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