NUP309 is a cylindrical roller bearing, 45 mm bore × 100 mm OD × 25 mm wide (1.7717 × 3.937 × 0.9843 in).

The NUP309 is a cylindrical roller bearing with a 45mm bore diameter, 100mm outside diameter, and 25mm width. This bearing type features cylindrical rollers guided between integral ribs on the outer ring and two ribs on the inner ring, providing high radial load capacity and allowing limited axial displacement in both directions.
