Deep groove ball bearings, as the most common type of rolling bearings, have a unique structure and working principle.
Structural characteristics: Deep groove ball bearings are mainly composed of four parts: inner ring, outer ring, rolling elements, and cage. There are raceways on both the inner and outer rings, and the rolling elements are spherical and roll within the raceways. The function of the cage is to evenly separate the rolling elements, prevent them from colliding and rubbing against each other, and ensure the smooth operation of the bearing.
Working principle: Deep groove ball bearings mainly bear radial loads and can also withstand certain axial loads. When the inner ring of the bearing rotates together with the shaft, the rolling elements roll in the raceway, converting relative motion into rolling friction and greatly reducing frictional resistance. Due to the deep groove shape of its raceway, the contact stress distribution between the rolling elements and the raceway is relatively uniform when subjected to radial loads, which can effectively improve the bearing's load-bearing capacity and service life.
Application areas: Deep groove ball bearings are widely used in various mechanical fields. In the automotive industry, it is commonly used in parts such as engines, transmissions, and wheel hubs; In the field of electric motors, it is a commonly used type of bearing for supporting motor rotors; In industrial machinery, such as machine tools, textile machinery, printing machinery, etc., the support of deep groove ball bearings is also indispensable.
