Deep groove ball bearings are one of the most widely used bearing types in industry.  They are primarily designed to withstand radial loads, but can also handle combined radial and axial loads. In applications with high rotational speeds where thrust bearings are unsuitable, they can also support bidirectional pure axial loads. These bearings offer advantages such as low maintenance requirements and cost-effectiveness, making them highly versatile.

Deep groove ball bearings come in a wide variety of types, including standard types (60000 series), types with a retaining ring groove, types with single or double-sided dust shields or seals, and types with a flanged outer ring, catering to different sealing and installation needs.

By size, deep groove ball bearings can be categorized as miniature (outer diameter < 26mm), small (28–55mm), medium (60–115mm), large (120–190mm), extra large (200–430mm), and extra-extra large (over 440mm), covering applications from precision instruments to heavy machinery.

Bearing manufacturing is a precision process involving multiple steps, often utilizing forming and grinding technologies to achieve micron-level dimensional accuracy, ensuring smooth rotation and long service life.

Common installation methods include press-fit and heat-fit. Press-fit uses a sleeve to protect the bearing from direct impact; heat-fit simplifies tight-fit assembly by utilizing thermal expansion and contraction, with the heating temperature controlled below 100°C to prevent material tempering and performance degradation.

Deep groove ball bearings are widely used in electric motors, automobiles, home appliances, agricultural machinery, and various transmission systems, serving as an indispensable core component in many equipment drive systems, earning market trust for their reliability and cost-effectiveness.
