The bearing surface (towards the roller head) at the injected fat from the middle of the bearing housing unit and the outside of the bearing housing can not enter inside the mill bearing, and easy-to-loss caused by the mill work in a lean state, leading to early bearing failure.
Improved bearing oil passage and additional oiling mouth, the inside of the bearing housing (toward the barrel) to improve the effect of greasing bearings get a good lubrication, most of the mill is greased. Determined due to the structure of the vertical rolling mill roll is rotated, extended bearing life.
Requested by the host components into the designated grease or lubricants;
Amount of interference between the assembly of large bearings and bearings with shaft, housing bore larger must be the bearing oil bath heating oil temperature at 80 degrees Celsius;
Bearing Removal, you must use a special tool for drawing class, non-beating direct bearing with an iron;
Bearing assembly and disassembly, should avoid the rolling element cage force or deformation.
