6805-2RS C3 Bicycle Bearing Thin Section Bearing High Speed for Electric Motor Wheels Tools Home Appliance
The 6805 2RS Ceramic Bearing is a high-performance, thin-section deep groove ball bearing designed for high-speed applications, particularly in bikes and other precision machinery. This bearing features ceramic rolling elements, which provide exceptional strength, low friction, and resistance to wear and corrosion. With C3 clearance, it offers optimal internal clearance for reduced friction and efficient performance, even under high-speed or high-temperature conditions. The double rubber seals (2RS) provide excellent protection against dust, debris, and moisture, making it ideal for outdoor and demanding environments. Its thin-section design ensures a compact and lightweight solution for applications where space and weight are critical.
