In summary, main bearings are primarily responsible for supporting the rotational motion of the crankshaft and withstanding radial loads, while thrust bearings are designed to counteract axial forces and maintain the axial position of the crankshaft. Both types of bearings play critical roles in ensuring the smooth and reliable operation of engines and machinery.

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.

   - Spherical Roller Bearings: Spherical roller bearings are designed to support heavy radial loads, as well as moderate axial loads, and are capable of accommodating misalignment. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.
