The 6204ZZNR is a single-row deep-groove ball bearing equipped with double metal shields (ZZ) and an outer ring snap ring groove with pre-installed snap ring (NR). It has a standard metric dimension of 20×47×14mm and is manufactured from high-carbon chromium bearing steel. This bearing provides low friction, low noise, and high load capacity, capable of supporting radial and bidirectional axial loads. The snap ring design ensures secure axial location in housing assemblies, making it widely used in electric motors, fans, pumps, conveyors, and general industrial transmission equipment.
