Lead-free bearing material for highly loaded engines

  • 46 Accesses


Daido Metal has developed a completely lead-free bearing consisting of a copper-tin-bismuth-molybdenum carbide bearing alloy on a steel back with bismuth/silver dual layers as an overlay. It is both lead-free and suitable for high specific load conditions.
