N318 is a cylindrical roller bearing, 90 mm bore × 190 mm OD × 43 mm wide (3.5433 × 7.4803 × 1.6929 in).

The N318 is a cylindrical roller bearing with a 90mm bore diameter, 190mm outside diameter, and 43mm width. This single-row bearing design uses cylindrical rollers between the inner and outer rings, providing high radial load capacity and allowing for axial displacement of the shaft relative to the housing.
