NNU4180M bearing alignment in Coal Vertical Mill roller 400X650X250 MM oil lubrication
Within the coal industry, vertical roller mills are becoming more important as more coal producers look to increase their use of clinker substitute materials instead of importing clinker to meet localised rises in cement demand. The VRM vertical roller mill will use the cylindrical roller bearing and spherical roller bearing.Because the roller mill will need to bear heavy load, so when the factory choose the bearing very carefully.
NNU4180M double row cylindrical roller bearing had matched the spherical roller bearing 24180ECAW33 used for coal VRM equipment.
