Flanged bronze-graphite bushings are self-lubricating plain bearings with a high-strength tin bronze or aluminum bronze base, solid lubricant particles (such as graphite or molybdenum disulfide) uniformly embedded in the friction surface, and a flange mounted on the outer ring. They combine the high load-bearing capacity of the metal base with the low friction characteristics of the solid lubricant, ensuring long-term stable operation without the need for additional lubrication. The flange design provides both position limiting and support during installation, preventing axial displacement and making them suitable for use in high-load, low-speed reciprocating or oscillating motion conditions.
