NU317 is a cylindrical roller bearing, 85 mm bore × 180 mm OD × 41 mm wide (3.3465 × 7.0866 × 1.6142 in).

The NU317 is a single row cylindrical roller bearing with an 85mm bore diameter, 180mm outside diameter, and 41mm width. This NU-type design features a two-rib inner ring and no ribs on the outer ring, allowing axial displacement of the shaft relative to the housing to accommodate thermal expansion.
