NU218 is a cylindrical roller bearing, 90 mm bore × 160 mm OD × 30 mm wide (3.5433 × 6.2992 × 1.1811 in).

The NU218 is a cylindrical roller bearing with a 90mm bore diameter, 160mm outside diameter, and 30mm width. This single-row bearing design features high radial load capacity and allows axial displacement of the shaft relative to the housing, making it suitable for applications where thermal expansion must be accommodated.
