推压蜗杄轴原用标准型号NTN1825C 3RNU进口轴承装配。因长期运转引起疲劳点蚀而报废。换用相同型号轴承由于进口备件困难,往往造成因轴承损坏而停产。我们根据原进口轴承结构型式及受力方向 Push the cochlear shaft with the original standard model NTN1825C 3RNU imported bearings assembly. Due to long-term fatigue caused by pitting and scrapped. For the same type of bearing due to the difficulty of imported spare parts, often resulting in bearing failure and stop production. We based on the original structure of imported bearings and force direction
