The NTN 6306 RS bearing is a single-row deep groove ball bearing, designed to operate with high radial loads and moderate axial loads in both directions.
The RS designation indicates the presence of a rubber contact seal on one side, which provides effective protection against dust, dirt, and moisture, keeping lubricant in and extending the bearing's life.
It belongs to the 6300 series, characterized by a higher load capacity compared to the 6000 series.
