Inch-sized deep groove ball bearings:
Inch-sized deep groove ball bearings are one of the most widely used types of rolling bearings. They are mainly composed of outer rings, inner rings, steel balls, and retainers. Their structure is simple, with a low friction coefficient, high limit rotational speed, and the ability to withstand radial and axial loads even in cases of significant clearance. These bearings follow the inch-sized standard and are suitable for high-speed rotating machinery. They are widely used in automotive components, household appliances, and other fields.
