Understanding CuZn25Al6Mn4 Bronze Bearings with Graphite: A Comprehensive Guide, Special Brass (SO#50SP2) self lubricating Lubricant Graphite
Bronze bearings have long been the backbone of heavy-duty machinery across various industries due to their durability and reliability. Among the different types of bronze bearings, CuZn25Al6Mn4, often enhanced with graphite, stands out for its exceptional performance in challenging environments. This blog post delves into the properties of CuZn25Al6Mn4 bronze bearings with graphite, their applications, and the advantages they bring to finished parts in machinery. General Information sliding elements are designed for maintenance-free operation. Graphite, enhanced with additives, serves as the lubricant. It’s crucial to note that graphite alone does not provide sufficient lubrication. The lubricant covers 25% to 35% of the sliding surface. Under normal operating conditions, no additional maintenance is required. When applying grease, ensure that the layer is not overly thick. An excessive amount of grease can cause the graphite inserts within the sliding element to be pushed away from the sliding surface, particularly during the initial movement. This could negate the lubrication effect.
