CuSn14 Bronze Bushes – Self-Lubricating Graphite Plugged Bearings

self lubricating CuSn14 Bronze Bushes

CuSn14 Bronze bushes are high-performance bearings made from a copper-tin alloy, offering excellent strength, elasticity, and wear resistance. With graphite plugging, these bushes are self-lubricating, significantly reducing the need for maintenance and increasing their longevity. These bushes are widely used in heavy-duty and industrial applications where low friction and high load-bearing capacity are required.
