important basic components in industry, while alloy steel balls are mainly made of added metal elements such as carbon, chromium, manganese, molybdenum, etc. They are generated through forging, spinning, rolling, and casting, and have high strength and wear resistance
