Precision Double Row Angular Contact Bearings

Double-Row Angular Contact Ball Bearings: Analysis of Advantages, Features and Manufacturing Processes Double-Row Angular Contact Ball Bearings (DRACBB) are precision bearings with two rows of steel balls and angular contact raceways, widely used in machine tool spindles, industrial pumps and automotive drivetrains. Their integrated structural advantages, distinctive features and refined manufacturing processes make them irreplaceable in medium-heavy load scenarios. Their core advantages lie in enhanced load capacity and stability. First, the double-row steel ball design doubles the contact points with raceways, enabling them to withstand 1.5-2 times the radial load and bidirectional axial load of single-row models, ideal for heavy-duty equipment. Second, they offer superior rigidity—integrated inner/outer rings eliminate assembly gaps of combined single-row bearings, ensuring stable operation under variable loads. Third, they have excellent high-speed performance; optimized cage desi…
