The sleeve and bushing, are the key parts for a cold rolling hot galvanization line, are installed on the heads and arms of the sink roll and the stabilizing roll and used to serve as the drive bearings of these rolls. They must tolerate the challenge from high temperature, corrosion by molten zinc and abrasion. For this reason, traditional products have the disadvantages of a short service life, poor stability and high comprehensive cost. With advanced materials and special process, we have developed the sleeve and bushing series with a broad range of advantages like resistance against high temperature, resistance against abrasion and stable operation. They can effectively help customers improve product quality and reduce the comprehensive cost, thereby satisfying customer demands for different production lines.
