NU320 Single Row NU Type Cylindrical Roller Bearing 100×215×47mm Pressed Steel Cage For Heavy Industrial Reducers & Mining Machinery

NU320 is a single-row NU series cylindrical roller bearing with double ribs on the outer ring and ribless inner ring, dimension 100×215×47mm. It mainly carries heavy radial loads and allows axial displacement between inner and outer rings, featuring low friction and stable operation under impact loads. The separable structure brings convenient installation and maintenance. It is widely applied in heavy reducers, mining conveyors and large motors under harsh industrial working conditions.
