Water-lubricated rubber bearings are mainly used in vertical axial flow pumps and mixed flow pumps. The rubber bearings serve as supports between the shaft and sleeve. They come in types such as copper sleeve rubber bearings, iron casing rubber bearings, bearing strips, and all-rubber bearings. They are manufactured using the molding method. They are primarily used in ship axial flow pumps, deep well pumps, etc., as supports for paddle blades and pump blades.Water-lubricated rubber bearings are primarily used in vertical axial flow pumps and mixed flow pumps, especially suitable for circulating water pumps, washing pumps, cooling water pumps, seawater pumps, and feed and drainage pumps in nuclear power plants and thermal power stations. On the other hand, due to the water pollution issues caused by oil leakage in oil-lubricated bearings, the water lubrication method has regained significant attention. Rubber bearings are also widely used in the bearings of ship stern shafts, rudder shafts, and the main shaft bearings of dredger cutting heads. In machinery, rubber bearings generally serve the primary function of supporting and reducing friction. Therefore, the precision and noise of the bearings directly affect the operation and lifespan of the machinery.
