The CR 52658 is a robust double-row angular contact ball bearing engineered for exceptional performance in highly demanding industrial applications. Featuring precise dimensions—a 90 mm bore (d), 165 mm outer diameter (D), and 45 mm width (B)—this precision component is designed to accommodate significant combined radial and axial loads, providing superior rigidity compared to single-row configurations. The inherent design utilizes optimized contact angles to manage thrust in both directions simultaneously, making it an indispensable component for gearboxes, heavy pumps, and high-speed machine tool spindles where positional accuracy and structural integrity are critical. It boasts a substantial dynamic load rating (Cr) of 125 kN.
Constructed from premium high-carbon chrome steel (SAE 52100) and finished with advanced surface hardening, the Model 52658 guarantees extended operational life and dramatically reduced maintenance intervals. Choosing the CR brand ensures maximal uptime due to highly reliable running performance, even under challenging conditions of high vibration, misalignment, or cyclical loading profiles. This component is optimized for low friction and stable temperature operation, providing significant product lifecycle cost advantages by reducing premature failure risks and ensuring consistently stable operation across a wide range of application parameters.
