The BCA (NTN) N-306 is a single-row cylindrical roller bearing using a legacy industrial numbering system from BCA Bearings, a historic U.S. bearing brand later associated with NTN in several markets. The N-306 designation corresponds to the standard N306 series, designed for applications requiring high radial load capacity, good speed capability, and durable industrial performance.
Unlike deep groove ball bearings, cylindrical roller bearings are optimized primarily for radial loads and are commonly used in motors, gearboxes, pumps, compressors, and power transmission systems.
Note: Legacy BCA numbering may vary by production era. Exact dimensions and internal design should be verified before replacement.
