Ball bearings are mechanical components that use balls as rolling elements, mainly used to support rotation, reduce friction, and withstand radial and axial loads. Its core structure includes an inner ring, an outer ring, balls, a cage, and a seal. The balls are evenly distributed through the cage to avoid friction, while the seal prevents contaminants from entering.
main types
Deep groove ball bearings: the most common type, suitable for high-speed and low friction scenarios, such as household appliances or small machinery. For example, TMB's 6204-ZZ bearing (size 20mm × 47mm × 14mm) belongs to this category.
Angular contact ball bearings: capable of withstanding both radial and axial loads simultaneously, commonly used in precision equipment such as machine tools and pumps
