Product Details

The King Engine Bearings MB5557SI1.0 is a complete crankshaft main bearing set engineered for reliable engine rebuilding performance. Constructed from King's bi-metal silicon aluminum material, these bearings deliver consistent protection and long service life in medium-duty applications.

Material & Construction:

  • Bi-Metal Silicon Aluminum — aluminum-based bearing material strengthened with 2.5–3% silicon content
  • Well-suited for medium load engines and applications featuring nodular cast iron crankshafts
  • Aluminum alloy construction provides excellent conformability and corrosion resistance
  • Precision manufactured to tight tolerances for proper oil film maintenance and crankshaft protection

Size Designation:

  • 1.0mm oversize — designed for crankshafts that have been reground to a 1.0mm undersize journal specification

Key Features:

  • Full main bearing set for complete bottom-end rebuild
  • Engineered to meet or exceed OEM specifications
  • Consistent wall thickness for accurate oil clearance control
  • Suitable for standard street and light-performance rebuilds

King Engine Bearings has been a trusted name in engine bearing manufacturing since 1960, offering a comprehensive range of sizes and materials to support both OEM-replacement and performance rebuilds.
