  Measurement Before Bearing Installations

  When installing rolling bearings, the dial gauge should be fixed on the end face of the box shell first, so that the top of the contact head of the meter can migrate the transfer bearing on the raceway of the bearing shaft ring. While migrating the transfer, check the dial gauge pointer. If the pointer is swaying, it is clear that the shaft ring and the middle line of the shaft are not vertical.If the shell hole is deeper, y...

  How To Solve The Problem Of WSBC Bearing Shaft Holding

  After WSBC bearing seizes the shaft, the reasons can be found from several aspects: (1) Whether there is oil leakage in the grinding head. (2) Whether the oil sump is short of oil, and whether the oil level is lower than the indication line on the oil mark. There is a kind of flat grinding lubricating oil which is prepared with kerosene, which is volatile. When the grinder is in normal use, the operator shoul...
