Partial data from THORDON product description

Under the same conditions, INDRON® elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON® bearing has longer service life, higher reliability and lower maintenance cost.

What bearing materials are more suitable as the materials used for water pump guide bearings, Babbitt alloy, rubber, ceramics or new polymer materials? It is advisable to take account of the lubrication requirements, use environment and maintenance cycle of the equipment.
