Core classification of bearings
May 13,2026
According to the friction mode, it can be divided into rolling bearings (mainstream, low friction, high precision) and sliding bearings (heavy-duty, low-speed, high-precision scenarios).
Rolling bearing: composed of inner ring, outer ring, rolling elements (balls/rollers), and cage.
According to the rolling elements: ball bearings (point contact, high-speed light load), roller bearings (line contact, low-speed heavy load).
According to the direction of load: radial bearings (mainly radial), thrust bearings (mainly axial).
