Deep groove ball bearings are the most commonly used and versatile rolling bearings in mechanical engineering. They mainly consist of an inner ring, an outer ring with continuous deep raceways, precision steel balls, and a retainer (cage) that keeps balls evenly spaced and prevents friction between them.

Primarily designed to bear radial loads, they can also support moderate axial loads in both directions. With low friction, low noise, low vibration and high limit speed, they operate stably under high‑speed conditions. Their simple structure ensures easy installation, disassembly and daily maintenance, while high dimensional accuracy and good rigidity guarantee reliable performance and long service life.

Available in multiple series (60, 62, 63, etc.) and sizes, they suit various working environments. They are widely applied in electric motors, fans, water pumps, household appliances, automobiles, machine tools, textile machinery and other general equipment, acting as a critical component for supporting rotating shafts and reducing friction in power transmission systems.
