Deep groove ball bearings are a fundamental component in mechanical systems, designed to handle both radial and axial loads with high precision and efficiency. They feature a simple yet robust design, consisting of an inner ring, outer ring, steel balls, and a cage to maintain ball spacing. Commonly used in motors, pumps, conveyors, and industrial machinery, these bearings offer low friction, high-speed capability, and durability. Popular variants include shielded or sealed bearings for contamination protection, as well as stainless steel or ceramic options for specialized environments. Key specifications include bore size, outer diameter, width, and load ratings, making them versatile for automation, robotics, and MRO applications.
