Solid Self-Lubricating Series

Bronze Octagonal Bushing

The octagonal bushing made of CuSn6Zn6Pb3 (tin bronze) and graphite precision machining is a self-lubricating bearing with solid lubricant embedded in the bushing, designed for operation in harsh conditions where oil lubrication is difficult or impossible. This bearing combines the high strength, wear resistance, and corrosion resistance of tin bronze alloy with the self-lubricating properties of solid lubricants, providing a reliable and maintenance-free solution. Depending on different application scenarios, this product is suitable for both heavy load low speed and light load medium speed high temperature conditions. It ensures equipment reliability and extends service life when used in applications involving heavy loads, impacts, and harsh lubrication conditions.
Applicable industries:It is widely used in industries such as petroleum, metallurgy, mining, construction machinery, and automobiles.
