- Ball Bearing: Ball bearings, including deep groove ball bearings, utilize spherical balls as rolling elements that move between inner and outer raceways. They are primarily designed to support radial loads, with some designs capable of handling limited axial loads. Ball bearings are commonly used in applications where smooth and efficient rotation is required, such as in electric motors, pumps, and gearboxes.

Plain Bearings: Also known as bushings or sleeve bearings, plain bearings consist of a simple cylindrical design without rolling elements. They rely on a sliding motion to reduce friction and are often used in low-speed, high-load applications such as in agricultural machinery, construction equipment, and industrial machinery. Plain bearings are valued for their ability to handle heavy loads and operate in harsh environments.

Hebei International Equipment Manufacturing Expo and Hebei International Hardware Expo have been held since 2004, and have been successfully held for 18 sessions. The EXPO integrates exhibition, summit forum and business exchange, and is an industry event of considerable scale, grade and influence in North China.
