UTILIZATION OF BEARING LIFE IN KENANA SUGAR FACTORY

Elbashir Ali Hammad, Ahmed Elnour Mohamed, Osama Mohammed Ahmed

Abstract


Basic principles for bearing life calculation were briefly reviewed and applied to bearings in easily accessible pumping units in three sections for sugar process operations in Kenana Sugar Factory. Calculated lives were found to be 2.8 and 4.7 seasons, depending on the specifications of the bearings and the applied loads. Cost of bearings for the studied units was 2,187 SDG (US$ 893). Bearings in factory sections were generally replaced at the end of each cropping season (3840 hours) regardless of their physical conditions. In sections for sugar process operations, this represented only 24 to 36% utilization of the calculated lives. In monetary terms this means that 64 to 76% of the value of the replaced bearings was thrown away at the end of each cropping season. Bearing life calculation, planned and preventive maintenance programs and availability of maintenance tools are factors that could be used to enhance utilization of bearings in Kenana Sugar Factory.
