Mechanical bearings

Mechanical bearings are key components supporting rotating shafts in machinery, known as the "joints" of machines. They reduce friction and ensure rotational precision, mainly categorized into rolling bearings (with inner/outer rings, rolling elements, cages) and sliding bearings. Common types include deep groove ball bearings, cylindrical roller bearings, angular contact ball bearings, and thrust ball bearings, widely used in automotive, aerospace, machinery manufacturing, and power equipment industries.
