Abstract: The primary sources of bearing failure are lack of lubrication and contaminant ingress. Industrial sealing devices are the primary protection against bearing failure. When the sealing device fails, bearing failure is imminent. Therefore, extending the life of sealing devices extends bearing life and in turn improves equipment uptime. Whether the equipment in question is a pulverizer, a turbine, conveyance equipment or something else altogether, there is usually a bearing system either driving or being driven by the equipment. In any application where power is transmitted from one point to the next, a bearing system is used to support rotating elements (usually a shaft) and to support the related loads, while at the same time reducing power losses due to friction. The most common types of bearings are ball and roller bearings. This paper investigates about various areas and factors that are important for designing a cost effective and a versatile bearing seal for roller conveyor typically used in dusty and environment found in mines and excavation sites.
