NU2300 Series

NU series cylindrical roller bearings are an important bearing type widely used in industrial equipment. They have an open design with parallel raceways on both the inner and outer rings, allowing the bearings to move freely in the axial direction. The main features of NU series bearings are their large load carrying capacity and high rigidity, which are suitable for heavy loads and high-speed operation conditions. Such bearings are usually made of high-quality steel and are heat-treated to ensure their wear resistance and service life. NU series bearings are commonly used in motors, reducers, mechanical transmission systems and other fields. They can effectively reduce friction and wear and improve the operating efficiency of equipment. In addition, they also support a variety of lubrication methods, facilitate maintenance, and adapt to the needs of different working environments.
