Cast bronze bushes, particularly those made from self-lubricating bronze materials, are designed to provide reliable and long-lasting performance in low-maintenance applications. The unique composition of self-lubricating bronze alloys enables them to exhibit excellent wear resistance and friction-reducing properties, significantly reducing the need for external lubricants.
These bushings are typically cast using precision casting techniques to ensure consistent material properties and dimensional accuracy. The self-lubricating properties of the bronze alloy are achieved through the addition of specific lubricants or solid lubricants that are evenly distributed within the material. This results in a bearing surface that can operate smoothly and efficiently with minimal maintenance.
Cast bronze bushes made from self-lubricating bronze alloys are widely used in various industries, including automotive, machinery, and power generation. Their ability to withstand high loads, temperatures, and speeds while requiring little to no maintenance makes them a cost-effective and reliable choice for demanding applications.
Your complete source for Bronze Bushings C95500 Aluminum Bronze, Brass, and Copper Alloys sleeve bushings in industry standard sizes.
Aluminum bronze is the highest strength standard copper based alloy. VIIPLUS produces C95400, C95500 and C95900 in standard sizes of bushings. Aluminum in conjunction with iron and nickel in C95500 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.
it is a self-lubricating bearing material that consists of a high quality bearing bronze with solid lubricant pockets. A thin film of solid lubricant aids the running-in process if required.
