NJ320 is a cylindrical roller bearing, 100 mm bore × 215 mm OD × 47 mm wide (3.937 × 8.4646 × 1.8504 in).
The NJ320 is a cylindrical roller bearing with a 100mm bore diameter, 215mm outside diameter, and 47mm width. This single-row bearing design features high radial load capacity and allows for axial displacement of the shaft relative to the housing, making it suitable for applications where thermal expansion compensation is required.
