Performance characteristics: Bearing scraper machine adopts single row cylindrical roller bearings and tapered roller bearings, cylindrical roller bearings without inner ring ribs in axial force under the action of floating, when the shell, heat release good amount of expansion can improve the rigidity of the shaft. The tapered roller bearings can meet the problems of large installed power and high load. The rigidity of the shaft is improved and the installation and disassembly are convenient.
