NUP318 is a cylindrical roller bearing, 90 mm bore × 190 mm OD × 43 mm wide (3.5433 × 7.4803 × 1.6929 in).

The NUP318 is a cylindrical roller bearing with a 90mm bore diameter, 190mm outside diameter, and 43mm width. This bearing type features high radial load capacity and allows for axial displacement of the shaft relative to the housing in one direction due to its single rib design on the outer ring.
