NU312 is a cylindrical roller bearing, 60 mm bore × 130 mm OD × 31 mm wide (2.3622 × 5.1181 × 1.2205 in).

The NU312 is a single row cylindrical roller bearing with a 60mm bore diameter, 130mm outside diameter, and 31mm width. This 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.
