The B15-83 RICH is a specialized single row deep groove ball bearing specifically engineered for automotive alternator applications. With a 15 mm bore and a robust 18 mm width, this bearing is designed to handle the high rotational speeds and thermal stresses typically found in vehicle charging systems. Unlike standard deep groove bearings, alternator-specific models like the B15-83 are built to withstand constant vibration and the axial/radial load fluctuations caused by drive belt tension. The high-purity steel cage ensures precise roller guidance and structural integrity at high RPMs. This open-type configuration is often used in assemblies where integrated housing seals are present or where specialized high-speed grease is applied during the final installation. Manufactured to precision tolerances, it ensures quiet operation and a long service life for critical electrical components.
Transparency Note: This bearing is manufactured under the RICH brand. The code B15-83 is used for identification purposes and does not imply affiliation with other manufacturers.
