ATC307 Material Composition

ATCORP, ATC-307 Bimetal bearing material is a sliding bushing with steel Backing and a CuPb5Sn10 surface sliding layer.Suitable for fat or oil lubrication, lower friction factor, Shock and vibration resistance, good lubricity and wear resistance. Oil holes, oil holes or oil tanks can be set The sliding layer can be refined to improve the matching accuracy. Suitable for high load and medium speed conditions.These sliding bushings are used in applications with high Loads and medium speeds .Steel Backing provides strength to Bimetal structure while soft Sliding layer of CuPb5Sn10 helps to improve lubrication with strong wear resistant properties. Can be set in oil holes, grease indents or oil pockets.ATC-307 Material comes with three options like tin flash, copper flash or Zn Flashing also to avoid rusting of steel during transit /storage

Benefits of ATC307

  • The steel backing provides exceptional mechanical strength and rigidity, enabling the bushing to withstand significant static and dynamic loads without deformation or failure.
  • The CuPb5Sn10 alloy provides a low-friction interface, reducing wear and extending the lifespan of machinery. Exhibits good resistance to fatigue, particularly at higher temperatures.
  • The bronze layer, metallurgically bonded to the steel, efficiently draws heat away from the sliding surface, preventing overheating, especially under high load/speed conditions. This enhanced thermal conductivity contributes to stable performance and longer lifespan.
  • Sliding layer of CuPb5Sn10 offers inherent lubricating properties.
  • Steel+CuPb5Sn10 bushings are a reliable and cost-effective choice for demanding applications requiring strong, wear-resistant bearings, especially when considering the need for periodic lubrication and proper installation.
