NSK Spacea™ series bearings equipped with Molded Oil™ solid lubricant have solved a problem of premature bearing failures in the extremely demanding environment of a petrochemical plant in Spain. The bearings are installed on the submerged rollers of a conveyor belt and are directly in contact with water, hydrocarbons and particles in suspension from the production process. The ingress of these contaminants was causing the original bearings to fail within a year, resulting in costly maintenance and production downtime.
Few working environments can compete with the potent mix of production demands and pressures routinely encountered in chemical and petrochemical processing. Numerous rotating machines are required to successfully complete these processes and deliver products on time. The use of bearings in such applications provides many technical challenges. One such challenge was faced by NSK
