From the bearing for idler bearing for and the upper seat in the middle seat outer idler (toward roller head) cannot inject oil well into the mill bearing for inside idler, and easy loss, caused by bearing for idler mill work surface is in poor state, leading to bearing for idler early failure.
For this reason, the oil way of bearing for idler seat is improved, and the oil inlet is added to the inner side of bearing for idler block (facing the roller body) to improve the effect of grease injection. Bearing for idler has been lubricated well, most of the rolling mills now use grease lubrication. The service life of bearing for idler is prolonged because the structure of the vertical mill determines that the roll is rotated.
Injection of specified grease or lubricating oil as required by the main part of the host;
When assembling large bearing for idler and bearing for idler products with larger volume between axle and seat hole, we must heat oil bath for bearing for idler, and the oil temperature is about 80 degrees Celsius.
When the bearing for idler is dismantled, the special tool of drawing class must be used, and the bearing for idler is strictly prohibited by the iron.
When bearing for idler is assembled and disassembled, the force or deformation of the roller and retainer should be avoided.
