日本NTN的5E-RNNU11501C3(807KG)轴承，属于双列圆柱滚子轴承。它结构紧凑，能承受较大径向载荷，运转精度高。因滚子与滚道间接触面积大，具备良好刚性与抗冲击性。常用于机床主轴、工业机械传动部位，可保障设备稳定、高效运行，降低振动与噪声 。 The 5E-RNNU11501C3(807KG) bearing by Japan's NTN belongs to the double-row cylindrical roller bearing type. It has a compact structure and can withstand large radial loads with high running accuracy. Due to the large contact area between the rollers and the raceways, it has good rigidity and shock resistance. It is often used in machine tool spindles and transmission parts of industrial machinery, ensuring the stable and efficient operation of equipment and reducing vibration and noise.
