NJ315 is a cylindrical roller bearing, 75 mm bore × 160 mm OD × 37 mm wide (2.9528 × 6.2992 × 1.4567 in).

The NJ315 is a cylindrical roller bearing with a 75mm bore diameter, 160mm outside diameter, and 37mm width. This single-row bearing 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.
