ACL 7M1532H-STD Main Bearing Set

The ACL 7M1532H-STD Main Bearing Set is engineered for high-performance applications, specifically tailored for BMW M20, M50, M52, and M54 engines with a displacement of 1919CC, an 80.0mm bore, and a 66.0mm stroke. These tri-metal bearings are designed to withstand the rigors of higher RPM conditions while maintaining optimal performance and reliability.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, crucial for high-revving engines.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring secure retention within the housing.
  • Increased crush improves bearing retention, allowing for better performance under load.
  • Elimination of flash plating on the back of the bearings promotes heat transfer and maximizes grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, facilitating the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and enhance oil flow to the connecting rod bearings.
  • Tight wall tolerances ensure consistent clearances, vital for maintaining engine performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts, enhancing fitment precision.
