Lead-free bronze bearings
Lead-free bronze bearings are a type of bearing made from a bronze alloy that does not contain lead, making them an environmentally friendly alternative to traditional bearings that use lead as a lubricant or wear-resistant material. These bearings are designed for applications where environmental regulations or health concerns make lead-based bearings unsuitable.
Lead-free bronze alloys typically use materials like tin, aluminum, bismuth, and silicon to replace lead while still providing good wear resistance, strength, and corrosion resistance. These alloys are commonly used in industries such as automotive, industrial machinery, and marine applications where high performance and durability are essential.
