N306 is a cylindrical roller bearing, 30 mm bore × 72 mm OD × 19 mm wide (1.1811 × 2.8346 × 0.748 in).

The N306 is a single-row cylindrical roller bearing with a 30mm bore diameter, 72mm outside diameter, and 19mm width. Cylindrical roller bearings use cylindrical rolling elements to provide high radial load capacity and allow for axial displacement of the shaft relative to the housing.
