Kugellager Ball Bearing A high quality ball bearing designed to support rotating shafts with minimal friction. It enables smooth rotation and helps resist wear under typical radial and axial loads. Key benefits - Reduces friction for efficient, quiet operation - Enables smooth rotation of shafts in a range of machines - Handles radial and axial loads within design limits - Improves service life when properly lubricated and sealed - Available in multiple bore sizes to fit common shaft diameters - Made from hardened steel for durability; stainless variants may be available Key attributes - Function: provides low friction support for rotating components - Compatibility: suitable for standard shaft and housing configurations; confirm bore, outer diameter, and width to ensure fit - Size: offered in a range of bore sizes; check product listing for exact measurements - Material: races and balls typically chrome steel; cage options include steel, brass, or polymer; corrosion-resistant versions available - Performance: precision machined for reliable operation at intended speeds and loads; requires proper lubrication Use scenarios - Bicycle wheel hub or scooter wheel assemblies requiring smooth rotation and low rolling resistance - Robotic actuators, grippers, or conveyor systems where precise shaft support is needed - Hobbyist CNC machines, 3D printers, drones, RC models, and other small machinery that rely on reliable bearing rotation
