Our laboratory is equipped with advanced material performance testing and analysis instruments, allowing us to strictly control every detail of product design and production, ensuring superior product quality. Indron® bearings, seals, and gaskets are more durable than ordinary bearing materials under various conditions, including dry friction, water lubrication (clean water or water containing sand and mud), non-lubrication, grease lubrication, and even under impact load conditions.

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.
