CR 15x140x12 Thin Section Deep Groove Ball Bearing | High Precision Industrial Machinery

The CR 15x140x12 bearing is engineered as a highly specialized thin section deep groove ball bearing, designed for applications where robust radial stability is required but space constraints demand an extremely large outer diameter relative to a small bore and narrow cross-section. Constructed from high-carbon chrome steel (52100), this unit delivers superior fatigue life and exceptional resistance to wear. Its specific geometry minimizes the required envelope volume while maximizing precision, making it ideal for critical mounting points that necessitate high rotational accuracy, low friction, and reduced overall weight. The standard P6 precision tolerance ensures reliable performance in demanding industrial environments. Optimized for use in high-tech machinery, robotics, optical equipment, and specialized indexing tables, the CR 15x140x12 excels where standard bearings fail to meet the stringent requirements of a minimized sectional area. This bearing provides exceptional stiffness and load distribution characteristics across its narrow profile (12mm width), ensuring reliable operation even under moderate combined loads. By choosing CR, industrial engineers gain access to a proven component solution that balances maximized operational uptime with minimal maintenance requirements, ensuring system efficiency and longevity in highly specialized mechanical assemblies.
