An internationally renowned Italian Food Company was experiencing problems with its fixed tail drum conveyor bearings. Operating in a very damp environment bearings life was only 6 months. The company asked NSK to analyze the application and propose technical solutions to increase the bearing life. A solution was necessary in order to reduce maintenance costs, which had become excessive due to multiple failures. NSK proposed a heavy duty Spherical Roller bearing with Molded-Oil lubrication system. Performance was increased improving machine reliability and reducing maintenance costs.
