N310 is a cylindrical roller bearing, 50 mm bore × 110 mm OD × 27 mm wide (1.9685 × 4.3307 × 1.063 in).
The N310 is a cylindrical roller bearing with a 50mm bore diameter, 110mm outside diameter, and 27mm width. Cylindrical roller bearings use cylindrical rolling elements to provide high radial load capacity and allow for axial displacement of the shaft relative to the housing.
