Product Description
Material Structure & Composition
Cross-section diagram showing steel-backed bronze alloy bimetal bushing with graphite-filled oil pockets
ZR-030G graphite filled steel copper bimetal bushing combines low carbon steel backing with sintered bronze alloy CuSn10Pb10 and graphite-filled oil pockets for superior self-lubricating performance.
  • Sintered bronze liner material: CuPb10Sn10 provides excellent wear resistance with low friction and high load capacity
  • Metal backing: Low carbon steel delivers exceptional load carrying capacity and superior heat dissipation
  • Minimum 25% graphite lubricant in oil pockets enhances self-lubrication performance
