CR 33x50x6 Industrial Precision Thin Section Deep Groove Ball Bearing - 33 Series
The CR 33 Series bearing, specifically designed to the critical non-standard dimensions of 33mm bore, 50mm outer diameter, and a narrow 6mm width, is engineered for specialized applications requiring extreme space and weight optimization. Constructed from premium, vacuum-degassed high-carbon chromium steel (AISI 52100), this thin-section design maintains exceptional radial and moderate axial load capabilities despite its reduced cross-section. Manufactured to ISO P6 running tolerances (or better), the 33 Series ensures low friction torque and superior running accuracy, making it an ideal choice where standard catalog bearings fail to meet dimensional constraints.
Optimized for high-speed operation and dynamic loading conditions in compact machinery, the CR 33 Series is commonly deployed in precision robotics, miniaturized drive systems, optical positioning equipment, and specialized medical devices. Its narrow profile minimizes overall system weight and footprint, offering significant design flexibility without compromising durability or longevity. This bearing is available with optional low-friction contact seals (2RS) or metal shields (ZZ) to ensure maximum lubricant retention and protection against environmental contaminants, guaranteeing reliable performance across demanding industrial cycles.
